The present application relates to a linerless self-adhesive label, method for labelling an item, and to a labelled item.

The invention relates to a surfactant comprising a grafted rosin ester which is a rosin ester grafted with a capped polyalkylene glycol, wherein the capped polyalkylene glycol is a polyalkylene glycol capped by an alkyl ether and an aqueous dispersion consisting of an aqueous phase and resin particles dispersed in the aqueous phase, wherein the dispersion comprises the surfactant according to the invention.

Provided herein is a solvent-based pressure sensitive adhesive comprising a polymer comprising a vinyl acetate monomer, an acrylic ester monomer, and a monomer having hydroxyl or amine functionality. The adhesive also comprise a crosslinker. The coated and dried adhesive has outgassing of less than 2000 ng/cm.sup.2, even when applied to an electronic device that is operated at elevated temperature.

A debonding tape includes a first tape layer including a first base layer having a first modulus and a first adhesive layer on the first base layer, wherein the first tape layer has a first diameter. The debonding tape includes a second tape layer on the first tape layer and supporting the first tape layer, wherein the second tape layer includes a second base layer on the first adhesive layer and having a second modulus greater than the first modulus, an intermediate layer on the second base layer, and a second adhesive layer on the intermediate layer. The second tape layer has a second diameter smaller than the first diameter such that a circumferential portion of the first tape layer is exposed in a cross-sectional view.

Provided is a laminate and a hot melt-type adhesive label that suppress curling due to swelling while having a pulp-paper feel. The laminate includes a porous substrate layer and an adhesive resin receiving layer on one side of the porous substrate layer, and the adhesive resin receiving layer contains an amorphous resin.

The object of the present invention is to provide an alkali-dispersible hot melt pressure-sensitive adhesive which (i) has a high alkali-dispersibility, (ii) is excellent in strength to retain the label, (iii) hardly causes an adhesive residue problem and (iv) is capable of reducing stringing. The present invention relates to an alkali-dispersible hot melt pressure-sensitive adhesive comprising: (A) a thermoplastic block copolymer which is a copolymer of a vinyl-based aromatic hydrocarbon and a conjugated diene compound, (B) a tackifier resin and (C) at least one selected from the group consisting of a fatty acid and a derivative thereof, wherein the thermoplastic block copolymer (A) comprises (A1) a styrene-based block copolymer having a styrene content of less than 40 mass % and the tackifier resin (B) comprises an α-methylstyrene-based resin.

A label including a base material with at least one adhesive region and a cover material, a label tape and a method for manufacturing labels are disclosed. The method includes providing a base material web and applying at least one adhesive to the base material web along at least one row by means of at least one applicator. The adhesive is applied to the base material web intermittently along the row so that the row comprises a plurality of individual adhesive regions spaced apart from one another by adhesive-free regions. The method also includes applying a cover material to at least some regions of the base material web so that a plurality of the applied adhesive regions are completely covered by the cover material, and at least partially separating the base material web and/or the cover material exclusively along adhesive-free regions by means of at least one separating device.

An acrylic emulsion pressure-sensitive adhesive composition is provided. More particularly, an acrylic emulsion pressure-sensitive adhesive composition that may become easily removable when being impregnated with water in a water-borne removal process while being able to realize excellent tacky/adhesive strength for a substrate to be adhered is provided.

In accordance with the present application, there is provided a release liner and method of preparing a liner for a label assembly. The release liner includes paper having a first side that does not have a machine finish or gloss finish or a coating; and a silicone treatment applied to the first side of the paper. The method of preparing a liner for a label assembly includes applying a coat of silicone to a paper at a side of the paper that does not have a machine finish or gloss finish and is otherwise uncoated; and curing the silicone. The release liner includes paper having a silicone coat weight of 0.5 lb/ream or less.

A method of applying a linerless label to an article wherein a web of joined labels is die cut from a web of label material in which the adhesive is protected by a water-soluble coating which provides a cushion between an anvil and die cutting means. The water-soluble coating is at least partially removed by exposure to water in a press following die-cutting, in a label applicator, or in an off-line unit. The web of joined labels may be wound and unwound between each of the above options. The web of joined labels may be separated in a label applicator by breaking a weakened boundary between adjoining labels or by cutting at a boundary between the label and the adjoining label. The linerless label may contain anti-counterfeit means that may be subsequently identified overtly and/or covertly.
