Abstract
Disclosed are a resin composition for laser engraving, including an acrylic block copolymer; a relief printing plate precursor for laser engraving comprising a relief-forming layer formed from the resin composition on a support; a process for producing the relief printing plate precursor; a process of making a relief printing plate using the relief printing plate precursor; and a relief printing plate having a relief layer which is manufactured by the process.
Claims18
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.
