Title: COIN-TYPE ARTICLE
Abstract:
The invention relates to the production of coins, medals, commemorative tokens and similar products, which are protected against counterfeit. Proposed is a coin-type article with a polished and/or relief surface having sections onto which a micro-relief is applied. Said micro-relief takes the form of an ordered set of projections and recesses with a size of 0.5-5.0 μm, which constitutes an integral part of the decorative design of the article exterior. When said article is exposed to a beam of a full spectrum halogen lamp at an angle of 45 degrees to the surface of the coin-type article, the intensity of a beam reflected specularly from a surface section comprising an applied micro-relief is at least 48% lower than the intensity of a beam reflected specularly from a section of the article surface which does not comprise a micro-relief. The technical result of the invention is to produce articles which comprise a security feature with a higher degree of protection as a result of the reliability of detection thereof and the presence of such a security feature incorporated into the decorative design of the article exterior.
