A resin composition for laser engraving is provided, which forms a film having good physical properties, imparts good printing durability to a printing plate having a relief forming layer made of the resin composition, and achieves high engraving sensitivity in laser engraving. The resin composition for laser engraving includes a compound (A) having at least two isocyanate groups in its molecule, and a polymer compound (B) having at least one substituent selected from the group consisting of a hydroxyl group and —NHR, in which R represents a hydrogen atom, a linear alkyl group, a branched alkyl group, an alkenyl group, an alkynyl group, a cycloalkyl group, an alkoxy group, an aryl group, or a heterocyclic group.
