FIELD: devices for medicine and agriculture. SUBSTANCE: material which is sensitive to ultraviolet light has temperature softening polymer and 2-6 % of mix of inorganic bismuth compound and at least one complex bismuth compound with organic carbon acids in mole content of 1:0.01-0.1. Polyethylene, polypropylene, polystyrene, polyvinyl chloride, polycarbonate, polyamide and so on may be used as temperature softening polymer. Bismuth halide, hydroxide, oxyfluoride, oxychloride, oxybromide, oxyiodine, oxycarbonate, bismuth sulfate and phosphate, bismuth oxide may be used as inorganic bismuth compound. Bismuth compounds with organic carbonic acids, such as acetic, tartrate, oxalic acids, aromatic carbon acids and their derivatives, such as benzoic, O,M-toluyl, chlorbenzoic, tere[phthalic acids are used as complex bismuth compounds. EFFECT: increased functional capabilities. 1 tbl
