摘要:
There is provided a method for forming a brilliant coating film with an excellent brilliant appearance by using aqueous first and second base coating compositions without preheating the applied first base coating composition. In the method, the aqueous first base coating composition is applied to a substrate to form a first base coating, the aqueous second base coating composition is applied to the first base coating to form a second base coating, a clear coating composition is applied to the second base coating to form a clear coating, and then the uncured coatings formed are simultaneously heated and cured, under controlling the solid contents of the first and second base coating compositions and the ratio therebetween, or the brilliant pigment mass concentrations of the base coating compositions and the ratio therebetween, or the mass ratio, the evaporation rate, and the solubility parameter of a solvent contained in the first base coating composition.
摘要:
The invention provides a method of improving the electrical conductivity of a resin article and a method of coating the article, with high productivity and. without using an inorganic conductive substance-containing primer. The technology comprises coating the substrate with a coating composition essentially consisting of a film-forming component, a nitrogen-containing compound of general formula (1), and a solvent and subjecting the coated surface to corona discharge treatment. The resultant film with improved electrical conductivity is then electrostatically coated.R.sup.1 --Y (1)wherein R.sup.1 represents an alkyl or alkenyl group of 5-21 carbon atoms; Y represents ##STR1## R.sup.2 and R.sup.3 may be the same or different and each represents an alkyl group of 1-4 carbon atoms; m represents 2-3; R.sup.4 represents --H or --CH.sub.3 ; A represents ##STR2## where n represents 1-5.
