PHOTOSENSITIVE COMPOSITION, IMAGE FORMING MATERIAL AND IMAGE FORMING METHOD

摘要

PROBLEM TO BE SOLVED: To ensure high sensitivity to laser light of long wavelength such as semiconductor laser light and to improve preservability. SOLUTION: This photosensitive compsn. contains a dye having a specified structure andλmax in the range of 630-730nm and an org. peroxide, a diphenyliodonium salt, an org. boron compd. having a specified structure or an O- and N-contg. heterocyclic compd. having a specified structure or contains a dye having a specified structure andλmax in the range of 430-550nm and a diphenyliodonium salt or an org. boron compd. having a specified structure.
