<p>PURPOSE:To enhance the fineness of patterns, surface smoothness and film thickness accuracy and to improve the environmental resistance by incorporating specific two kinds of compds. and specific photopolymn. initiator into the compsn. CONSTITUTION:This compsn. consists of a photosensitive resin (A) and a pigment. The photopolymn. initiator consisting of a multifunctional acrylate monomer, org. polymer binder, >=1 kinds of the 2-mercapto-5-substd. thiadiazole compds. expressed by the formula I or II, the phenyl ketone compd. expressed by the formula III, and the 2,4,5-triphenyl imidazolyl dimer [e.g. 2-(o- chlorphenyl)-4,5-diphenyl imidazolyl dimer] are incorporated into the component A and such compsn. is used. In the formulas, R1 denotes alkyl, alkylthio, etc.; R2 denotes alkylene; X1 denotes H, 1 to 6C alkyl, etc.; R3 denotes H, prescribed group, etc.</p> |
