FIELD: physics, optics.
SUBSTANCE: invention relates to a film (1), designed to protect and decorate articles. The film includes at least one transparent replicating layer (2), having a diffracting relief structure (3) and a reflecting layer. The reflecting layer is formed from at least one layer (4) of pigmented lacquer, which is placed in the immediate vicinity of the diffracting relief structure (3). Refraction indices n1 of at least one lacquer layer (4) and n2 of the replicating layer (2) assume values whose difference is in the range from 0.05 to 0.7. Luminosity L* of at least one lacquer layer (4) is in the range from 0 to 90. Disclosed also is a method of producing said film and use thereof to coat car number plates and other articles to protect from forgery, coupled with an optically variable decorative effect.
EFFECT: improved properties of the film.
