Document Type and Number:
WIPO Patent Application WO/2015/068820
Kind Code:
A1
Abstract:
[Problem] To provide a resin composition for optical three-dimensional molding which makes it possible to produce a three-dimensional molded article exhibiting a low degree of yellowing, high light transmittance, low water and moisture absorption, and excellent impact resistance. [Solution] A resin composition for optical three-dimensional molding containing a radical polymerizable organic compound (A), a cationic polymerizable organic compound (B), a radical polymerization initiator (C), and a cationic polymerization initiator (D), the resin composition containing: polyalkylene glycol di(meth)acrylate (A-1) having a mean molecular weight of 300-2000 as part of the radical polymerizable organic compound (A); an alicyclic diglycidyl ether compound (B-1) represented by general formula (B-1) (In the formula, R1 represents a hydrogenated bisphenol A residue, a hydrogenated bisphenol E residue, a hydrogenated bisphenol F residue, a hydrogenated bisphenol AD residue, a hydrogenated bisphenol Z residue, a cyclohexane dimethanol residue, or a tricyclodecane dimethanol residue.) as part of the cationic polymerizable organic compound (B); and an oxetane compound (B-2) as another part of the cationic polymerizable organic compound (B).
