Background
The plastic paint in the current market has a plurality of varieties, but mainly plays roles of decoration and protection, and has the main characteristics of diversified color varieties, bright color, good adhesive force on plastic substrates, high durability and relatively single function.
In recent years, blind box toys are popular. The blind box is that the product is not specifically marked on the outer package of the product, and the content of the product can be obtained after the blind box is opened. Most of playing methods in the existing blind box toy market are realized through packaging, namely, the style of the toy inside can be really known only after the packaging is folded. If a dissolvable coating could be provided that would completely cover the finished toy or partially cover the finished toy, would provide a significant improvement in the playability of the product of the blind box toy. However, it is difficult to achieve the above effects on plastic substrates with conventional coatings.

In the aspect of the mixed solvent, the effect paint is mainly applied to a plastic toy substrate, and the surface of the plastic toy may be coated with traditional paint.
Further, based on the mass of the diluent being 100%, the diluent is as follows: ethanol 0-100%, distilled water 0-100%, and can be adjusted according to construction requirements.
Further, the preparation method of the varnish comprises the following steps: distilled water is added into the mixed solvent, then hydrophilic nonionic monomer modified aqueous acrylic resin is slowly added for dispersion and dissolution, polyether polyol and polyethylene glycol are added while stirring, and after the polyether polyol and the polyethylene glycol are completely dissolved, a functional auxiliary agent is added;
the preparation method of the colored paint comprises the step of adding at least one of water-based color paste, water-based silver powder, pearl powder, fluorescent powder and matte powder into the varnish;
