    Abstract: An adhesive label is described comprising a backing material, a pressure-sensitive adhesive layer attached to the backing material and either a release liner attached to the adhesive layer or a release coating on the other side of the backing material. The backing material is made of paper or home compostable and biodegradable polymer film, and the pressure-sensitive adhesive layer is made from an aqueous polyurethane dispersion pressure-sensitive adhesive. At least 60% by weight of the polyurethane is composed of diisocyanates, polyesterdiols, and at least one bifunctional carboxylic acid selected from di hydroxy carboxylic acids and diamino carboxylic acids, wherein the polyurethane has no melting point above 20° C. or wherein the polyurethane has a melting point above 20° C. with an enthalpy of fusion lower than 10 J/g, and wherein a film of the polyurethane adhesive preferably decomposes at home compost conditions to more than 90% by weight into CO2 and water within 360 days.
