Abstract:
A self-photosensitive polyimide having a benzophenone moiety and an active hydrogen moiety, and is represented by the formula 1: ##STR10## where R.sub.1 is ##STR11## and R.sub.2 is E-CH.sub.2 -F, where A and B are each independently selected and are an unsubstituted aromatic group, selected from aromatics comprising a monocyclic ring of six carbon atoms, a bicyclic ring of ten carbon atoms and a tricyclic ring of fourteen carbon atoms, and Y is a heteroatom selected from oxygen (O), sulfur (S) and nitrogen (N),E and F are each independently selected from the group consisting of an unsubstituted aromatic group, an aromatic group having at least one substitute (G), where the aromatic group is selected from aromatics comprising a monocyclic ring of six carbon atoms, a bicyclic ring of ten carbon atoms and a tricyclic ring of fourteen carbon atoms, a C.sub.3 -C.sub.10 cycloalkyl, a C.sub.3 -C.sub.10 cycloalkyl having at least one substituent (G) a C.sub.3 -C.sub.10 cycloalkeny, and a C.sub.3 -C.sub.10 cycloalkenyl having at least one substituent (G),where the substituent (G) is selected from the group consisting of a C.sub.1 -C.sub.10 alkyl, an aromatic, unsubstituted or substituted amino, a halide, hydroxy (OH), nitro (NO.sub.2), cyano (CN), thiocyano (SCN), thiol (SH) and carboxyl (COOH)) groups.
