Appeal No. 1997-3801
Application 08/397,960
Appellant’s claimed invention is directed toward a
process for making laminated plastic cards having a thermo-
mechanically sensitive substrate. Appellant states that the 1
conventional laser printing process, wherein a substrate
having an image thereon is passed between heated rollers which
fix or set the print so that it is permanent and stable,
damages thermo-mechanically sensitive substrates
(specification, page 2). Appellant states that a purpose of
the claimed process is to permit thermo-mechanically sensitive
substrates to be used without damage in laser printing, and
that this goal is achieved by use of only partial setting of
the graphic subject matter by radiant heat (specification,
pages 3 and 6). Claim 1 is illustrative and reads as follows:
1. Process for the production of laminated plastic
cards,
comprising a thermo-mechanically sensitive substrate
having a graphic subject matter printed thereon, which
comprises;
1 Appellant states that a thermo-mechanically sensitive
substrate is one which is significantly affected as to its
physical properties, appearance or other properties relevant
to its function as a printed substrate when it is passed
between two rollers which are heated to a minimum temperature
of 120EC and pressed against one another with a minimum
pressure of 150 Kg (specification, pages 4-5).
