US 2004/0105976 A1 · Colored adhesive tape

Abstract

A coloured tape arranged for attachment as individual tabs to a paper stock file folder is formed by providing a base film and applying to the base film a first layer comprising a laminating adhesive containing the colouring agent from which the solvents are driven off. When dried, a hot melt adhesive is applied to the laminating agent and chilled. The tape is wound into a roll. At an end use location the tape is cut into tabs and the tabs applied to the paper stock using the hot melt adhesive by heat or by pressure sensitive action to cause the bond to the paper. The application of the colouring agent to the laminating adhesive allows ready admixture of the liquid colouring agent or dry pigments using the solvents in the laminating adhesive. As the colouring agent is immediately adjacent the base film, it is readily visible through the base film as a bold colour.
