Document Type and Number:
WIPO Patent Application WO/2012/165107
Kind Code:
A1
Abstract:
Disclosed is a fingerprint stain-resistant substrate characterized by comprising, at positions with which fingers are brought into contact of a smooth surface of a substrate having light transmittance, light reflectivity or gloss, concave holes which each collect a fingerprint component adhering to the smooth surface by capillary force, and characterized in that the sizes of the square roots of the projected areas of the holes in front view are 10-300 μm, the mean depth of the holes is 0.2-50 μm, and the area ratio of the total area of the holes present in an observation region of the smooth surface to the area of the observation region is 10-85%. This substrate has an excellent fingerprint stain resistance.
