Abstract

The present invention provides a shoe upper skin film for preventing dye migration, which comprises: a polyurethane skin or thermoplastic polyurethane (TPU) film having a color layer; and a thermoplastic polyurethane hot-melt film, wherein a film made of an ethylene-vinyl alcohol copolymer is formed between the TPU film and the hot melt film. Thus, when the skin film is bonded to a fabric, the dye of the fabric can be prevented from migrating to the skin film so that the color layer of the skin film can be stained from being stained.
