In the spray-on-spray type pearl uv coating composition of the present invention, the dispersant is used to exhibit the effect of the pearl luster and alignment after film formation. If the dispersant is not used or if it is added too much, it may cause a phenomenon such as a coating film flow and unevenness of the surface. The pearl coating ultraviolet coating composition for primary coating of the present invention is applied by spraying, so that a solvent is used to reduce the viscosity during spraying. The solvent can be added during the blending of the ingredients, or it can be added at the end of the spray, and the viscosity of the composition is adjusted to suit the spray. However, from the viewpoint of self-operability, the solvent should be appropriately added when the components are blended, and the margin is further added when the viscosity is finally adjusted. The content of the organic solvent is not limited as long as the desired viscosity can be obtained. However, it is usually from 150 to 500 parts by weight, preferably from 200 to 450 parts by weight, more preferably from 220 to 400 parts by weight, based on 100 parts by weight of the total of the components (A) and (B), TP050202 17 1290566. The content of such solvents is the total amount of organic solvent ultimately contained in the composition of the present invention, i.e., the solvent to be added if necessary for blending other components. ♦ Dissolve and disperse the components contained in the composition during the coating process to obtain fluidity, which is suitable for surface coating by spraying. The solvent evaporates after the coating film is dried. Although the solvent is not a component of the coating film, it has a great influence on the film properties (gloss, adhesion, etc.). Specific examples of the organic solvent to be used in the coating composition of the present invention include: alkanes such as n-hexanol, n-heptane, isoheptane; aromatic hydrocarbons such as methyl*benzene, xylene; ketone Such as methyl ethyl hydrazine OIEK), acetone, cyclohexanone, 4-pyridyl-4-methyl-2-pentanone; esters such as isobutyl acetate (IBAC), ethyl acetate (EAC), butyl acetate Ester (BAC), amyl acetate; alcohols such as ethanol, isopropanol, n-butanol, isoamyl alcohol; ether alcohols such as ethylene glycol monobutyl ether (also known as butyl cellosolve, BCS), ethylene glycol Ethyl acetate (also known as cellosolve acetate, CAC), ethylene glycol monoethyl ether (also known as ethyl cellosolve 'ECS), propylene glycol monomethyl mystery, propylene glycol monomethyl ether acetate (PMA), propylene glycol Methyl ether propionate (pmp). The use of a solvent allows the composition of the present invention to level and spread the coating film after spraying. The amount of solvent used will be determined according to the sprayer's habits or the ultimate goal. The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention. [Examples] Example 1 [Preparation of composition] The coating composition of the present invention was formulated in accordance with the components and ratios listed in Table 1 below.
