Document Type and Number:
Japanese Patent JP7435788
Kind Code:
B2
Abstract:
A resin composition including (A) an unsaturated polyester oligomer, (B) a radical polymerizable monomer, and (C) a photopolymerization initiator. The (A) unsaturated polyester oligomer includes a structure derived from a polyvalent alcohol component (a1) including 55-85 mol% neopentyl glycol per 100 mol% of the entire polyvalent alcohol component, a structure derived from a polybasic acid component (a2) including isophthalic acid and/or terephthalic acid, and a structure derived from an unsaturated dibasic acid component (a3) including maleic anhydride and/or fumaric acid, and includes, per 100 mol of the structure derived from the polyvalent alcohol component (a1), 30-60 mol of the structure derived from the polybasic acid component (a2) and 40-70 mol of the structure derived from the unsaturated dibasic acid component (a3).
