Zusammenfassung:	The invention provides resin for water-based ink as well as a preparation method and an application of the resin. The water-based ink is prepared from the following components in percentage by weight: 0.5-30% of pigment colorant, 0.5-10% of the resin for the water-based ink, 5-20% of wetting agent, 0.5-20% of impregnating agent, 5-15% of dissolution stabilizer and the balance of deionized water. The resin for the water-based ink is a polymer microparticle emulsion which is prepared from free radical polymerization monomers in a semi-continuous emulsion copolymerization manner by taking an alkali-soluble high-molecular polymer as an emulsifier and in the presence of a water-soluble peroxide initiator; the particle size of the polymer microparticle emulsion is 50-180nm, the acid value of the emulsion is 30-100mgKOH/g and the glass-transition temperature Tg of the emulsion is from -50 to 50 DEG C. The change of the viscosity of the resin for the water-based ink along with temperatures is low, and therefore, a nozzle cannot be blocked; the water-based ink is suitable for printing on glossy paper and common painting paper; besides, the printed materials are clear in image, good in glossiness, and excellent storage stability and scratch resistance.
