Kind Code:

A1

Abstract:

The purpose of the present invention is to provide an ink set capable of sufficiently increasing the strength of a shaped object which is a photo-cured product of color ink and clear ink, and preventing color change in the shaped object. The present invention pertains to a model material ink set used in an inkjet-type optical fabrication method, the model material ink set including color ink and clear ink as model material inks, wherein the color ink and the clear ink each contain an ethylenically unsaturated monomer, the color ink containing, as the ethylenically unsaturated monomer, 30-75 mass% of (meth)acrylate and 10-50 mass% of an ethylenically unsaturated monomer which contains nitrogen atoms and is not (meth)acrylate on the basis of the total amount of the color ink, the clear ink containing, as the ethylenically unsaturated monomer, 30-80 mass% of (meth)acrylate on the basis of the total amount of the clear ink, and the content in the clear ink of the ethylenically unsaturated monomer which contains nitrogen atoms and is not (meth)acrylate being less than 10 mass% on the basis of the total amount of the clear ink.
