Abstract:
1. A process for producing a relief printing plate precursor for laser engraving comprising: a layer formation step of forming a relief-forming layer from a resin composition for laser engraving; and a crosslinking step of crosslinking the relief-forming layer by light, heat, or both to thus obtain a relief printing plate precursor having a crosslinked relief-forming layer, wherein the resin composition for laser engraving comprises (Component A) an acrylic block copolymer, (Component B) a crosslinking agent, and (Component C) a crosslinking catalyst, Component A is a copolymer which includes only two or more acrylic blocks, And the content of a binder polymer other than Component A in the resin composition is less than 10 wt % of Component A.
