案されている。For a paint for such a purpose, a chlorinated polypropylene-modified (meth) acrylic resin having good adhesion to a polyolefin resin such as polypropylene is used as a vehicle, and a large amount of colloidal silica is used as a matting agent. It is used as a mixture. Further, in order to obtain a coating film having an extremely low glossiness of 60 degrees or less of 1.5 or less, the surface hardness of the coating film is increased and the average particle diameter of 10 to 10 is used as a matting agent so that the scratch resistance does not decrease. A paint containing hard resin particles such as cross-linked acrylic resin particles of 20 μm has been proposed.

Further, the value of 60-degree glossiness refers to that measured by an ordinary method using a commercially available specular gloss meter.
If the surface hardness is less than 3, the surface hardness will be insufficient and the scratch resistance will be reduced, and if it exceeds 10, the coating film will be stained by the shavings of the nail.

It becomes necessary, the coating becomes brittle, the adhesiveness is lowered, and the chemical resistance is lowered. The thickness of the matte coating film is not particularly limited, but it is usually 15 to 40 μm, and if it is thinner than this, the strength of the coating film itself is lowered and peeling easily occurs, and if it is thicker than this. The cost will increase.
