Title:
LASER-ENGRAVABLE FLEXOGRAPHIC PRINTING PLATE PRECURSOR
Document Type and Number:
WIPO Patent Application WO/2011/122545
Kind Code:
A1
Abstract:
Provided is a high-resolution laser-engravable flexographic printing plate precursor which can be engraved into fine protrudent shapes having suitability for printing. The laser-engravable flexographic printing plate precursor is characterized by comprising a support and, formed thereon, a crosslinked relief formation layer obtained by crosslinking, by chain polymerization and successive crosslinking reactions, a resin composition comprising a monomer (A) capable of chain polymerization, a crosslinking agent (B) which crosslinks through successive reactions, and a crosslinkable polymer (C) having a crosslinkable group that reacts with the crosslinking agent (B). The printing plate precursor is further characterized in that the crosslinked relief formation layer has a storage modulus E' (MPa), measured at 25ºC and a frequency of 100 Hz, that satisfies relationship (a), and further has a maximum tensile elongation at break L (%) at 25ºC that satisfies relationship (b). 1≤E'≤30 (a) 30≤L≤300 (b)
