SINGLE-LAYER FILM FOR IMAGE PROJECTION Russian patent published in 2019 - IPC G02B27/60 

FIELD: image forming devices.

SUBSTANCE: invention relates to optical materials capable of creating a series of visual effects. Single-layer system of projecting images for projecting one or more images includes a structure of reflecting arc-like elements having an upper arc-like surface, a lower surface and an arc-shaped zone confined by upper arc-like and lower surfaces, as well as reflecting pattern from relief microstructures of images located on at least some of upper arched surfaces of arc-shaped elements or inside them. Structure of reflecting arched elements and reflecting pattern from relief microstructures of images are in one layer and interact to project one or more images, where in case of upper arched surface with convex curvature of surface relief microstructures of images extend downwards from this surface and end in arc-shaped zone, and in case of upper arc-like surface with concave surface curvature, relief microstructures of images extend upwards from this surface and end in zone limited by curve of upper arc-shaped surface.

EFFECT: disclosed is a single-layer film for projecting images.
