<p>PURPOSE:To improve the drying resistance of a water-base ink by incorporating therein a polyoxyalkylene diglyceryl ether as a constituent. CONSTITUTION:This water-base ink contains at least a coloring material, water, and a polyoxyalkylene diglyceryl ether. As the coloring material, hitherto known dyes and pigments can be used singly or as a mixture thereof, preferably in an amount of 1-20wt.% based on the total ink. Water, as the principal component, is preferably used in an amount of 30-80wt.% based on the total ink. Examples of the polyoxyalkylene diglyceryl ether include polyoxyethylene diglyceryl ether and polyoxypropylene diglyceryl ether, which are used preferably in an amount of 3-40wt.% based on the total ink.</p> |
