POLYESTER RELEASE FILM FOR POLARIZER

摘要

A polyester release film for a polarizer is provided to improve the adhesion between a polyester base film and a silicone release coating layer and to minimize the inferiority due to the removing of a release film by enhancing the aging stability of releasing force. A polyester release film for a polarizer comprises a polyester base film; a primer layer which is formed by coating, drying and crosslinking a primer coating solution containing a silane coupling agent represented by Y-R-Si(X) on the one surface of the base film; and a silicone release coating layer which is formed by coating, drying and crosslinking a coating solution containing the polydimethylsiloxane represented by the formula 2 and the curing silicone resin of hydrogen silane represented by the formula 3, wherein Y is a vinyl group, an epoxy group, an amino group or a mercapto group; R is a direct bond or a C1-C6 alkylene group; X is a C1-C6 alkoxy group; 1.0<=o/m<=1.4; 100<=m+n<=5,000; and 10<=o+p<=200.
