Abstract
Official abstract text for this publication.
The present invention provides a composition for optical three-dimensional modeling that offers desirable shape accuracy in optical three-dimensional modeling, and that provides desirable transparency and mechanical characteristics upon being cured. The present invention relates to a composition for optical three-dimensional modeling comprising a polymerizable monomer (a), an ultraviolet-absorbing inorganic particle (b), and a photopolymerization initiator (c).
First claim
Opening claim text (preview).
1 . A composition for optical three-dimensional modeling, comprising: a polymerizable monomer (a); an ultraviolet-absorbing inorganic particle (b); and a photopolymerization initiator (c). 2 . The composition for optical three-dimensional modeling according to claim 1 , wherein the composition further comprises an organic ultraviolet absorber (d). 3 . The composition for optical three-dimensional modeling according to claim 2 , wherein the organic ultraviolet absorber (d) comprises a benzotriazole compound. 4 . The composition for optical three-dimensional modeling according to claim 1 , wherein the polymerizable monomer (a) comprises a (meth)acrylate polymerizable monomer and/or a (meth)acrylamide polymerizable monomer. 5 . The composition for optical three-dimensional modeling according to claim 1 , wherein the polymerizable monomer (a) comprises an aliphatic difunctional (meth)acrylate polymerizable monomer, or an aromatic difunctional (meth)acrylate polymerizable monomer. 6 . The composition for optical three-dimensional modeling according to claim 1 , wherein the polymerizable monomer (a) comprises a monofunctional (meth)acrylamide polymerizable monomer. 7 .
