Abstract

PURPOSE: To sub a photographic polyester film without causing nonuniform surfaces, insufficient adhesive strength, etc., by subjecting the polyester film to the corona discharge, and coating the film with a composition consisting of a compound having two or more ethyleneimino groups, a compound having two or more epoxy rings and a watersoluble high polymeric binder.
CONSTITUTION: One or both sides of a polyester film are subjected to the corona discharge, and then subbed with a composition consisting of (A) a compound having two or more ethyleneimino groups, e.g. a compound of formulaIor II (the group of formula III is ethyleneimine), (B) a compound having two or more epoxy rings, e.g. diglycerol polyglycidyl ether, and (C) a water-soluble high polymeric binder containing no active amino group, e.g. PVA or CMC, to form a subbing layer at a total coating weight (solid content) of 1g/m2. The coating weight of the respective components are preferably as follows: 1W100 mg/m2 total amount of the components (A) and (B) and 500mg/m2 or less component (C).
