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, [R1SO3CH(R2)]R3 (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), and a polymer synthesized by the monomer containing it, are also described.
