A laminated material on which information is recorded is provided. The laminated material includes a microsphere fixing layer in which many transparent microspheres are arranged and buried with parts thereof exposed, a reflection layer disposed at almost the focus positions of the transparent microspheres, and a transparent resin layer provided at least partially on a surface of the microsphere fixing layer, where the transparent microspheres are exposed. The transparent resin layer shifts the focus positions of the transparent microspheres to reduce the retroreflectance of the portions where the transparent resin layer is provided. The information is recorded with the use of a difference in retroreflectance between the portions where the transparent resin layer is provided and portions where the transparent resin layer is not provided.

Laminated material having recorded information thereon, article to which the same is affixed, information reading method, and information reading apparatus

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 memberof the present invention comprises a transparent material layeron which an information code is recorded, and a reflection-reduction layerprovided at the opposite side from a side where the information code is observed. The transparent layercomprises low-reflectance portionsand high-reflectance portionshaving a higher reflectance than the low-reflectance portionsThe information code is recorded as a distributed pattern of the high-reflectance portionsThe reflection-reduction layerreduces reflected light advancing to the transparent material layer

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 lnT,/lnT,(T,: 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.
