NOCOPI TECHNOLOGIES, INC. EXPANDS PRODUCT LINE TO INCLUDE NEW CHILDREN'S
PUBLICATIONS. ANNOUNCES EXCLUSIVE LICENSE WITH PARADISE PRESS, INC. TO PUBLISH
NOCOPI'S NATIONAL AWARD-WINNING RUB-IT AND COLOR ACTIVITY BOOK.

WEST CONSHOHOCKEN, PA. SEPTEMBER 27, 2005, PR NEWSWIRE. Today, Michael A.
Feinstein, M.D., Chairman and CEO of Nocopi Technologies, Inc. (OTC Bulletin
Board: NNUP), announced an expansion of company activities to include the
publication of Children's Books. "This initiative marks an important milestone
for us. We look forward to utilizing our ink and printing technologies to create
a vast array of education and entertainment products," said Dr. Feinstein.

Dr. Feinstein also announced a new exclusive license with PARADISE PRESS, INC.,
WESTIN, FLORIDA for the publication of Nocopi's RUB-IT & COLOR CHILDREN'S BOOKS.
"We are pleased to initiate this new business relationship with Paradise Press
for the sales of our Rub-it & Color Books to children of all ages," said Dr.
Feinstein.

Scott Schear, President of Paradise Press, commented "I really like the Nocopi's
RUB-IT & COLOR technology and think it has the potential to be a big winner."

Paradise Press, Inc. publishes children's coloring and activity books, sticker
books, paint with water books, children's board books, puzzle books and
dictionaries. Paradise Press also licenses some of the major nationally known
names for children's coloring products.

Paradise Press publications are sold to the public in over 20,000 retail outlets
located throughout the United States.

The RUB-IT & COLOR ACTIVITY BOOK, an interactive product, was launched at the
American International TOY Fair in New York City in February, 2004. "These
Activity Books bring a rainbow of colors to life without using crayons, coloring
pencils or markers. Colors magically appear before your eyes, simply by
rubbing/scratching the RUB-IT & COLOR paper. Colors do not stick to your
fingers, and they meet the safety requirements for toxicology testing
ASTM-F963," stated Dr. Feinstein.







Creative Child Magazine awarded the company's RUB-IT & COLOR ACTIVITY Book the
PREFERRED CHOICE AWARD for the year 2004 in the Kid's Travel Toy Category, and
SPECTRUM Magazine named the Activity Book as one of the TOP THREE products at
the 2004 Toy Fair held in New York City earlier that year.

Creative Child Magazine is a bimonthly publication that delivers the latest
information on how to nurture children's creativity. Award winners were judged
and recognized for their excellence in promoting creativity in play.

Spectrum Magazine, also a bimonthly publication, says of the Activity Book:
"it's great for teaching children to color, staying within the lines, and using
different colors in one picture. It is very innovative."

Nocopi Technologies, Inc. is also in the business of developing solutions
against counterfeiting, product diversion, document security, and authentication
via patented technologies (including invisible inks, color changing inks,
reactive thread and document security paper products.)
