Title:
PROCESS FOR PRODUCING PLASTIC LENS, FILM POSITIONING METHOD, AND COMPOSITE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2016/143379
Kind Code:
A1
Abstract:
This process for producing a plastic lens comprises: a step in which a first curable composition is placed on a shaping surface of a first mold substrate on which a surface of a lens is to be formed; a step in which the first curable composition is pressed and spread over the entire shaping surface by a film, and the first mold substrate is spaced apart from the film by a given distance, with the formed first curable composition layer interposed therebetween; a step in which the periphery of the first mold substrate, the periphery of the film, and the periphery of a second mold substrate having a shaping surface for forming the other surface of the lens are covered with a fixing member and fixed, and the second mold substrate is disposed so as to face the film spaced apart at a given distance therefrom; a step in which a second curable composition is injected into the space between the film and the second mold substrate; a step in which the first curable composition layer and the injected second curable composition are cured to form base layers on both surfaces of the film; and a step in which the fixing member, the first mold substrate, and the second mold substrate are removed and a plastic lens is taken out.
