Abstract:
A wood decorative material coated with resin composite film, comprising:(i) a wood substrate, (ii) a heat bonding layer (A) disposed on a surface of the wood substrate, said heat bonding layer (A) formed from a heat bonding resin composition (a) comprising 100 parts by weight of a thermoplastic resin (a-1) composed of at least one member selected from the group consisting of polyolefins, polyolefin copolymers, polyesters, and polyamides, and 0.001 to 80 parts by weight of a tackifier resin (a-2), said heat bonding resin composition (a) having a melting point or softening temperature of 170Â° C. or below and exhibiting a melt flow rate (MFR) at 190Â° C. of 1 to 500 g/10 min, (iii) an adhesive layer (C) contacting the heat bonding layer (A) and comprising at least one adhesive component selected from the group consisting of an epoxy reactive adhesive, an isocyanate reactive adhesive, a polyester reactive adhesive, a polyethylene, and a resin prepared by a graft polymerization of a polyolefin or olefinic copolymer in the presence of maleic anhydride, acrylic acid or methacrylic acid, and (iv) a mar-proof surface layer (B) bonded to the wood substrate surface by means of the heat bonding layer (A) and adhesive layer (C), wherein (B) is formed from a biaxially oriented resin film, the resin having a melting point or softening temperature at least 20Â° C. higher than resin (a-1).
