Patent ID: 8632957

Claim:
A process for making a relief printing plate, comprising: a layer formation step of forming a relief-forming layer from a resin composition comprising (Component A) a compound having a hydrolyzable silyl group and/or a silanol group, (Component B) a binder polymer, and (Component C) a peroxide; a crosslinking step of thermally crosslinking the relief-forming layer to thus obtain a relief printing plate precursor having a crosslinked relief-forming layer; and an engraving step of laser-engraving the relief printing plate precursor having a crosslinked relief-forming layer to thus form a relief layer, wherein Component A is a compound represented by Formula (A-1) or Formula (A-2) below; wherein, in Formula (A-1) and Formula (A-2), R B denotes an ester bond, an amide bond, a urethane bond, a urea bond, or an imino group, L 1 denotes an n-valent linking group, L 2 denotes a divalent linking group, L s1 denotes an m-valent linking group, L 3 denotes a divalent linking group, n and m independently denote an integer of 1 or greater, R 1 to R 3 independently denote a hydrogen atom, a halogen atom, or a monovalent organic substituent, at least one of R 1 to R 3 denotes a hydrolyzable group selected from the group consisting of an alkoxy group, a mercapto group, a halogen atom, an amide group, an acetoxy group, an amino group, and an isopropenoxy group, or a hydroxy group, the divalent or n-valent linking group denoted by L 1 to L 3 is a group formed from at least one type of atom selected from the group consisting of a carbon atom, a hydrogen atom, an oxygen atom, a nitrogen atom, and a sulfur atom, and the m-valent linking group denoted by L s1 is a group formed from a sulfur atom and at least one type of atom selected from the group consisting of a carbon atom, a hydrogen atom, an oxygen atom, a nitrogen atom, and a sulfur atom.
