It is an object of the present invention to provide a laminated member with an recorded information code, having a high reading accuracy, which do not detract from product design and which do not require a special reading apparatus. A laminated member 10 of the present invention comprises a transparent material layer 12 on which an information code is recorded, and a reflection-reduction layer 14 provided at the opposite side from a side where the information code is observed. The transparent layer 12 comprises low-reflectance portions 18 and high-reflectance portions 16 having a higher reflectance than the low-reflectance portions 18. The information code is recorded as a distributed pattern of the high-reflectance portions 16. The reflection-reduction layer 14 reduces reflected light advancing to the transparent material layer 12.

A yellowish scaly powder is characterized in that a scaly powder surface is coated with a composite metal oxide of titanium and nickel or a composite metal oxide of titanium, nickel, and a third metal component. The yellowish scaly powder has a favorable yellowish color tone, in which color tone and glossiness can be easily adjusted, and which is excellent in pigment characteristics such as safety, light resistance, acid resistance, base resistance, heat resistance, and dispersion stability,
摘要:
The present inventors conducted investigations in order to develop a metal oxide which enables effective UV-screening; i.e. which has excellent screening ability against ultraviolet rays, particularly against long-wavelength ultraviolet rays, as well as excellent visible-light transmission; and to provide a UV-screening composition that contains the metal oxide and can be applied to external use. As a result, the present inventors have found that zinc oxide produced by a particular method has a characteristic form; i.e., primary particles having an average particle diameter of 50-100 nm aggregate in a planer shape, and a ratio represented by lnT360nm/lnT400nm (Txnm: transmittance of transmitted light of X nm) of 10 or more, and exerts excellent screening effect against long-wavelength ultraviolet rays as well as excellent visible-light transmission. The present invention has been accomplished based on this finding. The zinc oxide of the present invention effectively exerts the above-described excellent characteristics; i.e. UV-screening effect and transparency, and can be applied to a composition for external use such as make-up cosmetics or sunscreen cosmetics.
