Document Type and Number:
WIPO Patent Application WO/2011/025169
Kind Code:
A2
Abstract:
The present invention relates to a method for manufacturing an acrylic film and to an acrylic film manufactured by same, the method comprising: a first step of coating an acryl-based resin syrup; and a second step of hardening the acryl-based resin syrup coated in the first step by irradiating ultraviolet rays. According to the present invention, an excellent film having low thickness deviation and thickness precision may be provided. In addition, defects in the film such as fish eyes and uneven distribution of physical properties in the vertical and horizontal directions may be kept to a minimum. Consequently, the film according to the present invention can be applied to various industrial sheets such as protective films for various semiconductor processes, pressure-sensitive adhesives or adhesives for optical products and pressure-sensitive adhesives or adhesives for electronic components, or to laminated products.
