    • 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.
    • 提供记录有信息的层叠材料。 层叠材料包括微球固定层,其中许多透明微球体被布置和掩埋,其中暴露的部分,设置在透明微球的几乎聚焦位置处的反射层,以及至少部分地设置在透明微球的表面上的透明树脂层 微球固定层,其中透明微球体暴露。 透明树脂层使透明微球的聚焦位置移动,以减少设置透明树脂层的部分的后向反射率。 使用设置有透明树脂层的部分与未设置透明树脂层的部分之间的回射率差异来记录信息。
