Embodiments provide a pressure-sensitive adhesive film having (α) a poly(meth)acrylimide-based resin film layer and (γ) a pressure-sensitive adhesive agent layer in that order from the surface layer side and having a total light transmittance of 80% or higher. The pressure-sensitive adhesive film may further have (δ) a hard coat layer on the surface layer side of the poly(meth)acrylimide-based resin film layer (α). This hard coat layer (δ) may comprise an active energy ray-curable resin composition that contains (A) 100 parts by mass of a polyfunctional (meth)acrylate; (B) 0.2-4 parts by mass of a compound having an alkoxysilyl group and a (meth)acryloyl group; (C) 0.05-3 parts by mass of organic titanium; and (D) 5-100 parts by mass of fine particles having an average particle diameter of 1-300 nm. This active energy ray-curable resin composition may further contain (E) 0.01-7 parts by mass of a water-repelling agent.

A method of manufacturing decoration foils and a release layer and an adhesive layer of the decoration foil, and decoration foils manufactured by the same are revealed. First take waste containing polyethylene terephthalate (PET) to react with an alcohol and get a first product. Then the first product is allowed to react with a compound containing isocyanate group and polyol to obtain polyurethane (PU) material. The PU material obtained is used for manufacturing at least one of a release layer and an adhesive of decoration foils to get the decoration foil.

Provided are a filling film and a method of manufacturing an organic light-emitting display apparatus by using the filling film. The filling film includes a filling material, a first releasing film attached to a surface of the filling film, a second releasing film attached to another surface of the filling film, and a supporting layer attached to the second releasing film. The bonding force between the second releasing film and the supporting layer is greater than the bonding force between the filling material and the second releasing film.

A cellulosic fiber-based adhesive tape substrate, at least one side of which is coated with an aqueous mixture of: a) at least one organic polymer having pendant groups with at least one vinyl function; b) at least one polysiloxane comprising at least one hydrogenosiloxane monomer —(O—SiR.sup.1H)—, wherein R.sup.1 is a linear or branched and/or cyclic hydrocarbon chain which may contain heteroatoms; c) at least one hydrosilylation catalyst.

A cellulose fiber-based substrate, at least one side of which is coated with an aqueous mixture composed of: a) at least one water-soluble polymer (WSP) containing hydroxyl groups, b) at least one lactone substituted with at least one linear or branched and/or cyclic C.sub.8-C.sub.30 hydrocarbon chain which may contain heteroatoms, c)at least one crosslinking agent. A method of production and use thereof.

This disclosure discloses an adhesive tape having a dimension in a thickness direction, comprising a tape base layer, an adhesive layer, and a separation layer. The adhesive layer is disposed on one side of the tape base layer in the thickness direction and includes a predetermined adhesive. The separation layer is disposed on the other side of the tape base layer in the thickness direction and includes a silicon separating agent, an olefin resin separating agent, or an acrylic resin separating agent having a long-chain alkyl group.

Provided is a pressure sensitive adhesive sheet for tires that enables continuous and efficient labeling on tires using a labeling apparatus. The pressure sensitive adhesive sheet includes a release material (C), a first pressure sensitive adhesive layer (B1), a first substrate (A1), a second pressure sensitive adhesive layer (B2), and a second substrate (A2), in this order, and satisfies Requirement (1): in a planar view of the pressure sensitive adhesive sheet, the outline of the first pressure sensitive adhesive layer (B1) exists inside the outline of the second substrate (A2); and Requirement (2): the MD stiffness of the second substrate (A2), measured in the Gurley method according to JIS L 1085, is 0.10 mN or more.

The present disclosure belongs to the technical field of disposable toilet seat covers, and in particular to a novel portable toilet seat cover. The novel portable toilet seat cover comprises more than one unit layers, each unit layer comprises a surface layer, and a base layer. The surface layer is arranged at a first surface of the base layer, and the bottom layer is arranged at a second surface of the base layer; the surface layer is a release layer for preventing skin adhesion.

A cling foil comprising an outermost adhesive layer comprising a pressure sensitive adhesive, an outermost release layer, the outermost release layer comprising a release material, and a foil layer positioned between the outermost adhesive layer and the outermost release layer.

A multilayer tape assembly is described which can be used with insulation jacketing and particularly for self sealing lap (SSL) applications. The tape assembly includes two adhesive layers with associated carrier and release layers in conjunction with a differential release system. Various methods of use are also described.
