FIELD: photomaterials. SUBSTANCE: method involves application of photopolymerizing composition layer on the substrate (backing), application of transparent diffraction lattice on this layer, irradiation with UV-light from the lattice site and lattice removal. Photopolymerizing composition: photoinitiating agent, oligourethanmethacrylate of the formula (I), given in the description of the invention, with mean molecular mass 2500, and one or several compounds taken from the group consisting of oligourethanacrylate, oligocarbonate methylacrylate, oligoesteracrylate, triacrylatetrimethylolpropane or neopentylglycol diacrylate. EFFECT: improved method of producing. 1 tbl
