<p><P>PROBLEM TO BE SOLVED: To obtain a dummy can for a vending machine excellent in heat resistance, free from the shift of a pattern due to ink adhesion or thermoforming and also excellent in processability, recyclability and economical efficiency. <P>SOLUTION: This polyester laminate is constituted by laminating layers, which comprise a composition (B) prepared by compounding 100-10,000 ppm of particles, of which the secondary particles have a mean particle size of 0.5-20μm, and 0.01-2.0 wt.% of an ester product comprising a polyol having at least four hydroxyl groups and a 12 or above C aliphatic monocarboxylic acid with PBT with an intrinsic viscosity of 0.40-0.70, on both sides of a base material layer comprising a composition (A) with an intrinsic viscosity of 0.55-1.0 comprising 40-90 wt.% of PET and 10-60 wt.% of PBT. The glass transition temperature of the layer (A) is 80°C or above, the difference between the glass transition temperatures of the layer (B) and the layer (A) is 35°C or below and the thickness of the layer (B) is 5-35μm. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
