Patent ID: 7052822

Claim:
An infrared photosensitive composition, comprising: a binder polymer (A), a polymerizable compound (B), an infrared absorber (C), and a compound (D) which can generate radicals by the action of light or heat, wherein an acid value of a film produced from the composition is from 0.15 mmol/g to 0.8 mmol/g, and wherein the binder polymer (A) has a structural unit represented by the following formula (I): wherein R 1 represents a hydrogen atom or a methyl group; R 2 represents a linking group having 4 to 30 atoms selected from carbon, hydrogen, oxygen, nitrogen, sulfur and halogen; A represents an oxygen atom or —N—R 3 —, in which R 3 represents a hydrogen atom or a monovalent hydrocarbon group having 1 to 10 carbon atoms; and n represents an integer of 1 to 3.
