PROBLEM TO BE SOLVED: To provide a laminate for laser processing having excellent characteristics for laser processing, and a flexography printing plate having excellent printability and workability, and also provide their manufacturing methods. SOLUTION: The laminate for laser processing is provided with a polymer layer for laser processing composed by crosslinking a polymer composition containing an ethylene copolymer, and a base layer laminated on one face of the polymer layer for laser processing, wherein the polymer layer and the base layer can be peeled on an interface. In the manufacturing method of the laminate for laser processing, a polymer sheet for laser processing is formed by crosslinking the polymer composition and a photopolymerizable layer composed of a photopolymerizable composition material such as an elastomer, a compound having an ethylene unsaturated group, a polymerization initiator or the like, and it is irradiated with ultraviolet rays. A printing pattern is formed by engraving the polymer layer for laser processing of the laminate by using laser, and the flexography printing plate can be obtained. |
