Abstract:
Disclosed is a flexographic printing plate precursor in which formation of cracks and wrinkles in an infrared ablation layer is suppressed and the scratch resistance of the layer is improved. The precursor includes a support, photosensitive resin layer, and an infrared ablation layer that are laminated in the order presented. The binder polymer contained in the infrared ablation layer contains a polymer (A) and an acrylic resin (B). The polymer (A) contains the same structural unit as the structural unit contained in the binder polymer in the photosensitive resin layer. The mass ratio (A/B) of the component (A) with respect to the component (B) is within a range of 1/3 to 3/1. The difference between a plastic hardness (Ha) of the infrared ablation layer and a plastic hardness (Hb) of the photosensitive resin layer is 30 mN/mm2 or smaller.
