Title:
RESIN COMPOSITION FOR OPTICAL THREE-DIMENSIONAL MODELING
Document Type and Number:
WIPO Patent Application WO/2020/235628
Kind Code:
A1
Abstract:
The present invention provides a resin composition for optical three-dimensional modeling, which is reduced in odor during optical three-dimensional modeling, while having excellent forming accuracy, and which enables a cured product thereof to have excellent strength, toughness and color. The present invention relates to a resin composition for optical three-dimensional modeling, which contains (A) a polymerizable monomer, (B) a photopolymerization initiator and (C) an organic peroxide, wherein: the polymerizable monomer (A) contains (A-1) a (meth)acrylic acid ester compound having a viscosity of 1,000 mPa∙s or less and a normal pressure boiling point of 270°C or more and/or (A-2) a (meth)acrylamide compound having a viscosity of 1,000 mPa∙s or less and a normal pressure boiling point of 200°C or more; and the photopolymerization initiator (B) is composed of at least one compound that is selected from among (bis)acylphosphine oxides, α-hydroxy ketone compounds, α-amino ketone compounds, benzoin alkyl ether compounds, thioxanthones, ketals, α-diketones and anthraquinones.
