The invention relates to a novel, reactive 2-component adhesive system, preferably in film form, for adhering diverse materials, such as for example, metal, wood, glass and/or plastic.

A shop towel device adheres to and covers the exterior of a garment to allow for wiping of the hands without soiling the garment. The device includes a base layer, the base layer being impermeable by fluids. An outer layer is coupled to and coextensive with the base layer. The outer layer is constructed of a fluid absorbent material. An inner layer is coupled to the base layer such that the base layer is between the outer layer and the inner layer. The inner layer is adherent for adhering to a garment such that the outer layer is exposed on the garment.

A substrate-free adhesive tape that is excellent in adhesive physical properties and is suitable for a continuous process is provided. The substrate-free adhesive tape includes a release film, and an adhesive layer provided on one surface of the release film and the adhesive layer containing a cured product of an adhesive composition, wherein when the release film is fixed on the outer surface of a semicircular tip part of a jig, the semicircular tip part having a radius of 22.5 mm, a breaking distance of the adhesive layer is 110 mm or less when the adhesive layer is stretched at a rate of 20 m/min from a semicircular center of the semicircular tip part toward an outermost direction of the semicircular tip part.

An optical adhesive film structure having an alignment function is provided. The optical adhesive film structure includes an optical adhesive layer and a release film. The release film is disposed on the optical adhesive layer. A first film surface of the release film facing away from the optical adhesive layer has a plurality of marks. The marks are recessed into the release film relative to the first film surface and do not run through the release film. A stitching display module and a manufacturing method of the stitching display module are also provided.

A conductive film includes an elongated release film and a plurality of conductive adhesive film pieces provided on the release film. Then, the plurality of adhesive film pieces are arranged in a longitudinal direction X of the release film. For this reason, the adhesive film piece can be set to an arbitrary shape. Accordingly, it is possible to attach the adhesive film piece to adhesive surfaces having various shapes and to efficiently use the adhesive film piece.

The present invention aims to provide an adhesive composition which enables achievement of highly strong adhesion between a lightweight composite resin and a lightweight metal member, and which can maintain excellent adhesive strength even in cases where the ambient temperature largely changes or the adhesive composition is in contact with water or a snow-melting agent, and an adhesive sheet using it. The above object can be achieved with an adhesive composition containing at least an epoxy resin, an acrylic particle, and a curing agent, wherein the acrylic particle is a core-shell structure containing a butadiene-based rubber, and polymethacrylate or polyacrylate. The adhesive sheet is constituted such that an adhesive layer formed with the adhesive composition is present between a first release film and a second release film.

Provided is a pressure-sensitive adhesive sheet that can temporarily fix an adherend in a peelable manner, the pressure-sensitive adhesive sheet being free from requiring high-output laser light irradiation at the time of the peeling of the adherend and being capable of eliminating the need for a step of washing the adherend after the peeling. The pressure-sensitive adhesive sheet of the present invention includes a pressure-sensitive adhesive layer containing a UV absorber and/or a photopolymerization initiator, wherein the pressure-sensitive adhesive sheet has a transmittance of 60% or less for light having a wavelength of 355 nm, and wherein the pressure-sensitive adhesive layer is a layer having an indentation elastic modulus at 23° C. of 25 MPa after irradiation with UV light having an integrated light quantity of 300 mJ/cm.sup.2.

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.
