UNIQUE MATERIAL MARKING METHOD AND PAINT USED FOR ITS IMPLEMENTATION Russian patent published in 2011 - IPC B41M3/14 G07D7/00 C09D11/00 

FIELD: technological processes.

SUBSTANCE: material marking method consists in the fact that there made is paint consisting of binding agent and fine microparticles and/or microencapsulated microdrops having diameter of approximately 40 to 80 mcm. Then, the mark having surface area of about one square centimetre and containing serial registration number is printed on the product by using the above paint. The above mark is lit with the light and chaotic character of distribution, shape and sizes of fine microparticles and/or microencapsulated microdrops are fully flashed; due to which non-reproducible and distinctive background card for the introduced mark is created. And data reads composed of the above background card are subject to filtration by using stop-down lens serving for neutralisation and suppression of any possible reflection of distortion of and damage to patterns, and then the above data reads subject to filtration are identified by means of optic-digital video camera interrelated with software, and view finder. At that, video camera has the possibility of transmitting the data to registration database for further comparison and confirmation of authenticity of the product marked in such a manner.

EFFECT: marking method allows high degree of protection of the product against false fabrication and copying.
