FIELD: chemistry.
SUBSTANCE: invention relates to flexographic printing and concerns photosensitive laminated plastic materials intended for production of flexographic printing plates. The plastic material comprises a support, a layer of photosensitive resin, an IR ablation layer and a protective film. The photosensitive resin comprises a thermoelastoplast, a polymerizable unsaturated monomer, and a photoinitiator. The infrared ablation layer contains a modified polyolefin and an IR absorbing material. The modified polyolefin contains at least one polymer selected from a group comprising chlorine-modified and/or maleic acid-modified polyolefins.
EFFECT: invention enables production of stronger plastic material, improve its solubility and sensitivity to infrared radiation.
