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.

The invention discloses a water-based acrylate pressure-sensitive adhesive emulsion as well as a preparation method and application thereof, and the preparation method comprises the following steps: S1, providing an acrylate pre-emulsion A and an initiator solution B; s2, dropwise adding a part of the acrylate pre-emulsion A into the initiator solution B, and carrying out a heating reaction to obtain a polymer A emulsion; s3, providing a monomer composition B, and mixing the rest of the acrylate pre-emulsion A and the monomer composition B to obtain an acrylate pre-emulsion B; and S4, dropwise adding the acrylate pre-emulsion B into the polymer A emulsion, and heating for reaction to obtain the water-based acrylate pressure-sensitive adhesive emulsion. The water-based acrylate pressure-sensitive adhesive emulsion prepared by the preparation method disclosed by the invention has relatively good adhesiveness, mobility and PVC shrinkage resistance after being coated on a PVC base material.
