PROTECTIVE FILM FOR A TOUCH SCREEN PANEL PROCESS AND MANUFACTURING METHOD THEREOF

摘要

The present invention relates to a heat resistant protective film for a touch screen panel process and a method for manufacturing the same. The heat resistant protective film for a touch screen panel process according to the present invention comprises a base material film, an adhesive layer, and a release film, wherein the adhesive layer is characterized by being manufactured from a copolymer comprising 1-48 parts by weight of a rigid acrylic monomer having a glass transition temperature of 0°C or more and 1-10 parts by weight of a cross-linking monomer for 50-90 parts by weight of a soft acrylic monomer having a glass transition temperature of 0°C of less. The heat resistant protective film for a touch screen panel process of the present invention composed by the same properly mixes soft and rigid monomers composing an adhesive and uses a cross-linking agent to improve the heat resistance of the adhesive used in an ITO heat resistant protective film for a TSP process, and to prevent inhibition of the increase of an adhesive force, adhesive transfer, bending of the ITO film, and an oxidation of an ITO layer after a heat treatment occurring in the TSP process to improve the productivity of the TSP process and reduce TSP defects.
