Patent ID: 7338748

Claim:
A polymerizable composition comprising a binder polymer having a repeating unit represented by the following formula (I) and a repeating unit having a radical-polymerizable group represented by the following formula (A) or (C), an infrared absorbent, a polymerization initiator and a polymerizable compound, wherein R 1 represents a hydrogen atom or a methyl group; R 2 represents a linking group which includes two or more atoms selected from the group consisting of a carbon atom, a hydrogen atom, an oxygen atom, a nitrogen atom and a sulfur atom and has a number of atoms of 2 to 30; A represents an oxygen atom or —NR 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 5; wherein R 4 , R 5 and R 6 each independently represent a hydrogen atom, or a monovalent substituent; and X represents an oxygen atom, a sulfur atom or N—R 15 in which R 15 represents a hydrogen atom or monovalent organic group; wherein R 12 , R 13 and R 14 each independently represent a hydrogen atom, or a monovalent substituent; and Z represents an oxygen atom, a sulfur atom or N—R 15 , in which R 15 represents a hydrogen atom or a monovalent organic group.
