Abstract

A water-based ink comprises an ink raw material, water, a resin, a desiccant, a defoamer, a hardener, a color fixative, and a dispersant. Based on the total volume of the water-based ink, the ink raw material has an amount of from 10 volume percentage (vol %) to 15 vol %, the water has an amount of from 60 vol % to 67 vol %, the resin has an amount of from 6 vol % to 12 vol %, the desiccant has an amount of from 5 vol % to 10 vol %, the defoamer has an amount of from 3 vol % to 8 vol %, the hardener has an amount of from 4 vol % to 9 vol %, the color fixative has an amount of from 2 vol % to 7 vol %, and the dispersant has an amount of from 3 vol % to 9 vol %. The printing film produced by the water-based ink is suitable for plastic flooring.
