Patent ID: 7105276

Claim:
A heat mode negative image recording material comprising (A′) a polymer compound that is insoluble in water but is soluble in an alkali aqueous solution and has at least one of structural units represented by the following formulae (4) and (5) in an amount of 30 mol % or more; (B), a photothermal conversion agent; and (C′) a compound forming radicals by heat mode exposure with light that is capable of being absorbed by the photothermal conversion agent (B), the heat mode negative image recording material being capable of recording an image by heat mode exposure: wherein A, B and X each independently represents an oxygen atom, a sulfur atom or —N—(R 25 )—; L and M each independently represents a divalent organic group; R 13 to R 24 each independently represents a monovalent organic group; Y represents an oxygen atom, a sulfur atom, —N—(R 26 )— or a phenylene group, which may have a substituent; and R 25 and R 26 each independently represents a hydrogen atom or a monovalent organic group.
