         HITACHI CHEMICAL CO., LTD.  ACQUIRES ACCESS TO FUTURE
                 SPD-SMART LIGHT-CONTROL TECHNOLOGY
                  DEVELOPED BY RESEARCH FRONTIERS


TOKYO, JAPAN and WOODBURY, NEW YORK, July 10, 2007 - Hitachi Chemical Co., Ltd.
(Hitachi Chemical) and Research Frontiers Incorporated (Nasdaq: REFR) announced
today that Hitachi Chemical has committed to pay Research Frontiers 96 million
yen in order to gain guaranteed access to the latest developments in patented
SPD-Smart(tm) light-control technology developed by Research Frontiers Inc.
over the next two years.

Earlier this year, Research Frontiers licensees Hitachi Chemical and Innovative
Glass Corp. announced that Hitachi Chemical was in production of SPD-Smart film
from their new wide-width coating line. The film, which is now being used for
architectural and aircraft applications, and is also at an advanced stage of
development for the automotive and marine industries, electrically controls
the amount of light, glare and heat that passes through glass or plastic
windows, sunroofs, sunvisors, skylights, interior partitions and other
products. Long rolls of SPD-Smart light-control film can easily be shipped
from Hitachi Chemical's production facilities in Ibaraki, Japan to customer
locations across the world where it can be laminated locally into SPD-Smart
glass or plastic products.

Using Hitachi Chemical's SPD film, users can automatically, or with the simple
turn of a dial, control light, heat and glare coming through materials such
as glass or plastic from optically transparent to blocking over 99% of visible
light, and it can be tuned to any level of tint in between. All of this can be
done instantly to increase comfort and conserve energy, and unlike conventional
shading technology, without blocking one's view. SPD-Smart windows and other
products using SPD film also block over 99% of harmful ultraviolet light,
reduce noise and increase security.

Eiji Omori, Department Manager of Hitachi Chemical's Advanced Performance
Materials Strategy Department, noted the strategic importance of SPD-Smart
emulsions and film to Hitachi Chemical's business, and commented: "We work
closely in partnership with Research Frontiers, and currently are offering
our customers the best performing light-control technology in production
anywhere. This latest development allows us to continue to have access to
Research Frontiers' latest improvements in SPD light-control technology so that
we can always offer the best possible products to our customers in the
architectural, automotive, aerospace and marine industries."

Robert L. Saxe, Chairman of Research Frontiers, noted: "Our initial focus
was to assist our licensees get SPD technology into production. Now that
SPD-Smart film is in production, we can now focus our research and development
efforts more towards longer-term improvements in SPD technology."

The film is made using a chemical emulsion patented by Research Frontiers
and manufactured by Hitachi Chemical which is then coated onto a thin plastic
film. This film is then incorporated into a variety of "smart" products
manufactured by other companies where variable light control is desired.

SPD-Smart film technology was awarded a "Best of What's New Award" from
Popular Science magazine for home technology, received the 2007 North American
Frost & Sullivan Award for Excellence in Technology for glass, and was also
recognized as one of the top technologies by the Society of Automotive
Engineers' Aerospace Engineering magazine. SPD technology is covered by over
450 patents and patent applications held by Research Frontiers worldwide.
Currently 33 companies are licensed to use Research Frontiers' patented
SPD light-control technology in emulsions, films, or end-products.
