Title:
ACTIVE ENERGY RAY-CURABLE COMPOSITION, ACCOMMODATION CONTAINER, TWO-DIMENSIONAL OR THREE-DIMENSIONAL IMAGE FORMING APPARATUS, METHOD FOR FORMING TWO-DIMENSIONAL OR THREE-DIMENSIONAL IMAGE, CURED PRODUCT, MOLDED ARTICLE, AND METHOD FOR MANUFACTURING THREE-DIMENSIONAL MOLDED OBJECT
Document Type and Number:
Japanese Patent JP2020056002
Kind Code:
A
Abstract:
To provide an active energy ray-curable composition excellent in color developing property, adhesiveness to a substrate and discharge stability in a high concentration region.SOLUTION: The active energy ray-curable composition contains substantially no surfactant, but comprises: a polymerizable monomer having a static surface tension of 40 mN/m or more at 25°C by 15 mass% or less with respect to the total amount of the active energy ray-curable composition; an organic pigment as a colorant by 2 mass% or more with respect to the total amount of the active energy ray-curable composition; and a dispersant having an amine value of 5 mgKOH/g or more and 35 mgKOH/g or less, the amine value being larger than the acid value of the dispersant, by 15 mass% or more and 70 mass% or less with respect to the mass of the organic pigment. The active energy ray-curable composition has a water content of 500 ppm by mass or more and 3,000 ppm by mass or less.SELECTED DRAWING: None
