An adhesive label includes a polymeric first film layer that has an affinity for water. The label is useful in various labeling applications and especially adhesive labeling of reusable and recyclable containers which require removal of the label during a washing process in a warm or hot washing fluid.

A label assembly including one or more dissolvable thermal direct adhesive labels and methods of assembly and use. According to one embodiment, each label includes a base layer, a thermal direct layer, an adhesive layer, and a barrier layer. The base layer, which has an upper surface and a lower surface, is water-dissolvable and may be made of a water-dissolvable paper. The thermal direct layer is positioned directly over the upper surface of the base layer and functions in the conventional manner to produce markings therein in response to heat. The adhesive layer is water-dissolvable and is positioned below the lower surface of the base layer. The barrier layer, which is positioned directly below the lower surface of the base layer and directly over the adhesive layer, serves to prevent migration of the adhesive layer through the base layer and into contact with the thermal direct layer.

A method for recycling materials having an affixed label is disclosed. The present invention also includes labels and adhesives that is readily removable from a material during a process for recycling the material.

Processing and use of ultra-high solids formulations wherein no drying step is needed for the formulation to be incorporated in a wide variety of applications. Adhesives, top-coatings, sealants, fasteners are amongst the use areas.

A method for recycling materials having an affixed label is disclosed. The present invention also includes labels and adhesives that is readily removable from a material during a process for recycling the material.

A linerless wash-off label (100) comprising a paper-based face (101, 201) and pressure sensitive adhesive (102) is provided. The paper-based face (101, 201) comprises a base paper (206) and a release layer (203), and the release layer (203) and the pressure sensitive adhesive (102) are arranged on opposite sides of the base paper (206). The pressure sensitive adhesive (102) comprises a water-based acrylic emulsion polymer composition, the pressure sensitive adhesive (102) is sensitive to washing conditions, and the base paper (206) comprises wet strength resin and has water absorptiveness of from 10 to 30 g/m.sup.2 when measured according to an ISO standard 535 (contact time 60 s). Further, a label product roll comprising the linerless wash-off labels (100) as well as a labelled item comprising an item and a linerless wash-off (100) label are provided. Still further, use of the linerless wash-off label (100) and method of manufacturing a linerless wash-off label web for providing the linerless label product roll are provided.

The invention relates to a method for manufacturing a label (2) comprising a face (1) and a pressure sensitive adhesive layer (4), wherein the method comprises steps of applying an acrylic adhesive onto a first surface of the face (1), wherein the acrylic adhesive comprises a wash-off additive comprising a resinous material and a grafted rosin ester, and drying the acrylic adhesive in order to form an acrylic pressure sensitive adhesive onto the first surface of the face (1), thereby obtaining the label (2). The invention further relates to a label comprising a face (1) and a pressure sensitive adhesive layer (4), wherein the acrylic adhesive comprises a wash-off additive comprising a resinous material and a grafted rosin ester.

The invention relates to a method for manufacturing a wash-off label (2) comprising a face (1) and a pressure sensitive adhesive layer (4), wherein the face (1) comprises a thermoplastic film, and the method comprises applying an acrylic adhesive onto a first surface of the face (1), wherein the acrylic adhesive comprises a wash-off additive, the wash-off additive comprising are sinous material, and a grafted rosin ester which is a rosin ester grafted with a capped polyalkylene glycol, wherein the capped polyalkylene glycol is apolyalky lene glycol end-capped by an alkyl ether, and drying the acrylic adhesive in order to form an acrylic pressure sensitive adhesive onto the first surface of the face (1), thereby obtaining the wash-off label (2). The invention further relates to a wash-off label.

At parties and other social gatherings, drinks are typically served in non-descript glassware. As a result, patrons may be unable to distinguish their glass from others once they are set down on a table. Unintentionally swapping glasses can be unsanitary and wasteful (increasing costs for the host of the event). To solve these problems, the inventors have created an easy way for people to mark their glassware with individualized stickers that are easy to remove at the conclusion of a gathering. These water-soluble stickers can be designed around the theme of the gathering. Guests select from a set of unique stickers and adhere one to their glassesthey work on all glassware (even without stems). At the end of the gathering, the host can easily remove the drink markers by running the glassware under water or by placing them in the dishwasher as they normally would.
