摘要

PURPOSE: a kind of Photocurable composition has good machinability, and provide prevents from turning yellow under high temperature and humidity, to improve cure rate, and has excellent high temperature reliability. ;CONSTITUTION: a kind of Photocurable composition includes that polyurethane (methyl) acrylate oligomer chemical formula 1 indicates and photoinitiator. Carbamate (methyl) acrylate oligomer reacts and manufactures prepolymer and terminal isocyanate group, the culture of hydroxyl group (methyl) acrylate monomer. It forms prepolymer and reacts diethylene glycol (DEG), divalent polyalcohol removes diethylene glycol, and the isocyanates of excessively divalent. A kind of back light unit has the compound formed by next door including resin-type lightguide plate (140). ;The 2013 of copyright KIPO submissions
