| 摘要 |
The present invention relates to an optical polyester film having excellent anti-blocking property and, more specifically, to an optical polyester film having excellent anti-blocking property which has excellent adhesion, moistureproof adhesion, and optical characteristics such as transmissivity, haze characteristics, etc. and is capable of preventing a blocking phenomenon which refers to adhesion occurring among coating layers by moisture permeation or by the combination between unreactive molecules in a coating layer. The optical polyester film having excellent anti-blocking property according to the present invention comprises a primer layer formed by coating a coating solution on at least one surface of a polyester base film, the coating solution containing polyurethane resin, an isocyanate hardener, an oxazoline hardener, a surfactant and an aqueous dispersion of particles. |
