Abstract

A foil-decorating sheet (4) comprised by a laminated film of two or more kinds of films which is to be set in an injection mold (5, 6) for being integrally bonded to a surface of a molding resin (10), wherein after a foil-decorating is made, a bonding surface-side film (3) of the laminated film which is bonded to the molding resin (10) has a peel strength of not less than 1 kgf/inch width at least at an interface between the surface film (3) of the laminated film bonded to the molding resin (10) and the molding resin (10), and wherein at least a transparent acrylic film (1) is laminated on the bonding surface-side film (3) bonded to the molding resin, with a decorative layer (2) formed between the bonding surface-side film (3) bonded to the molding resin and the acrylic film (1).

A foil-decorating sheet comprising a laminated film of two or more different films which is to be set in an injection mold for being integrally bonded to a surface of a molding resin, wherein after a foil-decorating sheet is made, a bonding surface-side film of the laminated film which is on a side of a surface to be bonded to the molding resin has a peel strength of not less than 1 kgf/inch width at least an interface between the molding resin and the bonding surface-side film of the laminated film bonded to the molding resin, and wherein at least a transparent acrylic film formed by extrusion which comprises acrylic resin as its main component is laminated on the bonding surface-side film bonded to the molding resin, with a decorative layer formed between the acrylic film and the bonding surface-side film bonded to the molding resin,

wherein the bonding surface-side film of the laminated film which is bonded to the molding resin is a polypropylene film and
wherein the polypropylene film is formed of a non-crystalline or low crystalline polypropylene resin having a crystallinity of 50% or less.
