。In order to improve the surface hardness of products and semi-finished products that tend to get scratched on the surface during transportation and handling, such as molded products made of synthetic resins such as AS resin and polyethylene terephthalate, A method is used in which a coating composition containing an ultraviolet curable synthetic resin is applied to the surface of a product, followed by irradiation with ultraviolet rays to impart a high degree of surface hardness to the object to be coated. Although the method has the advantage that it can be completed by combining a simple process of applying a coating agent, which is a coating composition, and a subsequent ultraviolet ray irradiation process, the surface hardness of the resulting coating film is different from that of the coating composition. Depending on the type of synthetic resin in the product, the surface hardness may only be around 2H, and even if the type of synthetic resin used in the coating composition is selected, the surface hardness will be around 4H at most, and under extreme conditions. The reality is that it is not possible to completely prevent scratches and the like during handling operations.

It is something. Since this hollow powder carbon contained in the ultraviolet curable coating composition of the present invention has an extremely low specific gravity compared to other components in the composition, coatings containing hollow powder carbon When the coating composition is applied to the surface of the object to be coated to form a coating layer, hollow powder carbon is applied to the surface of the coating layer before the coach ink layer is cured by ultraviolet irradiation treatment. As a result, a coating film in which hard hollow powder carbon is deposited is formed on the surface of the cured coating film, and this hollow powder carbon in the coating film plays a role similar to sand in sandpaper. As a result, a coating film with extremely high surface hardness can be obtained.
