Title:
EASILY FORMABLE POLYESTER FILM
Document Type and Number:
WIPO Patent Application WO/2002/006372
Kind Code:
A1
Abstract:
A polyester film characterized in that it comprises as a component a polyester (A) obtained from monomers including at least two glycol ingredients selected among ethylene glycol, butanediol, and propanediol, and that the polyester (A), in temperature-rising DSC, gives a crystal fusion temperature curve having substantially one peak and has a fusion peak temperature of 230°C or higher and the polyester (A) satisfies the following relationship (1). The film is suitable for use in producing formed, processed, or printed products or as a material film therefor. M / P $m(F) 1 (1) [In the relationship, M represents the concentration (mmol%) of a catalytic metal element remaining in the polyester (A) and P represents the amount (mmol%) of phosphorus remaining in the polyester (A).]
