The invention provides a water-based color card. The card comprises a base layer and a water-based surface layer coating the base layer, and the base layer is a plastic layer. The base layer is the environment-friendly plastic layer such as a PP plastic layer, a PET plastic layer, a PE plastic layer or a PVC plastic layer. The water-based surface layer is a material layer with water as a solvent or as a dispersion medium. According to the water-based color card, the water-based surface layer replaces an oily surface layer of a traditional color card, the requirements for environmental protection and safety can be met, the important protection function is achieved for enterprises, surrounding environments and safe production during production, and the requirement for zero discharge is met.Compared with a paper color card, the color card with the plastic base layer has the advantages of high waterproofness, wide application range and long service life.
