This invention relates to an imaged receptor laminate (10), comprising: a thermoplastic core layer (12) having a first side and a second side; a thermoplastic skin layer (14) overlying said first side of said core layer (12), said skin layer (14) comprising a major amount of a thermoplastic copolymer of terpolymer derived from ethylene or propylene and a functional monomer selected from the group consisting of alkyl acrylate, acrylic acid, alkyl acrylic acid, vinyl acetate and combinations of two or more thereof, said skin layer (14) having a melting point in the range of about 50 ~C to about 120 ~C, said core layer (12) having a melting point that is higher than the melting point of said skin layer (14); and an electrostatically formed and developed image (22) adhered to said skin layer (14). This invention also relates to a process for making the foregoing imaged receptor laminate (10).

La présente invention concerne un stratifié récepteur d'image (10) qui comprend une couche centrale thermoplastique (12) présentant un premier côté, une couche superficielle thermoplastique (14) superposée audit premier côté de la couche centrale (12), ladite couche superficielle (14) contenant une quantité prépondérante d'un copolymère ou terpolymère thermoplastique à base d'éthylène ou de propylène et un monomère fonctionnel sélectionné dans le groupe constitué par un acrylate d'alkyle, un acide acrylique, un acide acrylique d'alkyle, un acétate de vinyle ou des combinaisons d'un ou plusieurs desdits composés. La couche superficielle (14) présente un point de fusion compris entre environ 50 ·C et 120 ·C et inférieur au point de fusion de la couche centrale (12). Le stratifié comprend aussi une image (22) formée et traitée par un procédé électrostatique et collée à la couche superficielle (14). L'invention concerne en outre un procédé de fabrication dudit stratifié récepteur d'image (10).
