SANDWICHED BODY Russian patent published in 2015 - IPC B42D25/30 B32B33/00 

FIELD: process engineering.

SUBSTANCE: invention relates to sandwiched body including first ply with multiple first zones separated by one or several translucent second zones. This body has second ply of translucent material, second ply being arranged under first ply and reflecting ply being located under second ply. Second ply has multiple third zones wherein every microstructure is embedded in the boundary, sideways from first ply, between first ply and reflecting ply coated with reflecting ply. Every microstructure is configured to reflect backward and/or to diffract light backward falling perpendicular to the plane covered by first ply in direction from first ply located in the zone of third zone to first ply area. First ply area is smaller at least 10 times than that of appropriate third zone. Microstructures are arranged in compliance with microstructure grid where spacing between adjacent microstructures in second spatial direction makes less than 300 mcm.

EFFECT: perfected design.
