Abstract

Novel multi-layer laminate articles of improved adhesion strength comprising at least two layers including a polyester resin layer and a layer of an epoxy group-containing olefin polymer or an olefin polymer composition comprising the epoxy group-containing polymer, are described. The epoxy group-containing olefin polymer is a copolymer of an olefin and an unsaturated glycidyl group-containing monomer or a copolymer of an olefin, an unsaturated glycidyl group-containing monomer and an ethylenically unsaturated monomer.

Claims

1. A multi-layer laminate article which comprises at least two layers including a polyester resin layer and a layer of an epoxy group-containing olefin polymer or an olefin polymer composition comprising the epoxy group-containing olefin polymer, the epoxy group-containing olefin polymer being a copolymer containing an unsaturated glycidyl group containing monomer in the main chain prepared by subjecting 50-99.95 wt% of ethylene, 0.05-50 wt.% of an unsaturated glycidyl group-containing monomer and up to 49.95% wt.% of an ethylenically unsaturated monomer to polymerization.

2. A multi-layer article according to claim 1, wherein the the unsaturated glycidyl group-containing monomer is glycidyl methacrylate or glycidyl acrylate.

3. A multi-layer article according to claim 1, wherein the ethylenically unsaturated monomer is at least one monomer selected from the group consisting of olefins, vinyl esters, alpha, beta-ethylenically unsaturated carboxylic acids and derivatives thereof.

4. A multi-layer article according to claim 3, wherein the ethylenically unsaturated monomer is a member selected from the group consisting of vinyl acetate, methacrylic acid, acrylic acid, methyl methacrylate, methyl acrylate, ethyl methacrylate, ethyl acrylate, butyl methacrylate, butyl acrylate, maleic acid and maleic anhydride.

5. A multi-layer article according to claim 1, wherein said article is a three-layer structure comprising the polyester resin layer as a first layer, the layer of the epoxy group-containing olefin polymer or the olefin polymer composition as a second layer comprising the epoxy group-containing olefin polymer, and a third layer arranged in this order.

6. A multi-layer article according to claim 5, wherein said third layer is of at least one member selected from the group consisting of thermoplastic resins, thermosetting resins, rubbers, paper, wood, cloths, metals and glass.

7. A multi-layer article according to claim 6, wherein the thermoplastic resin is at least one member selected from the group consisting of olefin resins, saponified ethylene-vinyl acetate copolymers, polyamide resins, polycarbonate resins, polyvinyl chloride resins, polyvinylidene chloride resins, polyester resins, polyacrylonitrile resins, polystyrene resins, polyvinyl alcohol resins, ABS resins, polymethyl methacrylate, fluorocarbon resins, polyimide resins, polyamide-imide resins, polyether.ether ketone resins, polyether sulfone resins, polysulfone resins, polyphenylene oxide resins, polyphenylene sulfide resins and polyacetal resins and blend thereof.

8. A multi-layer article according to claim 7, wherein said article has a three-layer structure consisting of a polyester resin layer, a layer of ethylene/glycidyl methacrylate copolymer, and a layer of a saponified ethylene-vinyl acetate resin.
