IN-MOLD TRANSFER FILM

摘要

The present invention provides an in-mold transfer film that has an excellent gloss feel, is free from occurrence of blocking in a process for production of the transfer sheet, and has such a function that the film can be smoothly released from its boundary after completion of the in-mold transfer process. The in-mold transfer film of the present invention comprises a polyester film and a release layer formed on one surface of the polyester film, in which the polyester film is in the form of a laminated polyester film comprising at least three layers whose outermost layers both are formed of the same polyester composition, a number of projections present on a surface of the polyester film which have a height of not less than 0.05 μm is not more than 1900/mm2, and a number of projections present on a surface of the polyester film which have a height of not less than 0.6 μm is not less than 25/mm2.
