Abstract (en)
[origin: WO2018054765A1] The invention relates to a method for producing a security or valuable product, particularly a security or valuable document, with a substrate and a diffractive security element that is directly connected to the substate by means of an adhesive layer. The invention also relates to a security or valuable product produced by said method. The invention comprises the following steps: (i) a hot-melt adhesive and a latent-reactive adhesive are applied to a) a region of the substrate provided for the security element and/or b) the security element, either the hot-melt adhesive and latent-reactive adhesive being applied as a mixture or the hot-melt adhesive and the latent-reactive adhesive being applied separately from each other in sections, where an application temperature Ta1 of the hot-melt adhesive is lower than an application temperature Ta2 of the latent-reactive adhesive, and Ta1 ≤ T1 ≤ Ta2 is valid for a temperature T1 during the application; (ii) the security element is placed on the substrate; and (iii) heating is carried out to a temperature T2, where T2 ≥ Ta2.
