<p>PURPOSE:To provide the titled composition having excellent surface hardness and suitable for the protective coating of plastic parts of e.g. various electrical appliances, household articles, etc., by adding natural glass powder composed mainly of SiO2 and Al2O3 and having a specific particle diameter to a paint composition. CONSTITUTION:The objective composition is obtained e.g. by mixing (A) 1- 100pts.wt. of natural glass powder having an average particle diameter of 1- 50mu and composed mainly of (i) 70wt% SiO2 and (ii) 15% Al2O3 in (B) 100pts.wt. of a paint composition (e.g. photo-setting ink). EFFECT:A coating film having excellent optical properties can be applied to a plastic part having transparent surface. USE:Protective coating of plastic parts of automobiles, displays of various game machines, etc.</p> |
