- Example 5 a coating film was formed in the same manner as in Example 5 except that nickel-coated glass flakes B were used instead of the TiO 2 -coated glass flakes A as the brilliant pigment, and the same evaluation was performed. The results are shown in Table 2.
- a coating film was formed in the same manner as in Example 1 except that glass particles were used in place of the brilliant pigment, and the same evaluation was performed. The results are shown in Table 2. '
- Example 4 a coating film was formed in the same manner as in Example 4 except that glass particles were used in place of the glitter pigment, and the same evaluation was performed. The results are shown in Table 2.
- Example 5 a coating film was formed in the same manner as in Example 5 except that glass particles were used instead of the brilliant pigment, and the same evaluation was performed. The results are shown in Table 2.
- a coating film was formed in the same manner as in Example 1 except that the pearlescent force was used in place of the brilliant pigment, and the same evaluation was performed. The results are shown in Table 2.
- Table 3 summarizes the phosphorescent substance, fluorescent substance type, glitter pigment powder type, coating layer type and thickness, optical characteristics, etc. of each coating layer. Show. [Table 2]
- Example 1 Phosphorescence was emitted from the entire film, and light emission could be clearly recognized. In addition, it is brilliant overall and rich in design.
- Example 2 Phosphorescence (Example 2) or fluorescence (Example 3) was emitted from the entire coating, and Example 3 luminescence was clearly recognized. In addition, it has brilliancy as a whole and is rich in design.
- Example 1 Compared with Example 1, the hue of the luminous substance and that of the brilliant pigment are close to each other, giving a clearer impression.
- Example 4 Phosphorescence was emitted from the entire coating film, and light emission was clearly recognized. In addition, it is brilliant as a whole and is rich in design.
- Example 5 Phosphorescence was emitted from the entire coating film, and light emission could be clearly recognized.
- all Examples 6 have a brilliant property and are rich in design. Compared with Example 1, the phosphorescence is stronger.
- Example 7 has higher recognizability, but the glitter of the coating film is slightly inferior.
- Comparative Example 1 Since the glittering pigment is opaque, it is difficult to recognize the fluorescent light or the fluorescent light. Comparative Example 2 It is difficult and the glitter is insufficient.
- Comparative Example 5 Phosphorescence was emitted from the entire coating film, and light emission could be recognized, but there was no glitter and poor design.
- Comparative Example 7 Phosphorescence was emitted from the entire coating film, and light emission could be recognized. However, there was no glitter and poor design.
- Comparative Example 8 Phosphorescence was emitted from the entire coating film. However, light emission was not recognized as in the example, and although the film had brilliancy, it was strongly clouded and poor in design.
- Example 4 From the comparison between Example 4 and Comparative Example 3, when a phosphorescent substance and a brilliant pigment are mixed, if a brilliant pigment having a light-shielding property is used, the phosphorescence becomes considerably weaker and darker, and the visibility of the luminescent coating film decreases. You can see. On the other hand, it can be seen that the use of a highly transparent brilliant pigment allows the luminescence of the phosphorescent substance to be clearly recognized from its transparency.
- the luminous substance is contained on the layer containing the luminous pigment without mixing the luminous pigment with the highest reflectance and the luminous substance. It can be seen that the addition of the layers enhances the phosphorescence of the phosphorescent substance and makes it possible to clearly recognize the luminescence.
- Example 1 and Comparative Example 5 Example 4 and Comparative Example 6, and Example 5 and Comparative Example 7, the reflectance was high even when glass particles having the same luminescent coating composition and high transparency were used. If it is low, the phosphorescence of the phosphorescent substance can be recognized, but there is no glitter and the design is poor. On the other hand, it can be seen that the use of a brilliant pigment having a high maximum reflectivity makes it possible to clearly recognize the phosphorescence of the phosphorescent substance, to have a brilliant feeling, and to achieve a high design.
- Example 1 From the comparison between Example 1 and Comparative Example 8, the use of Pearl My force, which has the same light-emitting coating composition and high reflectivity, slightly deteriorates the transmittance due to poor surface smoothness and appears cloudy. It can be seen that the phosphorescence of the phosphorescent substance can be recognized and has a brilliant feeling, but the opacity is increased and the design is poor. On the other hand, when a glitter pigment using glass flakes with good surface smoothness is used, it can be seen that the phosphorescent of the phosphorescent substance can be clearly recognized and has a glittering feeling, and a product having a high design property can be obtained.
