Title:
INK COMPOSITION FOR THREE-DIMENSIONAL MODELING, INK SET, AND METHOD FOR PRODUCING THREE-DIMENSIONAL MODEL
Document Type and Number:
WIPO Patent Application WO/2016/143559
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: an ink composition for three-dimensional modeling by an inkjet method, which has low viscosity and high ejectability, and which is capable of producing a three-dimensional model having higher tensile strength and higher impact resistance; an ink set which contains this ink composition; and a method for producing a three-dimensional model, which uses this ink composition. This ink composition for three-dimensional modeling contains a photopolymerizable monomer, a polymer and a photopolymerization initiator. The polymer has a weight average molecular weight of from 5,000 to 80,000 (inclusive); the photopolymerizable monomer contains a monomer that is capable of forming a ring structure in the main chain by polymerization; and the difference between the solubility parameter of the photopolymerizable monomer and the solubility parameter of the polymer is from 0.30 (cal/cm3)1/2 to 2.0 (cal/cm3)1/2 (inclusive).
