As an example, the PVA concentration of the PVA aqueous solution may be used in an amount of 5 to 50 wt%.

An example of forming a mold release layer by applying a mold release agent to a specific mold is to wash the mold with alcohol to completely remove the foreign matter, and then to apply a PVA solution 2 to 4 times at 40 to 50 ℃, a release agent (for example, solvents of Henkel, USA) Wax type release agent product name: 'precoat' may be preferably applied) 3 to 7 times and put in a heat chamber and dried at a temperature of 55 to 90 ℃ for 30 minutes to 7 hours to form a mold release layer on the mold. Can be formed.

In another aspect, the present invention includes the step of forming a transparent coating layer on the release agent layer, the transparent coating layer to ensure the waterproofing and chemical resistance of the bath or washbasin and at the same time beautiful appearance, the bath or washbasin color layer (painting) Layer) serves to protect the color layer and preferably, in order to perform such a function, the thickness thereof is 0.1 to 15 mm. As a specific example, the transparent coating layer may be mixed with acrylic resin and silicone resin in an amount of 100: 1 to 10 parts by weight, and then applied to the release layer 1 to 4 times (including normal coating or spray coating) and then placed in a heat chamber at 70 to 120 ° C. It may be dried at a temperature, preferably may be formed by drying for 1 minute to 1 hour. The acrylic resin and the silicone resin may be commercially available resins. For example, the acrylic resin may be PU500PTA (manufactured by 'Mero Chemical') and KP324 (manufactured by Shin-Yesu, Japan) as the silicone resin.
