This invention relates to a method for manufacturing a direct thermal linerless label web (100), the direct thermal linerless label web (100) comprising a face (110) having a multilayer structure comprising at least three layers, the face comprising a base layer (113), a direct thermal printable coating (115), and an intermediate layer (114) disposed between the base layer and the direct thermal printable coating, wherein the intermediate layer has a grammage in a range between 0.9 g/m2 and 7 g/m2, total amount of mineral pigments in the intermediate layer is equal to or less than 4 g/m2, and a mineral pigment content of the intermediate layer is less than 85 wt. %, preferably equal to or less than 75 wt. %, calculated from total dry weight of the intermediate layer, wherein the method comprises: supplying the face (110), applying a water-based acrylic adhesive coating (121), and the thermally drying the adhesive coating (121) into a pressure sensitive adhesive coating (120), wherein the water-based acrylic adhesive coating (121) is applied onto the face, or the water-based acrylic adhesive coating (121) is applied on to a carrier material, and the method further comprises: transferring the pressure sensitive adhesive coating from the carrier material on to the face. This invention further relates to a direct thermal linerless label web (100), and a use of a direct thermal linerless label (100) in on-demand printing.
