A decorative multi-layer covering for horizontal and vertical surfaces such as floors and walls, having a decorative layer provided with decorative motifs visible from the outside, a support layer and a self-adhesive layer to be placed on the surface to be covered. The self-adhesive layer has a perforated foam material layer with an outer surface provided with an adhesive. The perforated surface of the foam material layer has between 5% and 95%, and more preferably between 15% and 50%, of the entire surface of one of the two faces of the support layer, which is distributed over several perforations. A stabilising layer can be arranged between the support layer and the self-adhesive foam material layer, the perforations connecting to the lower face of the stabilising layer.

The present disclosure provides adhesive mounting articles that can be removed from surfaces without damage by having reduced contribution of a hardgood to the peel force generated by the adhesive article during removal. In some instances, this can be accomplished by a hardgood that is flexible in a peel direction and rigid in a weight hanging direction. Such hardgoods may include a plurality of minimally connected body segments arranged about the transverse axis of the hardgood body.

The invention pertains in a first aspect to a multilayer film that includes a frangible holographic image layer and an adhesive layer adjacent to a side of the holographic image layer; and, an additional temporary support layer that is adjacent a side of the holographic image layer that is opposite the adhesive layer, and provides integrity to the multilayer film. The additional temporary support layer can be a polyester film that is removable from the multilayer film at 10 gram per inch peel strength; or, can be a heat-shrinkable film that is removable from the multilayer film with the application of heat. After application of the multilayer film to a substrate, the holographic image layer forms an exterior surface of the multilayer film. In a second aspect, the invention pertains to an authentication label of the multilayer film for attachment to a substrate, wherein a side of the adhesive layer that is opposite the holographic image layer contacts the substrate, and the holographic image layer forms an exterior surface of the label.

The present invention provides a heat shrinkable multilayer film which has excellent adhesiveness between front and back layers and an interlayer not only at normal temperature but also at low temperature to effectively prevent delamination and is less likely to have residual white streaks along creases. The present invention also provides a heat shrinkable label including the heat shrinkable multilayer film. The present invention relates to a heat shrinkable multilayer film including: front and back layers each containing a polyester resin; an interlayer containing a polystyrene resin; and adhesive layers, the front and back layers and the interlayer being stacked with the adhesive layers interposed therebetween, the adhesive layers each containing 20 to 65% by weight of a polystyrene resin and 35 to 80% by weight of a polyester elastomer.

An adhesive composition is provided which exhibits an excellent adhesion rate on metals and low-polarity thermoplastic elastomers, and is excellent in appearance with no clouding of hardened bodies and is good in storage stability. It is a 2-cyanoacrylate-based adhesive composition which includes (a) a 2-cyanoacrylic acid ester and (b) an onium salt represented by the general formula: C.sup.+A.sup.(1) where, in formula (1), C.sup.+ represents an onium cation, and A.sup. represents a bis(fluorosulfonyl)imide anion.

The present invention relates to an adhesive compositions, facestocks and/or packaging labels containing same, where such compositions, facestocks and/or labels are designed to facilitate the recyclability of a plastic article formed from any suitable polymer or mixture of polymers (e.g., a polyethylene terephthalate (PET), high density polyethylene (HDPE), polyvinyl chloride (PVC), low density polyethylene (LDPE), polypropylene (PP), polystyrene (PS), or others of all plastic types), or even glass bottles. In another embodiment, the present invention relates to a method for removing an adhesive composition, facestock and/or packaging label containing same, from a plastic article that is to be recycled.

Provided is a back grinding adhesive sheet which can adequately protect protrusions provided to a semiconductor wafer, and with which back grinding can be adequately performed. The present invention provides a back grinding adhesive sheet for a semiconductor wafer having protrusions, the back grinding adhesive sheet comprising a non-adhesive cushion layer, and an adhesive layer provided on the cushion layer. The adhesive layer has an opening with a smaller diameter than the diameter of the semiconductor wafer, and the outer edge of the semiconductor wafer is adhered to the adhesive layer such that the protrusions on the semiconductor wafer are positioned inside the opening. The protrusions are protected by the cushion layer when the semiconductor wafer is in the state of being adhered to the adhesive layer. The adhesive sheet satisfies at least one of the following conditions (1)-(2). (1) When the cushion layer is cut out using the dumbbell from JISZ1702 and is stretched 25% at a gauge length of 40 mm and a tensile speed of 300 mm/min, the tensile stress is 2-30N/10 mm. (2) The cushion layer is formed from a thermoplastic resin that has a melt flow rate (JISK7210, 125 C./10.0 kg load) of 0.2-30 g/10 min, and a melting point of 60-110 C.

Hybrid fibers or filaments are extruded from a granulate mixture of bio-based polymers with petrochemical-based plastic polymers to form a textile substrate band and the band is then provided with an adhesive coating on at least one face of the substrate band to form an adhesive tape. This tape is then wound helically around a cable bundle to form a longitudinally extending wrap of the bundle and impart to the cable bundle an abrasion resistance of at least class C according to LV 319 (2009).

According to the invention, a dicing film, which generates a small amount of scrapes and beard-like burrs during dicing and furthermore has desirable strength and external appearance, is provided. The dicing film according to the invention has an adhesive layer on at least one surface of a base film, wherein the base film contains a copolymer (A) of at least two kinds of alkyl(meth)acrylates and styrene; and a styrene-based elastomer (B). The copolymer (A) of at least two kinds of alkyl(meth)acrylates and styrene is a styrene-alkyl methacrylate-alkyl acrylate copolymer.
