Title: Water contact colour change label
Inventor: LU EDISON
IPC: G09F3/02
Filed: 2007-02-21
Abstract: An identification label changes colour in an irreversible manner once put into contact with water / humidity. The label has a water-absorbable paper-based substrate 20 having a surface on which an ink zone 10 formed by printing of water repellent or hydrophobic ink thereon and an opposite second surface on which a coating layer 30 is formed. The ink zone 10 has a colour substantially identical to colour of the substrate 20. The coating layer 30 contains a water soluble substance, which dissolves into water to form a solution that, once being absorbed by the substrate, changes the colour of the substrate 20, the colour of the solution being different from that of the substrate 20. A layer of adhesive 40 is formed below the coating layer 30. Alternatively, the coating layer 30 is formed on a surface of a double-sided adhesive layer and is bonded to a surface of the substrate opposite to the surface on which the ink zone is formed (fig.4). Also disclosed are two corresponding methods of manufacturing the label.
