Abstract:
[Problem to be solved] This invention provides a laminated adhesive film excellent in the adhesive property to a metal layer, especially excellent in the adhesive property to a metalized layer, the adhesive property after a heat and wet test and the adhesive property after solvent tests using various chemicals. [Solution] A laminated adhesive thermoplastic resin film, comprising a laminated layer containing two polyester resins different from each other in glass transition temperature and a melamine-based crosslinking agent (C) as main components and having a surface energy of 48 to 55 mN/m, formed at least on one surface of the thermoplastic resin film, wherein the glass transition temperature of the polyester resin (A) higher in glass transition temperature is 110°C or higher; the glass transition temperature of the polyester resin (B) lower in glass transition temperature is 60°C to lower than 110°C; and the amount of the melamine-based crosslinking agent (C) is 75 to 200 parts by weight per 100 parts by weight in total of said two polyester resins.
Abstract:
The present invention relates to a laminate film comprising a thermoplastic resin film and a laminate film provided at least one side of the thermoplastic resin film, the laminate film comprising an acrylic urethane copolymer resin (A), a polyester resin (B) and a cross-linking agent (C), and the cross-linking agent (C) being an isocyanate-type cross-linking agent and/or a carbodiimide-type cross-linking agent and contained in an amount of 5 to 70 parts by weight based on 100 parts by weight of the sum of the acrylic urethane copolymer resin (A) and the polyester resin (B). The invention provides a laminate film that is excellent in initial adhesion, adhesion after wet heat aging and adhesion after irradiation with UV ray, and is also excellent in transparency and coating appearance.

PROBLEM TO BE SOLVED: To provide a laminated polyester film which can satisfy adhesion to various coating materials and is excellent in adhesion after the passage of time, and to provide a method for producing the film. SOLUTION: In the laminated film, a laminated film containing a polyester resin as a main component is formed at least on one side of a polyester film. The N/C value of the surface of the laminated film measured by an X-ray photoelectron spectroscopy method is 0.005-0.5. The laminated polyester film can be produced by applying discharge processing to the laminated film formed at least on one side of the polyester in a nitrogen atmosphere. COPYRIGHT: (C)2003,JPO

PROBLEM TO BE SOLVED: To provide a laminated polyester film excellent in adhesion to each sort of coating layer and in blocking resistance and scratch resistance. SOLUTION: In the laminated polyester film, a laminated film constituted of two kinds of polyester resins being different in a glass transition point and made to contain wax is formed at least on one side of a polyester film. The two kinds of polyester resins comprise a polyester resin (A) of which the glass transition point is 60-100°C, and a polyester resin (B) of which the glass transition point is 0 to below 60°C. The polyester resin (B) contains an isophthalic acid of 65-95 mol% as an acid component or a diethylene glycol of 50-95 mol% as a diol component. COPYRIGHT: (C)2003,JPO
Abstract:
PROBLEM TO BE SOLVED: To provide a laminated polyester film which is improved in adhesion to various coats and excellent in adhesion after passage of time, and to provide a method for producing the film. SOLUTION: In the laminated polyester film, a laminated film containing an acrylic resin as a main component and functional groups having nitrogen atoms is formed at least on one side of a polyester film. The N/C value of the surface of the laminated film measured by an X-ray photoelectron spectroscopy method is 0.01-0.1. The laminated polyester film can be produced by applying discharge processing to the laminated film formed at least on one side of the polyester film in a nitrogen atmosphere. COPYRIGHT: (C)2003,JPO
