Abstract
Official abstract text for this publication.
A radiation-curable ink jet ink set includes a radiation-curable dark-colored ink having a surface tension γ1 and a radiation-curable light-colored ink having a surface tension γ2. The surface tensions of the radiation-curable inks satisfy γ1>γ2.
First claim
Opening claim text (preview).
What is claimed is: 1. A radiation-curable ink jet ink set, comprising: a radiation-curable dark-colored ink having a surface tension γ1; and a radiation-curable light-colored ink having a surface tension γ2, wherein the surface tensions of the radiation-curable inks satisfy γ1>γ2, and each of the dark-colored ink and the light-colored ink includes a polymerizable compound. 2. The radiation-curable ink jet ink set according to claim 1 , wherein the surface tensions of the radiation-curable inks satisfy γ1−γ2≥5.0 mN/m. 3. The radiation-curable ink jet ink set according to claim 1 , wherein at least one of the dark-colored ink and the light-colored ink contains: a compound represented by the following general formula (I): wherein R 1 represents a hydrogen atom or a methyl group, R 2 represents a divalent organic residue having a carbon number of 2 to 20, and R 3 represents a hydrogen atom or a monovalent organic residue having a carbon number of 1 to 11; and an acylphosphine oxide-based compound.
