PROBLEM TO BE SOLVED: To provide a pseudo skin, which has high transparency, is close to the human skin in the surface shape and outer color, and has natural appearance.SOLUTION: In the pseudo skin, the hue angle by L*a*b* color system is 45-95° and the transparency in the wavelength 650 nm measured by the following method is 0.2-0.6. (Measuring method of transparency). Using a spectral colorimeter, the direction of incident/receiving light is set at (diffused light d/8°) to measure reflectance in the 650 nm of the sample under the following conditions. reflectance (large): the irradiation region is a circle of 11 mm diameter and the measuring region is a concentric circle therein of 8 mm diameter. reflectance (small): the irradiation region is a circle of 4 mm diameter and the measuring region is a circle of the same diameter 4 mm. The transparency is determined from the following formula: transparency=1-reflectance (small)/reflectance (large).COPYRIGHT: (C)2013,JPO&INPIT【課題】透明性が高く、表面形状や外観色が人間の皮膚に近く、見え方が自然な擬似皮膚を提供すること。【解決手段】L*a*b*表色系による色相角が45~95°であり、以下の方法により測定された波長650nmにおける透明性が0.2~0.6である擬似皮膚。(透明性の測定方法)分光測色計を用いて、入射/受光の向き(拡散光d/8°)に設定し、以下の条件でサンプルの650nmにおける反射率を測定する。反射率(大):照射領域を直径11mmの円とし、測定領域をその内側の直径8mmの同心円とする。反射率(小):照射領域を直径4mmの円とし、測定領域を同じ直径4mmの円とする。透明性は、以下の計算式から算出する。【数1】【選択図】なし
