Abstract:
1. A process for pretreating a substrate to be subjected to forming a relief pattern thereon by exposure to actinic radiation, the process comprising treating the substrate with a pretreatment composition prior to coating the substrate with a photosensitive composition, the pretreatment composition comprising: (1) at least one compound having structure VI wherein Y is selected from the group consisting of S, O, NR wherein each R wherein, m is independently an integer from 0 to 4 with the proviso that m=0 only when Y═ n is an integer from 1 to 5; p is an integer of from 1 to 4, and (2) at least one organic solvent; wherein the amount of the compound of Structure VI present in the composition is effective to inhibit residue from forming when a photosensitive composition is coated on the substrate and the resulting coated substrate is subsequently processed to form an image on the substrate, with the proviso that when a polybenzoxazole precursor polymer is used in a negative working photosensitive composition, Y cannot be (HOCH)
