Abstract
The specification relates to an adhesive label comprising a water-borne multilayer pressure sensitive adhesive with enhanced performance. The adhesive label comprises a face layer and a multilayer adhesive adjoined to the face layer. The multilayer adhesive comprises at least two layers of pressure sensitive adhesive. At least one of the at least two layers comprises a pressure sensitive adhesive composition including at least one acrylic polymer which has a reactive group capable of undergoing a crosslinking reaction, and a crosslinking agent. The specification also relates to a labelled item, a label laminate web and a method for manufacturing an adhesive label.
Claims12
An adhesive label comprising:
- a face layer;
- and
- a multilayer adhesive adjoined to the face layer, the multilayer adhesive comprising at least two layers of pressure sensitive adhesive, the multilayer adhesive having a tack on cardboard in a range of from 1 to 7 N/25 mm and/or on glass in a range of from 5 to 13 N/25 mm, when measured according to FTM 9, wherein
- at least one of the at least two layers comprises a pressure sensitive adhesive composition including
- at least one acrylic polymer which has a reactive group capable of undergoing a crosslinking reaction, and
- a crosslinking agent, and
- wherein the reactive group capable of undergoing a crosslinking reaction is a ketone and the crosslinking agent is a crosslinker with dihydrazide or diamino acid functionality,
- wherein the interfaces of the at least two layers of the multilayer adhesive are indistinguishable.
A label laminate web comprising:
- a face;
- a multilayer adhesive;
- and
- a release liner,
- the face being adjoined to the release liner via the multilayer adhesive, wherein the multilayer adhesive comprises at least two layers of pressure sensitive adhesive, the multilayer adhesive having a tack on cardboard in a range of from 1 to 7 N/25 mm and/or on glass in a range of from 5 to 13 N/25 mm, when measured according to FTM 9, and
- at least one of the at least two layers comprises a pressure sensitive adhesive composition including
- at least one acrylic polymer which has a reactive group capable of undergoing a crosslinking reaction, and
- a crosslinking agent, and
- wherein the reactive group capable of undergoing a crosslinking reaction is a ketone and the crosslinking agent is a crosslinker with dihydrazide or diamino acid functionality,
- wherein the interfaces of the at least two layers of the multilayer adhesive are indistinguishable.
