Zusammenfassung:	SE MUESTRA UN ADHESIVO DE PELICULA FOTOCURABLE QUE COMPRENDE (I) UN MATERIAL FOTOCURABLE QUE TIENE ,COMO MEDIA, MAS DE UN GRUPO ACRILICO POR MOLECULA, Y AL MENOS 25% EN PESO DE DICHO MATERIAL ES UN ACRILATO DE URETANO, UN ACRILATO DE POLIESTER O UNA MEZCLA DE ACRILATO DE URETANO Y ACRILATO DE POLIESTER, (II) COMO COMPONENTE FORMADOR DE PELICULA SOLIDO PRINCIPAL, UN POLIVINILACETAL SOLIDO Y (II) UN FOTOINICIADOR PARA FOTOPOLIMERIZACION DE COMPUESTOS ACRILICOS. EL ADHESIVO DE PELICULA ES UTIL EN LA PRODUCCION DE LAMINADOS PORTADORES DE DATOS COMO CARTAS DE IDENTIDAD. A solid photocurable film adhesive comprising (I) a photocurable material having, on average, more than one acrylic group per molecule, at least 20% by weight of said material being a urethane acrylate, a polyester acrylate or a mixture of a urethane acrylate and a polyester acrylate, (II) as sole or major solid film-forming component, a solid polyvinylacetal and (III) a photoinitiator for photopolymerisation of acrylic compounds. The film adhesive is useful in the production of data-carrying laminates such as identity cards.
