<P>PROBLEM TO BE SOLVED: To readily recognize a trace of a label which has been peeled off, when the label with a peeling detection function which comprises an adhesive layer formed on one surface of a base material and an ink printing layer formed on the other surface opposite to the adhesive layer. <P>SOLUTION: In the printing layer, the infrared absorbing dye which is soluble with a solvent capable of dissolving the adhesive layer is dispersed to be formed an infrared absorption ink pattern which is a higher-order structure of the infrared absorbing dye in an adjoining arrangement. The label with peeling detection function in which the higher-order structure is decomposed to change an infrared absorption spectrum of the infrared absorbing dye in the case of dissolving the infrared absorbing dye with the solvent is provided. <P>COPYRIGHT: (C)2012,JPO&INPIT |
