ARTIFICIAL FINGERPRINT LIQUID, AND FINGERPRINT RESISTANCE EVALUATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide an artificial fingerprint liquid that makes it possible to prepare fingerprint marks comparable to human fingerprint marks and is suitable as a fingerprint resistance evaluation reagent.;SOLUTION: An artificial fingerprint liquid has an oil content, water, and a surfactant of 5 mass%-46 mass% relative to the oil content. The artificial fingerprint liquid is a water-in-oil emulsion.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2016,JPO&INPIT
