Patent ID: 7112397

Claim:
An image-forming composition comprising (A) a polymeric compound obtained by the addition reaction of a resinous polymer having one or more phenolic hydroxyl group with a silane coupling agent of the following general formula (1) or (2), wherein: X t represents a trimethoxysilyl or triethoxysilyl group; G 1 represents O or COO; R 1 and R 2 each independently represents a hydrogen atom or a methoxy group, with the proviso that both of R 1 and R 2 are not hydrogen atoms at the same time, or R 1 and R 2 are combined together to form a ring through an alkylenedioxy group; R 3 represents (CH 2 ) m , optionally having a hydrocarbon side chain, wherein m is an integer of 3 or greater; X 2 represents a trimethoxysilyl, triethoxysilyl, chlorodimethylsilyl, dichloromethylsilyl or trichlorosilyl group; G 2 represents O or COO; R 4 represents a hydrogen atom or a straight-chain or branched alkyl group; and R 5 represents (CH 2 ) n , optionally having a hydrocarbon side chain, wherein n is an integer of 3 or greater; (B) an acid generator; (C) an infrared absorber; an (D) an alkali-soluble resin; wherein said polymeric compound comprises at least one compound selected from the group consisting of cresol-formaldehyde resins, resol type phenolic resins, pyrogallol-acetone resin, polyvinylphenol, a copolymer of vinylphenol and styrene, and t-butyl-substituted polyvinylphenol resin.
