Title:
METHOD FOR PRODUCING PLASTIC LENS
Document Type and Number:
WIPO Patent Application WO/2008/001706
Kind Code:
A1
Abstract:
Disclosed is a method for producing a plastic lens having reflow heat resistance at 260˚C, which is characterized in that a photosensitive resin composition containing a specific resin and a photopolymerization initiator is molded into a lens shape. The resin is obtained by mixing one or more compounds (a) selected from the group consisting of (CH3O)3-Si-(CH2)3-O-CO-C(CH3)=CH2, (CH3O)3-Si-(CH2)3-O-CO-CH=CH2, (CH3O)3-Si-(CH2)x-CH=CH2 (wherein X is 1 or 2), (CH3O)2-Si(CH3)(CH2)3-O-CO-C(CH3)=CH2, (CH3O)2-Si(CH3)(CH2)3-O-CO-CH=CH2 and (CH3O)2-Si(CH3)-(CH2)x-CH=CH2 (wherein X is 1 or 2), with a compound (b) represented by (C6H5)2-Si-(OH)2 such that 50-150 moles of the compounds (a) is mixed per 100 moles of the compound (b), and then polycondensing the mixture at 40-150˚C for 0.1-10 hours in the presence of a catalyst.
