Abstract

PURPOSE:To enhance the adhesive strength to a polarizing film and to improve the dimensional stability and durability of a polarizing plate by subjecting the surface of a protective film consisting of a cellulosic film to a corona treatment. CONSTITUTION:The polarizing plate is produced by sticking the polarizing film formed by adsorbing a dichromatic dye (e.g.: iodine) on a PVA film and the protective film consisting of the cellulosic film (A) by using an adhesive agent (B). The film which is subjected to the corona surface treatment on at least the polarizing film side surface on the film A is used. The above-mentioned corona treatment is preferably treated under the conditions of 20-400W.min/m<2> conditions by a corona treating machine having multi-knife electrodes. The film A is a cellulose triacetate or diacetate film and the adhesive agent B is an urethane adhesive agent of a solventless type.
