Water-soluble terpolymer of acrylamide, diacetone acrylamide, and acrylic acid was prepared by redox initiators in aqueous medium. One component photoresist was synthesized by reaction of terpolymer with 4-azidoaniline. By blending the aqueous acrylamide/diacetone acrylamide copolymer solution with bisazide, 4,4'-diazidostilbene -2,2'-disulfuric acid sodium salt, two component photoresist was prepared. The photosensitivity per azido group unit mole of one component photoresist was 4 times higher than that of two component photoresist. The dot-type pattern was successfully achieved with one component photoresist at low exposure energy, which is prospective to be used as black matrix negative photoresist.
