<p>PURPOSE:To obtain a block-print ink which has good washability with water and water resistance, by mixing a pigment, an alkali-soluble resin, an alkalizing agent, a high-boiling pt., water-soluble organic solvent, and a polyoxyethylenealkylamine. CONSTITUTION:A polyoxyethylenealkylamine is incorporated into a water-base block-print ink at least consisting of a pigment, an alkali-soluble resin, an alkalizing agent, and a high-boiling pt., water-soluble organic pigment. As the polyoxyethylenealkylamine, which is used to improve the washability with water, polyoxyethylenestearylamine, polyoxyethyleneoleylamine, etc. are preferably used. An example of the alkali-soluble resin, which is used as a fixing agent and vehicle and becomes soluble in water by the use of an alkalizing agent in combination, is a (meth)acrylic resin or a maleic resin.</p> |
