PURPOSE: To provide a photopolymerizable mixture capable of providing a photoresist excellent in processing solution resistance by including a polymer binder, an (alk)acrylate of polyhydric alcohol, and a photopolymerization initiator having a specified composition. n CONSTITUTION: A photoreducing pigment (e.g.: xanthene, acrydine pigment) is combined with a trihalogenomethyl compound cuttable by radiation [e.g.: 2,4-bis(trichloromethyl)-6-(4-styrylphenyl)-s-triazine] to prepare a photopolymerization initiator. This photopolymerization initiator component, a polymer binder having at least one photo-oxidizable group (e.g.: methacrylic acid/styrene/n- hexylmethacrylate/2-diethylaminoethyl methacrylate copolymer) and an (alk) acrylate of polyhydric alcohol (e.g.: ethyleneglycol) are included as essential components, whereby a photopolymerizable mixture is produced. n COPYRIGHT: (C)1990,JPO |
