4. The emulsion adopts a core-shell structure, the traditional base paint can damage a protective layer of the protective adhesive to cause color bleeding under the action of high shear, the reaction strength of the emulsion to the protective adhesive is enhanced through the increase of the hydrophilicity of the outer layer, and the base paint achieves good effects of color bleeding resistance and color spreading under the synergistic effect of ethyl cellulose.
