                              For Immediate Release
                         MacDermid Announces Cash Tender Offer For
                                 W. Canning Plc.

MacDermid, Incorporated ("MacDermid"), a world-wide manufacturer of specialty 
chemical products and equipment for electronics, metal finishing, and graphic 
arts, announced today that the Boards of MacDermid (UK) Limited ("MacDermid 
UK"), a wholly owned subsidiary of MacDermid and W. Canning, Plc. ("Canning") 
have reached an agreement on the terms of a recommended cash offer to acquire 
the whole of the ordinary share capital of Canning not already owned by 
MacDermid.  The offer values Canning at 300 United Kingdom pence per share.  
If fully subscribed, the value of the offer is just over 89 million UK pounds 
(approximately $150 million at current exchange rates).  The offer has been 
unanimously recommended by the Directors of the Board of Canning.  The 
transaction is expected to modestly add to MacDermid's earnings per share in 
the first full fiscal year beginning April 1, 1999, and increase in 
subsequent years.

Canning is a leading international specialty chemicals group with world-wide 
operations in Birmingham England.  Founded in 1785, and trading on the London 
stock exchange, Canning's principal business is plating additives similar to 
MacDermid's Industrial Products business.  Other niche businesses in offshore 
synthetic lubricants and fluids, and in adhesives and sealants, represent a 
small diversification opportunity for MacDermid.  Canning has previously 
announced a strategic review of its businesses which MacDermid will re-
examine with particular focus on Canning's fuel additives business.

MacDermid's Chairman, Dan Leever, today said, "We are delighted that we are 
joining two companies with such proud history.  Over many years of personal 
contact and professional cooperation in the area of technology licensing, we 
have developed a deep respect for the people of Canning.  We look forward to 
welcoming the Canning team to the Clan MacDermid.  We expect the combination 
to be additive to earnings per share in the first year and to be increasingly 
accretive as we realize operating efficiencies.  The addition of niche 
businesses should enhance our earnings diversity.  The combination of Canning 
and our Industrial Products group will create a leading world-wide position 
and a platform for growth.  Upon successful completion of the offer, 
MacDermid's Industrial Products business will be similar in revenues to our 
electronics business, thereby greatly accelerating our long-standing strategy 
of balancing our portfolio.  We are truly excited about the prospects for 
this long-standing, profitable, growing business area upon which MacDermid 
was founded."

In the year ended December 31, 1997, Canning reported revenue from continuing 
operations of UK PDS 74.0 million and operating profits from continuing 
operations of UK PDS 8.8 million (approximately $125 million and $15 million 
at current exchange rates).  Canning acquired a US-based industrial products 
business during the current fiscal year which helped increase revenues to UK 
PDS 41.3 million (approximately $70 million) in the six months ended June 30, 
1998.

The offer has committed financing provided by NationsBank N.A., a subsidiary 
of BankAmerica Corporation.  MacDermid hopes to close the transaction before 
the end of 1998.  MacDermid is being advised by Lazard Brothers & Co. Canning 
is being advised by SG Hambros.
