Description
２．光輝材
２−１．母材
母材の材料は、特に限定されないが、第１群の発明と第２群の発明とで次のように異なる。
第１群の発明における母材を形成する透明な金属化合物としては、その屈折率が被覆材より小さい場合、それを満たしやすいものとして酸化ケイ素（ＳｉＯ2）、酸化アルミニウム（Ａｌ2Ｏ3）等の金属酸化物を例示でき、その屈折率が被覆材より大きい場合、それを満たしやすいものとして酸化チタン（ＴｉＯ2）、酸化鉄（Ｆｅ2Ｏ3）、酸化セリウム（ＣｅＯ）、酸化ジルコニウム（ＺｒＯ）等の金属酸化物や、硫化亜鉛（ＺｎＳ）等を例示できる。
第２群の発明における母材を形成する透明な金属化合物は、屈折率が塗膜主材の屈折率より０．９以上大きい必要があり、それを満たせば特に限定されないのであるが、それを満たしやすいものとしてＴｉＯ2、Ｆｅ2Ｏ3、ＣｅＯ、ＺｒＯ等の金属酸化物や、ＺｎＳ等を例示的できる。これらの各材料の屈折率を次の表１に示す。
2. Bright material 2-1. Base Material The base material is not particularly limited, but is different between the first group of inventions and the second group of inventions as follows.
As the transparent metal compound forming the base material in the first group of the invention, silicon oxide (SiO 2 ), aluminum oxide (Al 2 O 3 ) and the like are easily filled when the refractive index is smaller than that of the coating material. When the refractive index is larger than that of the coating material, titanium oxide (TiO 2 ), iron oxide (Fe 2 O 3 ), cerium oxide (CeO), zirconium oxide (ZrO) ), Zinc sulfide (ZnS), and the like.
The transparent metal compound forming the base material in the second group of the invention needs to have a refractive index of 0.9 or more larger than the refractive index of the coating film main material, and if it is satisfied, it is not particularly limited. Examples of the metal oxide that can be easily filled include metal oxides such as TiO 2 , Fe 2 O 3 , CeO, and ZrO, and ZnS. The refractive index of each of these materials is shown in Table 1 below.
