Image recording material based on the polymeric photobase generator containing oxime-urethane groups

A polymeric photobase generator containing oxime-urethane groups was prepar ed from copolymerization of MMA with N-[4-(benzophenoneoximinocarbonylamino ) phenyl]maleimide, a maleimide monomer containing oxime-urethane group, an d its properties as an image recording material were studied. The irradiati on of this copolymer with UV light dissociates the urethane linkage to resu lt in the formation of aromatic amino groups, which can be developed by the diazo-coupling reaction. Various colors could be developed depending on th e phenolic coupling reagents as the developer.
