the transparent protective element with multi-layer protection from forgery, method of manufacturing and method of verification of the authenticity of the object protected by u0437u0430u0449 u0438u0442u043du044bu043c element

摘要

the invention belongs to the field of protection against forgery and to verify the authenticity of the objects to be protected.after manufacturing a transparent protective element, according to which (a) are transparent in the visible region of the spectrum awith two working parties; (b) at each of the working parties which form transparent in the visible wavelength range barrier layera method for direct printing using a liquid composition, a solution of organic solvent and polymer varnish.containing 1 - 7% uv u0430u0431u0441u043eu0440u0431u0435u0440u0430 red abroad spectrum of absorption in the field of 400 nm;) u043eu0442u0432u0435u0440u0436u0434u0430u044eu0442 the barrier layer to each of the sides of the carrier a temperature in the range of 70 to 80u00b0u0441;mr.) u0432u043fu0435u0447u0430u0442u044bu0432u0430u044eu0442 at least one latent image carrier at least at one station on each of its working parties, the method of direct printing with beh u0441u0446u0432u0435u0442u043du043eu0439 liquid compositionsa solution of organic solvent and polymer varnish containing 0,5 - 10% u0431u0435u0441u0446u0432u0435u0442u043du043eu0433u043e u0444u043eu0442u043eu0447u0443u0432u0441u0442u0432u0438u0442u0435u043bu044cu043du043eu0433u043e dye with the addition of 0 - 3% uv u0430u0431u0441u043eu0440u0431u0435u0440u0430; d) subjected to the latent image on both sides of the ans. u0435u0440u0436u0434u0435u043du0438u044e at temperatures in the range of70 80u00b0u0441, (e) by a thin protective layer of transparent in the uv wavelength range, for both working side carrier on the surface of the protective element, the u043au043eu044du0444u0444u0438u0446u0438u0435u043d t light protective layeressentially, coincides with the coefficient of refraction material barrier layer, and the hidden imageswhile invisible borders forming latent images with the naked eye, with u0432u043fu0435u0447u0430u0442u0430u043du043du044bu0435 latent images on both sides is working u0435u043bu044f u043au043eu043cu043fu043eu043du0443u044eu0442u0441u044f independently from each other.with the possibility of an independent separate visualization of latent images on each of the working of the host.the protective element to be executed according to the above-mentioned method, the valuable document containing the protective element and the protected object, containing the u0449u0438u0442u043du044bu0439 elementmade according to the above-mentioned method.
