Application No. 08/113,147
are directed to a photosensitive element which includes a
photosensitive layer comprising an elastomeric microgel
binder, at least one ethylenically unsaturated monomer or
oligomer and a photoinitiator system. Claim 1 is
representative and reads as follows:
1. A photosensitive element comprising a support and a
photosensitive layer, said photosensitive layer comprising:
(a) an elastomeric microgel binder having a core
comprising a homopolymer or copolymer of an
elastomeric monomer and a shell comprising a copolymer of
the elastomeric monomer and a monomer having acidic
functionality, wherein the shell copolymer is
formed by polymerizing the monomer having acidic
functionality with unpolymerized elastomeric monomer from
the core;
(b) at least one ethylenically unsaturated monomer
or oligomer; and
(c) a photoinitiator system.
