NANO-COATING INSCRIBED OPTICALLY AND THERMALLY Russian patent published in 2013 - IPC B41M5/28 B32B7/02 

FIELD: process engineering.

SUBSTANCE: invention relates to nano-coating inscribed optically and thermally to be applied on substrate. Proposed coating comprises first mirror layer that reflects, either itself or at its boundary, electromagnetic waves, second translucent layer applied over said mirror layer or located under it, and, at least, one third later applied on said translucent layer and consisting of metallic, or heavily chromophoric particles, or nanoparticles, or their chemical precursors, or metallic thin film. Translucent layer features thickness <700 nm while of metallic, or heavily chromophoric particles, or nanoparticles features thickness <100 nm. Note here that structure colour variation perceived by human eye is ensured by light effects or by direct contact with, or close approach to hot objects in spatially define and structure way.

EFFECT: furnishing material with data with no printing means.
