<P>PROBLEM TO BE SOLVED: To provide an oil detection sheet whose detection object is limited to oil, which is simple and at low cost, avoids an influence of dew condensation and water to detect only the oil, in the that securement of detection performance is easy on manufacture. <P>SOLUTION: The oil detection sheet has a colored color identification film on the rear surface of an optical irregular reflection transparent film, and the optical irregular reflection film sheds water by including water-shedding quality and lipophilic nature in addition to having optical irregular reflection nature by rugged structure, and a color of the color identification film of the ground is recognizable by the fact that only the oil is absorbed by the rugged structure, becomes wet and spreads. <P>COPYRIGHT: (C)2012,JPO&INPIT |
