FOR IMMEDIATE RELEASE                                               EXHIBIT 99.1

           KRONOS INTERNATIONAL, INC. REPORTS FIRST QUARTER RESULTS

HOUSTON,  TEXAS  - May 6,  2003  -  Kronos  International,  Inc.  ("KII"  or the
"Company"), an indirect wholly owned subsidiary of NL Industries, Inc. (NYSE:NL)
today  reported  net  income  for the  first  quarter  of 2003 of $14.8  million
compared with $8.0 million in the first quarter of 2002.

The Company's  titanium dioxide pigments ("TiO2")  operating income in the first
quarter  of 2003 was $29.0  million  compared  with  $14.3  million in the first
quarter of 2002.  The 103% increase in operating  income from first quarter 2002
was  primarily   attributable  to  higher  average  selling  prices  and  higher
production volume. Compared with the fourth quarter of 2002, operating income in
the first quarter of 2003 increased $17.2 million,  or 146%, on higher sales and
production volumes, higher average selling prices and lower operating costs.

EBITDA   (defined  as  operating   income  plus   depreciation,   depletion  and
amortization  expense) was $37.1  million in the first  quarter of 2003 compared
with  $20.6  million  in the first  quarter  of 2002.  Compared  with the fourth
quarter of 2002, EBITDA increased $18.2 million, or 96%.

KII's average selling price in billing currencies (which excludes the effects of
foreign  currency  translation)  during the first  quarter of 2003 was 9% higher
than the first  quarter of 2002 and 2% higher  than the fourth  quarter of 2002.
The average selling price in billing  currencies in March 2003 was comparable to
the average selling price for the first quarter of 2003.

The Company's first quarter 2003 average selling price expressed in U.S. dollars
(computed using actual foreign  currency  exchange rates  prevailing  during the
respective  periods)  was 27% higher  than the first  quarter of 2002 and was 8%
higher than the fourth quarter of 2002. The average  selling price  expressed in
U.S.  dollars in March 2003 was comparable to the average  selling price for the
first quarter of 2003. Comparisons of the Company's average selling prices using
actual  foreign  currency  exchange  rates  are  significantly  affected  by the
continued weakness of the U.S. dollar relative primarily to the euro,  Norwegian
kroner and United Kingdom pound sterling.  A majority of the Company's net sales
and a majority  of its  production  and other costs are  incurred in  currencies
other than the U.S. dollar, and the net effect of foreign currency  fluctuations
on the Company's operating income was not significant.

The  Company's  first  quarter  2003  sales  volume  of 79,500  metric  tons was
comparable  to the  first  quarter  of 2002 and  increased  24% from the  fourth
quarter of 2002.  Compared to the fourth quarter of 2002, sales volume increased
in all major markets.

The Company's first quarter 2003 production  volume of 78,500 metric tons was 9%
higher than the first quarter of 2002 and 14% higher than the fourth  quarter of
2002,  respectively.  Operating  rates in the first quarter of 2003 were at near
full capacity compared with 96% of capacity in the first quarter of 2002 and 85%
of capacity in the fourth quarter of 2002.  Decreased  production  volume in the
fourth  quarter of 2002 was primarily due to maintenance  stops.  Finished goods
inventory  levels  at the end of the first  quarter  of 2003  decreased  2% from
December 2002 levels and represented under two months of sales.

                                   Page 1 of 5


Capital  expenditures  in the first  quarter of 2003 were $5.6 million  compared
with $4.8  million in the first  quarter of 2002.  First  quarter  2002  capital
expenditures included an aggregate of $1.2 million related to the reconstruction
of the Leverkusen, Germany sulfate plant damaged in the March 2001 fire.

Lawrence A. Wigdor,  Chief Executive  Officer,  stated,  "Operating  profits and
EBITDA  for the  first  quarter  of 2003  exceeded  our  expectations  driven by
stronger than anticipated sales volume. Sales volume was a first quarter Company
record,  while production volume was an all-time  quarterly Company record.  Our
debottlenecking  efforts have proven  successful  and we  currently  have annual
capacity of  approximately  319,000 metric tons. We currently  expect TiO2 sales
volume for full year 2003 to  approximate  full year 2002  levels,  with  higher
average selling prices in 2003 compared to 2002. EBITDA and operating income are
forecasted to be above 2002 levels. We remain cautious about the outlook for the
second  half of 2003 as there  remains a high degree of  uncertainty  concerning
worldwide economic conditions."

Interest expense to third parties in the first quarter of 2003 was $7.9 million,
an increase of $7.2 million from the first quarter 2002  primarily due to higher
levels of outstanding debt and associated currency effects.  Interest expense to
affiliates  decreased  $9.7  million  from the first  quarter of 2002 due to the
repayment  of  loans  from  affiliates  in June  2002  using  proceeds  from the
Company's (euro)285 million Senior Secured Notes offering (the "Notes").

Interest income from affiliates decreased $8.9 million from the first quarter of
2002 due to the  redemption  and  extinguishment  of all notes  receivable  from
affiliates in July 2002.

Net  corporate  currency  transaction  losses in 2002  related  primarily to the
Company's  dollar-denominated,  11.75% Second-tier Senior Mirror Note payable to
Kronos, Inc., which was repaid in June 2002 using a portion of the proceeds from
the Notes offering.

The  Company's  provision for income taxes for the first quarter of 2003 differs
from the normally expected  statutory rate due to the geographic mix of earnings
and the  utilization of certain tax attributes  that previously did not meet the
"more-likely-than-not"  recognition criteria. The Company's provision for income
taxes for the first quarter of 2002 differs from the normally expected statutory
rate due  principally to the geographic  mix of earnings,  currency  transaction
losses on which no income tax benefit was  recognized  and adjustment to certain
other deferred tax liabilities.

Outstanding  indebtedness  at March 31, 2003 was  euro-equivalent  326.6 million
($350.2   million   using  March  31,  2003   exchange   rates)   compared  with
euro-equivalent  312.8  million at  December  31,  2002  ($325.9  million  using
December 31, 2002 exchange  rates).  The increase in indebtedness  was primarily
attributable to additional  borrowings of (euro)15  million ($16.1 million using
March 31, 2003  exchange  rates) on the European  revolving  credit  facility of
certain of the Company's subsidiaries.

In an effort to provide Note holders with additional  information  regarding the
Company's results as determined by accounting  principles  generally accepted in
the  United  States of America  ("GAAP"),  the  Company  has  disclosed  certain
non-GAAP  information which the Company believes may provide useful  information
to investors:

o     The Company  discloses  percentage  changes in its average  TiO2 selling
      prices in billing  currencies  (which  excludes  the  effects of foreign
      currency translation),  so that such changes can be analyzed without the
      impact  of  changes  in  foreign   currency   exchange  rates,   thereby
      facilitating  period-to-period  comparisons.  Generally,  when  the U.S.
      dollar  either  strengthens  or weakens  against other  currencies,  the
      percentage  change in average selling prices in billing  currencies will
      be higher or lower, respectively,  than such percentage changes would be
      using actual exchange rates prevailing during the respective periods.

o     The Company  discloses  EBITDA  (defined  above) as a supplement  to the
      Company's  operating  income and cash flow from  operations  because the
      Company  believes that EBITDA is a widely used  performance  measure and
      financial  indicator  of cash flows and the  ability  to  service  debt.
      EBITDA  should  not  be  considered  as  an  alternative   to,  or  more
      meaningful than,  operating  income or net income  determined under GAAP
      as an indicator of the Company's  operating  performance,  or cash flows
      from  operating,  investing and financing  activities  determined  under
      GAAP as a measure of  liquidity.  EBITDA is not intended to depict funds

                                   Page 2 of 5


      available for reinvestment or other  discretionary  uses, as the Company
      has  significant  debt  requirements  and other  commitments.  Investors
      should  consider  certain  factors in evaluating  the Company's  EBITDA,
      including  interest  expense,  income taxes,  noncash income and expense
      items,  changes in assets and  liabilities,  capital  expenditures,  and
      other  items  included  in  GAAP  cash  flows  as well  as  future  debt
      repayment requirements and other commitments and contingencies.

A conference call regarding KII's earnings announcement and outlook is scheduled

controversies,  and other  risks and  uncertainties  detailed  in NL's and KII's
Securities and Exchange  Commission  filings.  Should one or more of these risks
materialize (or the  consequences of such a development  worsen),  or should the
underlying  assumptions prove incorrect,  actual results could differ materially
from  those  forecasted  or  expected.  NL and KII  disclaim  any  intention  or
obligation to update publicly or revise such statements,  whether as a result of
new information, future events or otherwise.
