- the paint was applied to a slate test piece (30 mm x 30 mm) at a thickness of 150 mm, and the sunlight reflectance according to JISR 3 10 5 was measured. Furthermore, a coating film was formed on a similar slate test piece with a thickness of 200 ⁇ in, and was allowed to stand outdoors, and the change in surface temperature with time was measured.

It could not be used (Comparative Example 5).
- the test paint of Example 1 in which spherical silica was blended from the actual surface temperature measurement in the outdoors has a low surface temperature even when no paint is applied. It was revealed that the surface temperature can be kept lower than that of the test paint of Comparative Example 1 which does not contain silica and Comparative Example 6 which is a commercially available product, and it has been found that it has high heat shielding properties. Therefore, it was found that heat shielding properties can be exhibited by adding silica fine particles to the water-based coating composition.
- both spherical silica and crushed silica have heat shielding properties, and the crushed silica force may exhibit the same level of heat shielding properties as spherical silica, but can be blended in large amounts.
- Spherical scouring force can sufficiently exhibit high heat shielding properties, but crushed silica cannot be blended sufficiently, so that it cannot exhibit the same degree of heat shielding properties as spherical silica. I can guess.
