Document Type and Number:

Japanese Patent JP4454156

Kind Code:

B2

Abstract:

The present invention relates to a photo-curable polymer composition comprising(a) a first block copolymer comprising at least two blocks A of polymerised monovinyl aromatic monomer, at least one internal block B of polymerised conjugated diene monomer, and at least one tapered or random block C of polymerised monovinyl aromatic monomer and polymerised conjugated diene monomer and/or at least one block D which may be a block of polymerised conjugated diene monomer or a tapered or random block of polymerised monovinyl aromatic monomer and polymerised conjugated diene monomer, wherein block C is an internal polymer block adjacent a terminal block A or an internal block A which is adjacent to a terminal block D, and block D is a terminal block adjacent an internal block A, and, optionally, a residue of a coupling agent, wherein the residue, if present, is derived from a coupling agent containing alkoxy or epoxy functional groups; and(b) a photo-initiator. The present invention further relates to a flexographic printing plate precursor comprising a photo-curable layer sandwiched between two release films or a release film and a support. In addition, the present invention relates to a cured polymer composition, obtainable by curing the photo-curable composition; to a flexographic printing plate containing the cured polymer composition, and to a process for printing on a substrate with the flexographic printing plate.
