CURABLE RESIN COMPOSITION, CURED PRODUCT, AND THREE-DIMENSIONAL OBJECT

Document Type and Number:

WIPO Patent Application WO/2020/066736

Kind Code:

A1

Abstract:

The present invention provides a curable resin composition comprising a polyester resin (A) having (meth)acryloyl groups, and a monofunctional (meth)acrylate compound (B1) and/or a bifunctional (meth)acrylate compound (B2), and is characterized in that the average number of functional groups of the (meth)acryloyl groups of the polyester resin (A) is in the range of 1.5-3, and the contained amount of the polyester resin (A) in the curable resin composition is 50 mass% or more. This curable resin composition has low viscosity, and a cured product obtained from this curable resin composition has excellent mechanical properties, and therefore, can be suitably used as a resin composition for optical three-dimensional shaping.
