Photocurable resin composition and optical material

摘要

The invention relates to a photocurable resin composition comprising the following components: a) a urethane (meth)acrylate produced by reacting compounds which at least comprise a polyether diol compound with a number average molecular weight of 200 to 500 containing a structure selected from the group consisting of a tetramethyleneoxy structure, a propyleneoxy structure, and a 1,2-butyleneoxy structure in the molecule, an organic polyisocyanate compound, and a hydroxyl group-containing (meth)acrylate, b) a monofunctional (meth)acrylate and c) a photoinitiator. The invention further relates to optical parts and products like projection TV's.
