In order to improve the adhesion of water-based ink, adopt different kinds and contents of resin, adhesion promoter and base material wetting agent to compound water-based ink. Test the contact Angle of ink on CD, and coating the ink on CD to test the adhesion of ink. The results of the study show that: the kinds of resin has a great influence on the adhesion of water-based ink; right kind of resin and adhesion promoter matching can effectively enhance the adhesion of water-based ink; the wettability and adhesion of ink has a certain relationship, wettability is necessary condition of adhesion of ink, adding appropriate contents of base material wetting agent can improve the adhesion of ink.
