Abstract: PURPOSE:To provide the titled protective film which is releasable even after long- term storage and does not damage the fabrication properties of a coated metal, by a method wherein a polyester-ether, a polyester, a polyolefin and a polycarbonate are blended together in a specified ratio. CONSTITUTION:(A) 10-70wt% of a polyester-ether having a m.p. of 90- 170 deg.C (e.g. a polytetramethylene terephthalate-isophthalate-polyoxytetramethylene glycol copolymer), (B) 10-70wt% of a polyester in which not less than 40mol% of the dicarboxylic acid component is terephthalic acid (e.g. a polyethlene terephthalate), (C) 1-30wt% of a polyolefin (e.g. a polyolefin or an ionomer), and (D) 0- 50wt% of a polycarbonate (pref. a polycarbonate resulting from the reaction of bisphenol A with phosgene) are blended together.

Abstract: PURPOSE:To prepare the title resin composition having excellent adhesivity to metal, moldability, and corrosion resistance, by blending a specific polyester, a modified polyolefin, and an ionomer. CONSTITUTION:A resin composition composed of (A) 20-70 wt% of a polyethylene terephthalate resin wherein >= 75 mol% of the dicarboxylic acid component is terephthalic acid (pref. the remaining part contains isophthalic acid), (B) 20-70 wt% of a polybutylene terephthalate resin wherein >= 60 mol% of the dicarboxylic acid component is terephthalic acid (pref. the remaining part contains isophthalic acid), (C) 5-30 wt% of a modified polyolefin such as a copolymer obtained by grafting an alpha,beta-ethylenic unsaturated dibasic acid (or its anhydride, ester, amide, etc.) to a polyolefin, and (D) 0-25 wt% of an ionomer (e.g. Surlyn A, product of DuPont), wherein (C) + (D) is 5-30 wt%.

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

Abstract: PROBLEM TO BE SOLVED: To provide a polyester film for a tacky label which meets adhesive properties with various kinds of printing layers for a tacky label and a tacky label using this film. SOLUTION: The polyester film for a tacky label has a laminated film comprising two kinds of polyester resins having different glass transition points, formed on at least one of the sides of a polyester film. The two kinds of the polyester resins are each constituted of a polyester resin (A) with a glass transition point of 60 to 100 deg.C and a polyester resin (B) with a glass transition point of 0 to 60 deg.C. In addition, the polyester resin (B) contains 65 to 95 mol% of isophthalic acid as an acid component or 50 to 95 mol% of diethylene glycol as a diol component. Also the tacky label using the polyester film is provided.

Abstract: PROBLEM TO BE SOLVED: To provide a laminated polyester film capable of satisfying the adhesiveness with various articles to be coated incapable of being obtained heretofore. SOLUTION: The laminated polyester film is obtained by forming a laminated film consisting of two kinds of polyester resins having different glass transition points on at least the single surface of a polyester film. Two kinds of polyester resins consist of a polyester resin (A) with a glass transition point of 60-100 deg.C and a polyester resin (B) with a glass transition point of 0-60 deg.C. The polyester resin (B) contains 65-95 mol % of isophthalic acid as an acid component and/or contains at least 50-95 mol % of diethylene glycol as a diol component.

Abstract: PROBLEM TO BE SOLVED: To prepare a recycled polyester film reduced in discoloration. SOLUTION: The recycled polyester film comprises a non-crosslinkable copolymerized resin comprising as copolymerizing components at least styrene and an acrylate and having a thermal weight loss temperature (a temperature where a certain weight loss is observed) of at least 350 deg.C. The recycled polyester film can be manufactured from a laminated polyester film, as a material to be recycled, comprising a polyester film and a resin layer which is formed on at least one surface of the polyester film and composed of the non- crosslinkable copolymerized resin.
