Abstract (en)
[origin: WO2015040055A1] The invention relates to a method for the cost-effective production of a particularly counterfeit-resistant and tamper-resistant security feature (160) of a value or security product (600). The security feature (160) is formed by at least one pattern (150). The method comprises the following method steps: (a) providing a subcarrier (200) having a colorant, wherein the colorant contains particles containing at least one dye and/or at least one pigment and a binder made from a polymer; (b) transferring at least one part of the colorant from the subcarrier (200) on a surface (310) of a polymer layer (300), forming a colorant layer (100) on the polymer layer (300), wherein the polymer layer (300) is produced from at least one material which is selected from a group comprising polycarbonate and polyethylene-terephtalate; and (c) locally introducing energy at least into a part of the colorant layer (100) in order to release the at least one dye and/or the at least one pigment from the particles, such that the pattern (150) is formed on the polymer layer (300).
