Patent ID: 8314936

Claim:
An optical layered body for use as a display and having an anti-contamination property, wherein said optical layered body comprises a hard coat layer located on a light-transmitting substrate, and wherein the anti-contamination property represented by ΔE*ab specified by International Commission on Illumination (CIE) after the surface is artificially fouled is 3.5 or less, said ΔE*ab is the color difference (ΔE*ab) between the optical layered body which is fouled or may have been fouled and the optical layered body which is not fouled and is determined by calculating chromaticity x, y values and luminance Y values of diffuse reflected light based on CIE, and further converting the chromaticity x, y values and luminance Y values of diffuse reflected light to a*b*L* values.
