Abstract:
An image-forming material comprising on a support an acid-generating agent represented by following formula (I) generating an acid by the action of heat or a polymer obtained by polymerizing the acid-generating agent and a compound causing a change in the absorption region of 360 to 700 nm by an intramolecular or intermolecular reaction by the action of an acid, wherein R1 represents an alkyl group, an aryl group, or a heterocyclic group, R2 and R3 each independently represents an alkyl group or an aryl group, excluding that R2 and R3 are simultaneously aryl groups, R2 and R3 may combine to form a ring, and at least one of R2 and R3 has a polymerizing unsaturated group.
