FIELD: process engineering. ^ SUBSTANCE: invention relates to laminating film comprising several layers for, at least, partial coating of metal substrate subjected to cold forming, and to method of its production. Proposed film comprises aforesaid several layers. It includes transparent bearing film, transparent layer of varnish with diffraction relief structure, and reflection layer. Said transparent bearing film is made from thermoplastic. Its features thickness varying from 19 to 75 mcm and elastic modulus varying from 3500 to 500 N/mm2 in, at least, one direction. At least, one transparent layer of varnish features elastic modulus differing from that of bearing film by 10%, particularly, by less than 5%. ^ EFFECT: higher quality of products. ^ 20 cl, 4 dwg |
