摘要

PURPOSE: A photo curable resin composition is provided which is useful for fabricating optical parts such as a backlight for liquid crystal displays. CONSTITUTION: A photo curable resin composition comprises (a) a compound shown by the following formula (1), wherein R1 and R2 individually represent a hydrogen atom or methyl group, m and n are integers of which the total is 0 or 1-6, and X represents a bromine or chlorine atom, or a urethane (meth)acrylate obtained by the reaction of the compound of the formula (1) and an organic isocyanate, (b) a (meth)acrylate which possesses 3 or more (meth)acryloyl groups in the molecule, and (c) a photopolymerization initiator. Also optical parts are made from the photo curable resin composition.
