This invention relates to a method for manufacturing a direct thermal linerless label web (), the direct thermal linerless label web () comprising a face () having a first side () and a second side (), the face comprising a direct thermal printable coating, wherein the method comprises supplying the face (), and applying modified adhesive coating () on to a substrate (). The modified adhesive coating comprises water-based acrylic adhesive, and emulsified silicone additive. The method further comprises thermally drying the modified adhesive coating () on the substrate () into a pressure sensitive adhesive coating (). The substrate is the face () or a carrier material (). This invention further relates to a direct thermal linerless label web (), and a use of a direct thermal linerless label () in on-demand printing. 3. The method according to claim 1 , the method further comprising:{'b': ['150', '150', '121', '120'], 'i': 'a', '#text': 'providing alternating adhesion areas and adhesion-free areas (, ) before the modified adhesive coating () is dried into the pressure sensitive adhesive coating ().'}4. The method according to claim 3 , wherein the method comprises:{'b': ['121', '110', '611', '150', '110', '611'], '#text': 'removing at least 10% of the modified adhesive coating () from the substrate (, ) prior to drying to provide alternating adhesion areas and adhesion-free areas (), preferably by using a wiping blade, wherein the blade is arranged at a wiping angle of 75-85 degrees with respect to the surface of the substrate (, ), or'}{'b': ['121', '150', '150'], 'i': 'a', '#text': 'applying the modified adhesive coating () locally onto the substrate to provide the alternating adhesion areas and adhesion-free areas (, ).'}5110. The method according to claim 4 , wherein said substrate is preferably the face () claim 4 , and the method comprises{'b': ['150', '150', '121'], 'i': 'a', '#text': 'providing moisture to the adhesion-free areas (, ) prior to drying of the ...
