Title:
LAMINATED POLYESTER FILM
Document Type and Number:
Japanese Patent JP3951361
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To raise the adhesiveness with various kinds of paints or ink and an antistatic property under low moisture conditions, by having a laminated film formed by containing a specific wt.% or more sulfonated polyaniline on at least one surface of a polyester film, and specifying a contact angle of the laminated film surface with water in a specific range.
SOLUTION: Sulfonated polyanilin is contained in a laminated film by 4 wt.% or more. Besides, in the laminated film, a solid weight ratio between sulfonated polyaniline and resin is preferably 5/95-30/70, more preferably 10/90-25/75, and most preferably 10/90-20/80, and by being fallen in the range, a desired antistatic property is obtained and, moreover, its adhesiveness can be satisfied. A contact angle with water is preferably a degree of 65 or more or 85 or less, and more preferably, 70 or more and 75 or less, thereby raising the adhesiveness with various sorts of paints or ink and also adhesiveness under wet heat conditions.
