Patent ID: 8822126

Claim:
A resin composition for laser engraving, comprising a polymerizable compound, a radical polymerization initiator, and a binder polymer, the binder polymer comprising a main chain that comprises at least one of a structure unit represented by the following Formula (I) or a structure unit represented by the following Formula (II): wherein Q represents a partial structure which provides an acid group when it is in the form of -Q-H, the acid group being selected from the group consisting of a sulfonic acid group, a phosphoric acid group, a carboxylic acid group, a phenol group, a 2-methoxyphenol group, a 2-chlorophenol group, a 2-methylhydroxy benzoate group, a 4-methylphenol group, a 1,3-benzenediol group, a 1-naphthol group, a 1,2-benzenediol group, a benzene sulfone amide group, a N-acetylphenylbenzene sulfone amide group, a 4-aminobenzene sulfone amide group, a N-phenyl-4-aminobenzene sulfone amide group, a N-(4-acetylphenyl)-4-aminobenzene sulfone amide group, and an ethyl acetyl acetate group; wherein R 1 to R 3 each independently represent a hydrogen atom, an aliphatic group, an alicyclic group, an aromatic group or a heterocyclic group, and wherein A and B each independently represent an aliphatic connecting group, an alicyclic connecting group, an aromatic connecting group, or a heterocyclic connecting group.
