    Abstract: PURPOSE:A film freed from a dewing phenomenon occurring in a high-humidity atmosphere or from a temperature difference, comprising a hydrophilic polyamide or polyester. CONSTITUTION:A hydrophilic polyamide or polyester film having an equilibrium moisture content of above 5% under conditions of 20 deg.C and 65% RH. Examples of the above films include a polyamide (or polyester) film containing above 2.7X 10 g eq./g carboxyl group substituted with an alkali metal or ammonium salt, and a polyamide (or polyester) film containing about 5wt% hydrophilic compound compatible with the film polymer, e.g., polyvinylpyrrolidone.
