Water-color ink jet ink

摘要

P To provide water-based inkjet ink which establishes both the suppression of intermittent ejection failure of the ink by Decap and high drying rate and which provides a high-grade image quality and fretting resistance without causing unevenness and etc., ON water-absorbing recording media, of which paper is representative and even ON non water-absorbing recording media. PSOLUTION: The water-based inkjet ink is used in systems printing by heating recording media. The water-based inkjet ink includes at least a pigment and a polymer dispersant, 2-10 mass% of a water-soluble acrylic resin and one or more water-soluble organic solvents selected from glycol ethers or 1,2-alkane diols with a carbon number of 4 or more. The water-soluble acrylic resin has at least a (meth) acrylic acid and a (meth) acrylic acid ester as copolymerization components and has an acid value of 60 mgKOH/g to less than 80 mgKOH/g.
