Patent ID: 7407731

Claim:
A photosensitive resin composition comprising: (a) at least one polybenzoxazole precursor polymer; (b) at least one compound having Structure VI wherein, V is selected from the group consisting of CH and N, Y is selected from the group consisting of O and NR 3 wherein R 3 is selected from the group consisting of H, CH 3 and C 2 H 5 , R 1 and R 2 are each independently selected from the group consisting of H, C 1 -C 4 alkyl group, C 1 -C 4 alkoxy group, cyclopentyl and cyclohexyl, or R 1 and R 2 can be fused to produce a substituted or unsubstituted benzene ring; and (c) at least one solvent; wherein the amount of the compound of Structure VI present in the composition is an amount effective to inhibit residue from forming when the composition is coated on a substrate and the coated substrate is subsequently processed to form an image on the substrate, and with the proviso that if the polybenzoxazole precursor polymer solely consists of polybenzoxazole precursor polymers that do not contain a photoactive moiety in the polymer, then (d) at least one photoactive compound is also present in the composition.
