De Winter Walter Frans, Van Paesschen August Jean, Van Gossum Lucien Janbaptist, Van Thillo Etienne Adrianus, Marien August Marcel: Aqueous copolyester dispersions suited for the subbing of polyester film, subbed polyester film and photographic materials containing a subbed polyester base.. Agfa Gevaert, June 3, 1981: EP0029620-A1 (28 worldwide citation)

An aq. dispersion contains a copolyester comprising recurring ester gps. derived from ethylene glycol and a mixt. of 20-60 mole % isophthalic acid, 6-10 mole % sulphoisophthalic acid (having the sulpho gp. in salt form) and the remainder terephthalic acid. The copolyester has a glass transition temp ...

Van Paesschen August Jean, Van Gossum Lucien Janbaptist, Priem Jan Jozef: Adhesion of hydrophilic layers on polyester film. Agfa Gevaert, Daniel William J, October 7, 1975: US3911172 (7 worldwide citation)

The adhesion of hydrophilic layers on a dimensionally stable polyester film support is improved by applying after longitudinal stretching of the polyester film a single adhesive layer thereon. The thus covered polyester film is stretched in transverse direction and heat-setted at 180.degree.-220.deg ...
