Abstract (en)
[origin: WO2021013480A1] The invention relates to a method and a hot-melt adhesive for producing a value- or security document (11) consisting of multiple layers (3, 5), and to a value- or security document, according to which method: a hot-melt adhesive (4) made from a latent reactive adhesive substance is applied in liquid form, or is supplied as a film, to at least a first or second layer (3, 5), or to both layers (3, 5) and the at least two layers (3, 5) together with the hot-melt adhesive layer (4) provided therebetween are combined to form a composite body (6); and the latent reactive adhesive substance is heated and the layers (3, 5) are bonded together by subsequent cooling, a curing time of the hot-melt adhesive being accelerated by at least one extender introduced into the latent reactive adhesive substance.
