Aspects of the present disclosure provide for composite structures including a bonding layer that adheres a substrate (e.g., including a polymeric composition such as rubber) to a material (e.g., including a polymer such as polyurethane). The adhesion of the substrate to the material through the bonding layer can include chemical bonds such as, but not limited to, siloxane linkages, silanol linkages, silyl linkages, or any combination thereof in the bonding layer.

The present invention refers to a paper article comprising a paper component having a first side and a second side, wherein the first side and/or the second side of the paper component is at least partially coated with a heat-sealable coating, wherein the heat-sealable coating comprises a first polymer comprising units derived from a (meth)acrylate and/or (meth)acrylic acid and/or a salt thereof, and a second polymer, being different from the first polymer, comprising units derived from a) a (meth)acrylate and/or (meth)acrylic acid and/or a salt thereof, and b) an alkene, wherein the first polymer and the second polymer are present in the heat-sealable coating in a weight ratio of 90:10 to 35:65, and wherein the first polymer and the second polymer are present in the heat-sealable coating in an overall amount of at least 50 wt. %, based on the total weight of the coating. Furthermore, the present invention refers to a laminate comprising a paper component, a substrate and a heat-seal layer being present between the paper component and the substrate, which is obtained by heat-sealing a paper article according to the present invention to the substrate. The invention also refers to a use of a coating for heat-sealing a paper component to a substrate.

Provided is an acrylic emulsion pressure-sensitive adhesive composition, and more particularly, an acrylic emulsion pressure-sensitive adhesive composition which may realize excellent adhesive properties, and may maintain excellent adhesive strength even after aging, in particular, when applied to a curved surface of an adherend, and thus may be usefully applied to labels for bottles, etc.

An adhesive tape with high repeelability from the state that a portion of the adhesive tape has already been peeled from an adherend is provided. The adhesive tape includes a substrate layer and an adhesive layer. The substrate layer has a breaking stress in a range of 1 to 90 MPa and an elongation at break in a range of 400% to 3000%. The adhesive tape satisfies the following relational expression (i): [Math. 1] P.sub.400/P.sub.0≤0.9 (i). P.sub.0 denotes an initial cleavage strength N/cm.sup.2 of the adhesive tape, and P.sub.400 denotes a cleavage strength N/cm.sup.2 when the adhesive tape is stretched by 400%.

Provided are adhesive articles that include a silicone adhesive and a substrate, with a primer layer interposed between the silicone adhesive and the substrate. The primer layer includes a polymer having a polyorganosiloxane pendant group P represented by the formula (I) where each R.sup.1 is independently an alkyl, haloalkyl, arylalkyl, alkenyl, aryl, or aryl substituted with an alkyl, alkoxy, or halo; R2 is an alkyl or an alkenyl group; R3 is an alkylene or an arylalkylene group; and n is an integer in the range of 1 to 20. The primer layer typically improves the adhesion between the silicone adhesive and a wide variety of substrates.
