Title:
INK COMPOSITION FOR AQUEOUS INK JET
Document Type and Number:
WIPO Patent Application WO/2015/111645
Kind Code:
A1
Abstract:
Provided is an ink composition for an aqueous ink jet having superior storage stability, dot extendability and uniformity, even when printing on non-absorbent media. The ink composition for an aqueous ink jet contains a pigment, an alkali-soluble resin, a basic compound, a water-soluble organic solvent, a surfactant (A) and a surfactant (B), and is characterized in that: the surfactant (A) is an acetylenic diol surfactant with a hydrophile-lipophile balance (HLB) of 4 to 9, and the content of the surfactant (A) in the ink composition for an aqueous ink jet is 0.1 to 10 mass%; and the surfactant (B) is is an acetylenic diol surfactant with an HLB of 13 to 16, and the content of the surfactant (B) in the ink composition for an aqueous ink jet is 0.1 to 10 mass%.
