PROBLEM TO BE SOLVED: To provide a photosensitive resin laminate for flexographic printing, which has such characteristics as good film strength, scratch resistance, adhesiveness with a photosensitive resin layer, handling property in a platemaking process, drawing property with an infrared laser, solubility in a flexographic developer solvent, and higher sensitivity to infrared laser light, and which includes an infrared ablation layer that can be removed by using an infrared laser.SOLUTION: The photosensitive laminate includes: a support layer (A) 10; a photosensitive resin layer (B) 20 comprising a thermoplastic elastomer, a polymerizable unsaturated monomer, and a photopolymerization initiator; an infrared ablation layer (C) 30 that blocks non-infrared radiation and that can be removed by using an infrared laser; and a cover film (D) 40. The infrared ablation layer (C) contains a modified polyolefin (c1) and an infrared absorbing substance (c2); and the modified polyolefin (c1) comprises at least one polymer selected from chlorine-modified and/or maleic acid modified polyolefin. |
