Abstract: PURPOSE: To obtain a transfer image excellent in the close adhesiveness with a sublimation type ink layer and not generating over-transfer by forming an easy adhesive layer by using an acrylic resin copolymerized with a compd. having a carboxyl group and/or a salt thereof within a specific wt.% range and a melamine crosslinking agent contained in amt. of specific % by wt. of the acrylic resin as main constitutional components. CONSTITUTION: A laminated polyester film is obtained by providing an easy adhesive layer on at least the single surface of a polyester film. The easy adhesive layer contains an acrylic resin copolymerized with 3-40wt.% of a compd. having a carboxyl group and/or a salt thereof and a melamine crosslinking agent as main constitutional components and the melamine crosslinking agent is contained in an amt. of 0.1-40 pts.wt. per 100 pts.wt. of the acrylic resin. The easy adhesive layer is provided by coating the polyester film with an adhesive before the completion of crystal orientation and subsequently completing the crystal orientation of the film by stretching and heat treatment.

Abstract: PURPOSE:To make antistatic properties and easy adherence compatible by reducing a P/C strength ratio by a secondary ion mass analyzing method of a depth direction of a laminated film toward a deep part of the film and setting hydrogen bonding component of surface free energy of the film to specific dyn/cm or less. CONSTITUTION:The laminated polyester film is provided with a laminated film having antistatic properties at least on one side surface of a polyester film. A P/C strength ratio measured by a secondary ion mass analyzing method in a depth direction of the film is reduced toward a deep part of the film (to the film side), i.e., increased toward a surface of the film, thereby developing excellent antistatic function. The hydrogen bonding component of surface free energy of the film is set to 13dyn/cm or less. Dispersion force component of the energy of the surface of the film is set to 20dyn/cm or more and less than 32dyn/cm, and further polarity force component is set to 3dyn/cm or more and less than 13dyn/cm, thereby improving adherent strength.
