A laminated product, wherein a hydrophilic colloid layer is adhered by an adhesive coating to a hydrophobic resin web or foil, characterized in that said adhesive coating contains the condensation product of a polyalkylenepolyamine containing at least two primary amino groups and at least one secondary or tertiary amino group with a dicarboxylic acid which condensation product being a polyamidoamine has been grafted by reaction with an alkene-1,2-imine in the presence of an acid catalyst, and has been transformed into a cationic crosslinked polymer by allowing to react the obtained grafted polymer with a bifunctional crosslinking agent being an epihalohydrin or an Alpha-Omega-dihalohydrinether or the ether compound obtained by reaction of epichlorohydrin with a watersoluble polyalkyleneoxide, The laminated product is in one application a tamperproof identification document. |
