An adhesive film that can be wound and stamped having an epoxy-based adhesive compound that can be activated thermally or by UV radiation, and a dye and/or pigment mixed into the adhesive compound for producing a first color change after the activation of the adhesive compound and a second color change after the curing of the adhesive compound.

An aqueous organic pigment dispersion contains a green copper phthalocyanine pigment and an azo-coupled -ketoamide pigment. It also includes an organic pigment dispersant at 40 weight % to 100 weight %, based on the sum of the weights of the organic pigments. The weight ratio of the green copper phthalocyanine pigment to the azo-coupled -ketoamide pigment is from 1:1 to 10:1. The median particle diameter of each of the green copper phthalocyanine pigment and the azo-coupled -ketoamide pigment is less than 85 nm. At least 95% of the total particles of each of the green copper phthalocyanine pigment and the azo-coupled -ketoamide pigment have a particle diameter of less than 150 nm. This dispersion can be used to prepare aqueous green inkjet ink compositions that can be used in various inkjet printing methods.
