A shield that is attachable to a touch sensitive screen is disclosed. The shield may be attached to the touch sensitive screen only at its outer peripheral portion. An air gap is enclosed between the shield and the touch sensitive screen to form a planar air bearing. The shield preferably does not touch the active area of the touch sensitive screen when the user is not touching the shield but only viewing the touch sensitive screen through the shield. This mitigates unwanted optical artifacts such as trapped air bubbles, Newton rings and chromatic interference while maintaining the sensitivity of the touch sensitive screen.

An adhesive material that provides fast and robust adhesion on wet surfaces, where the adhesion formed is detachable on-demand. The adhesive material is formed of one or more hydrophilic polymers or copolymers grafted with one or more amine coupling groups via a plurality of cleavable physical bonds and/or cleavable covalent bonds and one or more cross linkers. Application of the adhesive material on a wet surface causes the adhesive material to absorb liquid to thereby swell the adhesive material to form a layer of hydrogel, resulting in the formation of temporary crosslinks followed by covalent crosslinks with the surface. Introducing a triggering agent cleaves the cleavable physical bonds and/or cleavable covalent bonds to allow for non-traumatic detachment of the adhesive material from the surface.

A screen protector for protecting a screen of an electronic device is provided. The screen protector includes a transparent substrate having a first side and a second side opposite the first side, a first removable film covering the first side of the transparent substrate and a second removable film covering the second side of the transparent substrate, and a first alignment assistance tab positioned on the second removable film, wherein the first alignment assistance tab includes an affixing portion attaching the first alignment assistance tab to the second removable film and a user grip portion extending outwardly from the affixing portion.

A polymeric tape comprises a facestock extending lengthwise, the facestock including a polymer. An adhesive layer is on a first surface of the facestock. Tear-cuts are formed into at least one longitudinal edge of the facestock and extending inwardly, the tear-cuts being provided all along the at least one longitudinal edge of the facestock.

An object of the present invention is to provide a polymer that has excellent heat resistance and dielectric properties and can be dissolved in an organic solvent at a high concentration, a resin composition containing the same, and a molded body thereof. The polymer of the present invention has a repeating unit derived from a polymerizable compound of the following formula (I) (In the formula, X.sup.1 and X.sup.2 each independently represent a C3 to C6 branched alkyl group, a C3 to C6 cyclic alkyl group, a C3 to C6 branched alkoxy group, or a C3 to C6 cyclic alkoxy group, n represents 0 or 1, Z.sup.1 and Z.sup.2 each independently represent a single bond or a C1 to C3 alkylene group, each R independently represents an organic group or a halogeno group, m1 and m2 each independently represent any integer of 0 to 4, and Y represents a polymerizable functional group).

The present invention aims to provide an adhesive tape having excellent adhesion and exhibiting excellent holding power even under prolonged shear stress at high temperature. Provided is an adhesive tape including an adhesive layer, the adhesive layer containing an acrylic copolymer containing a structural unit derived from an alkyl (meth)acrylate and a structural unit derived from an olefin polymer having a polymerizable unsaturated double bond at an end, the adhesive layer having a swelling ratio of 40 or greater and 500 or less when immersed in tetrahydrofuran at a temperature of 25 C. for 24 hours.

A composite film includes a first thermoplastic elastomer film layer and a second thermoplastic elastomer film layer, wherein the first thermoplastic elastomer film layer includes a first styrenic block copolymer. The second thermoplastic elastomer film layer is disposed on the first thermoplastic elastomer film layer, wherein the second thermoplastic elastomer film layer includes a second styrenic block copolymer, diffusion particles dispersed in the second thermoplastic elastomer film layer, and a surface microstructure disposed on the surface of the second thermoplastic elastomer film layer.
