<P>PROBLEM TO BE SOLVED: To provide an adhesive releasing polyester film for in-mold transfer materials which can easily process a hard coat layer as an adhesive releasing layer on the adhesive releasing layer when providing the adhesive releasing layer on at least one surface of a film used for a substrate of an in-mold transfer foil, is easily peelable from the hard coat layer after transferring, has adhesive releasing properties such that a foil run-off phenomenon does not occur when slit-processing at a width matching to the dimension of a material to be transferred, is excellent in molding followability to the transfer layer such as a printing layer or adhesion layer which is laminated on the layer including the hard coat layer, and is useful as the substrate film of the in-mold transfer foil. <P>SOLUTION: There is provided the adhesive releasing polyester film for the in-mold transfer materials which has the adhesive releasing layer on at least one surface of a polyester film, and in which the adhesive releasing layer contains (A) a fluorine-based polymer having a glass transition point of ≥-40°C but ≤20°C, (B) an urethane-based polymer having a glass transition point of ≥-60°C but ≤10°C and (C) a crosslinking agent, and a peel strength of the hard coat layer to the adhesive releasing layer is ≥0.2 N/mm but ≤0.4 N/mm, and further a surface strength of the adhesive releasing layer measured by a microhardness meter is ≥0.5 to ≤4.5 GPa. <P>COPYRIGHT: (C)2012,JPO&INPIT |
