Abstract:
A laminate polyester film to be laminated onto metal plate and molded, which comprises:(A) a first layer made from copoly(ethylene-terephthalate/isophthalate) having a melting point of 205 to 250.degree. C., and(B) a second layer made from a polyester (i) comprising ester units of an aromatic dicarboxylic acid component, an aliphatic dicarboxylic acid component and aliphatic diol components, the aromatic dicarboxylic component being terephthalic acid, a combination of terephthalic acid and isophthalic acid, a combination of terephthalic and phthalic acid, or a combination of terephthalic acid, isophthalic acid and phthalic acid, the aliphatic dicarboxylic acid component being one member selected from the group consisting of adipic acid and a combination of adipic acid and sebacic acid, and the aliphatic diol components being ethylene glycol, diethylene glycol, and tetramethylene glycol, (ii) containing a titanium compound soluble in the polyester in an amount of 30 to 200 ppm in terms of elemental titanium and (iii) having one or two melting point(s) in the range of 170 to 245.degree. C., and(C) which has a maximum peak temperature of loss elastic modulus of higher than 47.degree. C. and 85.degree. C. or lower.
