Field: Macromolecular chemistry, polymers (Chemistry)
Classification: CPC C  B | IPC C

Claim 0:
1. A composition for optical stereolithography, comprising:
(A) a diallyl phthalate-based polymer;
(B) radical polymerizable compounds having a methacrylic group and/or an acrylic group;
(C) a radical polymerization initiator; and
(D) a sensitizer,
wherein the (B) radical polymerizable compounds having a methacrylic group and/or an acrylic group comprises at least
(B1) a radical polymerizable compound of an epoxy (meth)acrylate having a methacrylic group and/or an acrylic group, and/or
(B2) a radical polymerizable compound of a dioxane (meth)acrylate having a methacrylic group and/or an acrylic group,
wherein the composition for optical stereolithography contains:
0.5 to 10% by mass of the (A) diallyl phthalate-based polymer;
5 to 43% by mass of a total content of the (B1) and (B2) radical polymerizable compounds,
20 to 95% by mass of a radical polymerizable compound in the (B) radical polymerizable compounds other than the (B1) and (B2) radical polymerizable compounds,
0.1 to 5% by mass of the (C) radical polymerization initiator, and
0.1 to 5% by mass of the (D) sensitizer.
