Abstract

The specification relates to a wash-off label (100, 200) comprising a face (101, 301) and a pressure sensitive adhesive (102, 302) adjoined to the face, wherein the face (101, 301) comprises corona discharged filmic material and the pressure sensitive adhesive (102, 302) has a composition including at least one acrylic polymer comprising acrylic monomer(s) and/or non-acrylic comonomer(s) having a carbonyl group capable of undergoing a crosslinking reaction, amount of the acrylic monomer(s) and/or non-acrylic comonomer(s) having a carbonyl group capable of undergoing a crosslinking reaction being from 0.1 to 5 wt. % of monomer composition, and a crosslinking agent with dihydrazide functionality, amount of the crosslinking agent being from 20 to 150% with respect to the amount of the carbonyl groups capable of undergoing a crosslinking reaction. The wash-off label (100, 200) is detachable from a surface when exposed to an alkaline washing solution at a temperature of 85 degrees C. the detachability being such that the pressure sensitive adhesive (102, 302) remains attached to the face (101, 301). Further, the specification relates to a labelled item and use of the wash-off label for labelling an item. Still further, the specification relates to a label laminate web and a method of manufacturing the wash-off label as well as to a pressure sensitive adhesive composition for a wash-off label.
