Flat powder 1-7 with diffusion transparently layers of comparative tests the present invention, PET-MMA laminated glitter used in comparative products 2-3 and Example 7 (comparative product 5) respectively separately 0.2g collected, 1 ml of octamethylcyclotetrasiloxane was added thereto to prepare a dispersion liquid which was ultrasonically dispersed, and the dispersion liquid was drawn on a slide glass using a 0.5 mil doctor blade to form a thin film. Five thin films of the same product were produced, but only five extra films of Comparative Product 3 were produced. These thin films were air dried to volatilize octamethylcyclotetrasiloxane. The five extra sheets of the comparative product 3 were air-dried, and then the comparative product 1 was pulled with a 0.5 mil doctor blade so as to overlap the previously applied thin film. The IPA was stripped. The obtained thin film was used as comparative product 4. The flat powder 1-6 and transmittance of 560nm respect thin film of Comparative product 2-4 with diffusion transparently layer of the present invention was measured by a spectrophotometer. The transmittance measured with the integrating sphere attached to the spectrophotometer was TT, and the transmittance measured without the integrating sphere was DT. In addition, as the value of each transmittance, an average value of three thin films obtained by cutting the top and bottom of five thin films of the same product was used. The unit is%. Table 1 shows the results. Light transmitted through the film (total transmitted light, TT) is divided into light traveling straight (straight transmitted light, DT) and light diffusing (diffused transmitted light, ST). Glass with high transparency has a TT of 100%, and all of them are DT, so DT is also 100%. Therefore, a high TT and a low DT indicate that light is diffusely transmitted. The flat powder 2 having a flat powder 1 and the diffusion transparently layer having a diffusion transparently layers of the present invention and the comparative product 3 there is a large difference in DT while showing similar TT. This whereas the comparative product 3 is coated only silica talc, organic polymer and fine particulates in the flat powder 2 having a flat powder 1 and the diffusion transparently layer having a diffusion transparently layer This is because the composite with is coated. Comparative product 4 is obtained by coating organic polymer on comparative product 3, but there is a clear difference in DT between comparative product 4 and comparative product 3, that is, a fine granular material is coated. It is shown that diffuse transmission cannot be obtained only by doing. Flat powder 3-6 with diffusion transparently layer is titanium oxide or iron oxide coating of a high refractive index powder mica or synthetic mica, it just is TT is low, these and comparative product 2 Shows that there is a large difference in DT, that is, it is not possible to lower DT only by coating titanium mica alone or an organic polymer on titanium mica.

<Example 9>
On a flesh color model colored paper having a spectral reflectance close to flesh color, a test pattern was prepared by drawing two black lines with a 0.5 mmφ black point and a 0.1 mm interval, and on this test pattern,
Prepared in Example 8, the flat powder 1 every 6 and comparative 2-4 of thin films, respectively separately, distance and two lines black spots can not be confirmed when alienated test pattern from the thin film having a diffusion transparently layer interval of was determined the distance of the test pattern and the flakes can not be identified. The former is called the point discrimination limit, and the latter is called the interval discrimination limit, and the unit is cm. The spot identification limits and intervals identification limit, each separately measured three times for one thin film an average value, and results further measure three average values cuts both five thin film for the same product did. Table 2 shows the measurement results. The comparison of the point discrimination limits is a comparison of the ability of the film to cover the underlying one (covering power), and the comparison of the line spacing discrimination limits is a comparison of the resolution (soft focusability) of the film. Flat powder 1 having a diffusion transparently layer, flat powder 2 having a diffusion transparently layers, comparative product 2, the comparative product 3 and comparative product 4 is extremely large spot identification limit. Among them, flat powder 1 having a diffusion transparently layer, flat powder 2 having a diffusion transparently layer obscures things because Comparative Product 3 and Comparative Product 4 is used such transparency powder of talc The ability is extremely low, and Comparative Product 2 is a titanium mica but coated with only an organic polymer, and thus also has a low ability to cover the thing . However, the flat powder 1 having a diffusion transparently layers, there is a huge gap in the interval identification limit the comparative product 3 with flat powder 2 and comparative product 4 having a diffusion transparently layers. This whereas those which are comparative product 3 was coated only silica talc, flat powder 1 and the diffusion transparently layers flat to powder 2 Organic polymer and fine particulate having a having a diffusion transparently layer This is because the composite with the product is coated, and the comparative product 4 is obtained by covering the comparative product 3 with the organic polymer. That is, when coated with and the fine particulates organic polymer indicates that hardly identification of the shape of what lies beneath the membrane. Although the flat powder 3-6 with diffusion transparently layer of titanium oxide and iron oxide with a high refractive index powder mica or synthetic mica is coated, it alone is spot identification limit or intervals identified as Comparative Product 2 The limit cannot be lowered, that is, titanium mica coated with an organic polymer and fine particles can lower the point identification limit and the interval identification limit.

<Example 10>
Using flat powders 1-7 and the thin film of the comparative product 2-5 with diffusion transparently layer prepared in Example 8 was measured diffuse reflected by the goniophotometer. The measurement was performed such that light was incident on the film surface at an angle of 45 ° and was received at angles of 30, 45 and 60 °. The measured value was obtained by dividing the reflectivity at 30 and 60 ° by the reflectivity at 45 °, but since both tendencies were substantially similar, a different angle reflectivity ratio of 30 ° / 45 ° was used. The measurement wavelength was 560 nm, and the measurement results were indicated by the average value of three sheets excluding the highest value and the lowest value. Table 3 shows the results. In general, a glossy surface has strong specular reflection. Therefore, the ratio of the non-specular reflectance divided by the specular reflectivity is larger, the diffuse reflectivity is higher, and the smaller ratio is the specular reflectivity. Comparative product 5 is the original glitter, and Comparative product 2 is also close to the original titanium mica and shows strong regular reflection. Comparative product 4 has a strong specular reflectivity, probably because there was too much PMMA on the top layer. Comparative product 3 is obtained by coating talc with only silica, but it can be seen that coating of only fine particles is effective in preventing regular reflection. The comparative product 5 with a flat powder 7 having a diffusion transparently layers are the same glitter, difference being or not or composite of organic polymer and fine granules are coated. That is, when the composite of the organic polymer and the fine granular material is coated, the same effect is obtained as in the case of coating only the fine granular material in the sense of suppressing the regular reflection. Its it has been shown also that high values of flattened powder 1 6 having a diffusion transparently layers.
