LASER ENGRAVING RESIN COMPOSITION, LASER GRAVING FLEXOGRAPHIC PRINTING PLATE FORM AND ITS MANUFACTURING METHOD, AND FLEXOGRAPHIC PRINTING PLATE AND ITS PLATEMAKING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a laser engraving resin composition by which a flexographic printing plate having superior rigidity of a relief layer, print resistance and organic solution resistance can be obtained.;SOLUTION: A laser engraving resin composition is characterized by containing resin having a partial structure expressed by a (component A) formula (I). R¹ to R⁵ are independently express a hydrogen atom, a halogen atom or a monovalent organic groove, L¹ independently expresses a single bond or a bivalent linking group, two of more of R¹ to R⁵ and L¹ may form a ring by being coupled to each other, R⁶ expresses a hydrogen atom or a monovalent organic group, p expresses an integer of 0 to 6, q expresses 1 or 2, r expresses an integer of 0 to 6, p+q+r is an integer of 3 to 7, and a wavy line portion expresses a coupling position with the other structure.;COPYRIGHT: (C)2014,JPO&INPIT
