Abstract

FIELD: protection of valuable papers, certificates, credit, cheque and other information cards from duplicating and forgery. SUBSTANCE: information card has backing 2, microrelief 3, transparent layers 4 and 5 applied to microrelief with flat exterior surface in form of figures, patterns and other pictures with refraction indices different from those of adjacent regions of transparent layer. Metallized light reflecting layer is made with microrelief or applied onto microrelief made on backing and located between backing and transparent layer. Scattering of directed white light 1 by microrelief and transparent layer makes it possible to observe in directions of viewing $$$ different colors of regions of figures, signatures, patterns and other pictures of transparent layer against the background of other colors of adjacent region of transparent layer which have different refraction indices. EFFECT: higher efficiency. 2 cl, 3 dwg

Изобретение относится к защите цветных бумаг, удостоверений, кредитных, чековых и других информационных карточек от копирования и подделки. Информационная карточка содержит подложку 2, микрорельеф 3, прозрачный слой 4 и 5, нанесенный на микрорельеф с плоской внешней поверхностью в виде фигур, рисунков и других изображений с различными относительно соседних областей прозрачного слоя показателями преломления. Металлизированный светоотражающий слой выполнен с микрорельефом или нанесен на микрорельеф, выполненный на подложке, и расположен между подложкой и прозрачным слоем. Рассеивание направленного белого света 1 микрорельефом и прозрачным слоем, позволяет наблюдать в направлениях наблюдения различные цвета областей фигур, подписей, рисунков и других изображений прозрачного слоя на фоне других цветов соседних областей прозрачного слоя, имеющих различные показатели преломления.

The invention relates to the protection of colored papers, certificates, credit, check and other information cards from copying and forgery. The information card contains a substrate 2, a microrelief 3, a transparent layer 4 and 5, deposited on a microrelief with a flat outer surface in the form of figures, patterns and other images with different refractive indices relative to neighboring regions of the transparent layer. The metallized reflective layer is made with a microrelief or deposited on a microrelief made on a substrate, and is located between the substrate and the transparent layer. The scattering of directed white light by 1 microrelief and a transparent layer allows observing in the directions of observation different colors of the regions of the figures, signatures, drawings and other images of the transparent layer against the background of other colors of neighboring regions of the transparent layer having different refractive indices.
