Disclosed is a curable resin composition which has excellent optical properties, heat resistance, transparency, low water absorbability, and mold release properties when molding, and reduces the occurrence of flash from molds. Also disclosed are a cured article thereof and an optical article. The curable resin composition comprises a component (A): a soluble polyfunctional (meth)acrylic acid ester copolymer which is obtained by copolymerizing components including (a) a monofunctional (meth)acrylic acid ester having an alicyclic structure, (b) a difunctional (meth)acrylic acid ester, and (c) 2,4-diphenyl-4-methyl-1-penten, has a reactive (meth)acrylate group derived from (b) in a side chain and a structural unit derived from (c) at an end, has a Mw of 2000 to 20000, and is soluble in an organic solvent, a component (B): a polyfunctional (meth)acrylate, and a component (C): an initiator, wherein the blending amounts (weight ratio) of the respective components are as follows: (B)/(A) = 5 to 250/100, and (C)/[(B)+(A)] = 0.1 to 10/100. |
