Abstract
Abstract A plastic molding comprising a plastic substrate and a decorative film or sheet which has an outermost layer of fluororesins coated at its one surface with a vaporized metal layer, an intermediate layer of ethylene-acrylic acid copolymeric resins laminated on the metal layer, and an innermost layer of backing resins which is adhered to the intermediate layer by an adhesive layer. The decorative film or sheet is molten to be adhered onto the plastic substrate, so that the backing resin layer comes into contact with the plastic base.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
82 words
A plastic molding, comprising: a plastic substrate and a decorative film or sheet having an outermost protecting layer of fluoroplastics being metallized on one surface, an intermediate layer of an ethylene-acrylic acid copolymer laminated on the metal layer, and an innermost backing layer adhered to the intermediate layer by an adhesive layer, said backing layer of said decorative film or sheet being molten to be adhered onto the plastic substrate, so that the backing layer comes into contact with the plastic substrate.
Claim 2
Dependent Claim
82 words
A plastic molding, comprising: a plastic substrate and a decorative film or sheet having an outermost protecting layer of fluoroplastics being metallized on one surface, an intermediate layer of an ethylene-acrylic acid copolymer laminated on the metal layer, and an innermost backing layer adhered to the intermediate layer by an adhesive layer, said backing layer of said decorative film or sheet being molten to be adhered onto the plastic substrate, so that the backing layer comes into contact with the plastic substrate.
Claim 3
Dependent Claim
42 words
A plastic molding according to claim 1, further comprising another intermediate layer of ionomer plastics between the intermediate layer of ethylene-acrylic acid copolymers and the backing layer, so that the latter is adhered onto the ionomer intermediate layer by the adhesive layer.
Claim 4
Dependent Claim
39 words
A plastic molding according to claim 1, wherein said outermost fluoroplastic layer 21 is made of a transparent film of a material selected from polytetrafluoroethylene, tetrafluoroethylene-perfluoroalkylvinylether copolymer, tetrafluoroethylene-hexa-fluoropropylene copolymer, polychlorotrifluoroethylene, tetrafluoroethylene-ethylene copolymer, chlorotrifluoroethylene-ethylene copolymer, polyvinylidene fluoride, and polyvinyl fluoride.
Claim 5
Dependent Claim
23 words
A plastic molding according to claim 1, wherein said ethylene-acrylic acid copolymers are made from copolymers of ethylene and ethylenically unsaturated carboxylic acid.
Claim 6
Dependent Claim
16 words
A plastic molding according to claim 4, wherein said ethylenically unsaturated carboxylic acid is acrylic acid.
Claim 7
Dependent Claim
16 words
A plastic molding according to claim 4, wherein said ethylenically unsaturated carboxylic acid is methacrylic acid.
