い。In the present invention, the method of depositing the titanium oxide or zirconium oxide of the first layer and the zinc oxide of the second layer on the surface of the extender pigment is not particularly limited, and various methods can be used. For example, in order to deposit titanium oxide or zirconium oxide of the first layer, metal alkoxide or acetylacetone metal salt is used as a raw material, and an extender pigment is suspended in an alcohol solution of these,
After heating and refluxing, water is added dropwise to this solution for hydrolysis. Then, after the obtained product is filtered, washed and dried, when the adherend is a hydroxide, firing may be performed. Further, after depositing the first layer, for depositing the zinc oxide of the second layer, for example, zinc acetylacetonate is dissolved in alcohol, and water is dropped into this solution to cause hydrolysis. The obtained product may be filtered, washed, and dried.

It is necessary to be in the range of 02 to 2.0. If it is less than these values, a sufficient effect cannot be obtained, and if it exceeds these values, the transparency is lowered, which is not preferable. Further, it is preferable that the amount of titanium oxide or zirconium oxide deposited on the first layer is 0.2 to 20% by weight and the amount of zinc oxide deposited on the second layer is 10 to 600% by weight with respect to the extender pigment.

The amount of zinc oxide deposited can be determined by suspending the pigment in dilute hydrochloric acid, ultrasonically dispersing and then filtering, and quantifying the amount of zinc in the obtained filtrate. Similarly, titanium oxide or zirconium oxide can be used.

After heating to 0 ° C, add 700 ml of isopropyl alcohol to 1 part of water.
After adding 40 ml and aging for 2 hours, a titanium oxide or zirconium oxide adhered pigment was obtained. The obtained pigment was calcined at 700 ° C. for 1 hour. Further, 2 g of this pigment is dissolved in 400 ml of 0-4.0 g of zinc acetylacetonate.
Was suspended in an ethanol solution of, and heated to 80 ° C. and refluxed, water was added dropwise at a rate of 100 ml / h for 3 hours, and aging was performed for 2 hours to obtain a composite pigment. (Evaluation method) After uniformly kneading the pigment with silicone oil so that the pigment concentration becomes 13.5%, a 10 μm coating film is formed on the glass plate using an applicator, and the ultraviolet light transmission amount determines the ultraviolet light. The transparency was determined from the transmittance by a haze meter.
