摘要： A sandwich of sheet material and a plastic film on at least one side thereof is laminated together by advancing the sandwich in one direction between an opposed pair of rigid heating and pressure plates having mutually facing planar surfaces for contacting the sides of the sandwich. The plates of the pair being biased together under a pressure which increases in the direction of the sandwich advance while the pressure level across the plates transverse to the direction of advance at any locus along the plates is substantially uniform, and passing the thus heated and compressed sandwich between the nip of a pair of pressure rollers to complete welding of the sandwich together.

摘要： Process for the production of a laminated article including a sheet support bearing a silver image produced by the silver complex diffusion transfer process in a layer containing developement nuclei, wherein such supported image is heat-laminated with a protective thermoplastic resin layer of sheet that covers it. The heat-lamination of the nuclei-containing layer with the silver image therein takes place in the presence of at least one of certain heterocyclic black-toning agents which are effective to prevent degradation of the neutral black coloration and density loss of the silver image as a result of heat-lamination.

摘要： In a laminated product wherein at least one supported information-containing hydrophilic colloid layer is adhesively bonded on at least one of its surfaces to a protective hydrophobic resin sheet, improved adherence is achieved by using as the bonding adhesive a cationic crosslinked polymer obtained by:a) condensing a polyalkylenepolyamine containing at least two primary amino groups and at least one secondary or tertiary amino group with a dicarboxylic acid to form a polyamidoamine,b) subjecting the resultant polyamidoamine to a graft reaction in the presence of an acid catalyst with an alkene-1,2-imine, andc) crosslinking the resultant graft polymer with an epihalohydrin, an Alpha-Omega dihalohydrin ether or the ether compound obtained by reaction of epichlorohydrin with a water-soluble polyalkyleneoxide to form the water-soluble cationic polymer. With this adhesive bond, a tamper-proof seal can be obtained between the information-containing colloid layer and the hydrophobic resin protective sheet.
