Abstract
An image-forming material is described, comprising on an support an acid-generating agent selected from a sulfonic acid ester of a specific structure generating an acid by the action of heat and the polymer thereof, and a compound causing a light absorption change in the absorption region of from 350 to 700 nm by an intramolecular or intermolecular reaction by the action of an acid. The image-forming material has a high sensitivity and excellent storage stability and gives low haze and good images in the case of performing image formation using a high-output laser light. A sulfonic acid ester derivative represented by the formula, [R SO CH(R )]R (wherein R represents an alkyl group, an aryl group or a heterocyclic group, R and R each independently represents an alkyl group or an aryl group, excluding that R and R are simultaneously aryl groups, R and R may combine to form a ring, and at least one of R and R has a polymerizing unsaturated group), and a polymer synthesized by the monomer containing it, are also described.
