MEMBER FOR DOCUMENT PROTECTION AGAINST IMITATIONS Russian patent published in 2000 - IPC

FIELD: documentation keeping. SUBSTANCE: member has base, protective layer, layer of magnetic plastic material coupled to it in which latent rerecorded magnetic image changeable by means of magnetic recording equipment is formed. Member also includes layer with protecting image and nontransparent layer with protecting image. Layer of magnetic plastic material is placed between layer with protecting image and protective layer, and it is of higher values of magnetization and coercivity. Base is made of translucent material and coupled to layer with protecting image by means of the first layer of thermal adhesive. Layer of magnetic plastic material is coupled to protective layer with the aid of the second layer of thermal adhesive or it constitutes single layer of magnetic thermal adhesive with it. It is made as a layer of regular or irregular structure forming rerecorded magnetic image in plane of layer. EFFECT: enhanced protection. 2 cl, 1 dwg
