Title:
インクセット、インクセットを使用して形成された積層体、インクセットを使用して像を形成する像形成方法及び積層体の製造方法
Document Type and Number:
Japanese Patent JP6910939
Kind Code:
B2
Abstract:
Provided is an ink set which exhibits good curability of a first ink applied to a substrate even in cases where the ink set contains the first ink and a second ink and is applied to the substrate. A light-curable ink set which contains a first ink that is applied to a substrate and a second ink that is applied to the first ink, and wherein the first ink and the second ink contain an active energy ray-polymerizable monomer and a photopolymerization initiator. In an absorbance measurement wherein clear inks obtained by removing colorants from the first ink and the second ink are irradiated with light, with respect to the absorbance curves indicating the relationships of the respective absorbances of the clear inks to light having wavelengths from 350 nm to 420 nm, the area of a range where the absorbance of the clear ink of the first ink is higher than the absorbance of the clear ink of the second ink is 0.5 or more.
