The present disclosure relates to an adhesive film, and adhesive film includes: a photothermal conversion layer including a light absorbing agent and a pyrolytic resin; an adhesive base film layer disposed on the photothermal conversion layer; a buffer layer disposed on the adhesive base film layer; and an adhesive layer disposed on the buffer layer, and the buffer layer includes a polysiloxane resin, and the adhesive layer includes a silicon-based adhesive, and the silicon-based adhesive includes a silicon-based tackifier and a polysiloxane resin. The adhesive film according to the present disclosure can simplify a process of processing a substrate, and can prevent a damage of the substrate and a circuit or an element formed on the substrate.

A protective film includes an adhesive material configured for “dry” application to a surface that is to be protected, such as the surface of an electronic device. An installation assembly that includes the protective film is configured to minimize or eliminate contact with the protective film as it is applied to the surface that is to be protected. Methods for manufacturing a protective film and an installation assembly that includes the protective film may be effected in contaminant-free conditions. Methods for applying the protective film are also disclosed, as are device (e.g., electronic devices, etc.) with at least one surface covered with a protective film.

A back grinding tape including a hard coating layer, an intermediate layer including a polyurethane-based resin, and an adhesive layer provided has an excellent water resistance, thus easily protecting patterns, and has an excellent adhesion between each layer, and thus each layer is not separated in the process of removing the tape, such that the back grinding tape is suitable for a back grinding process.

A pressure-sensitive adhesive tape that uses, as a plasticizer, an alternative compound to bis(2-ethylhexyl) phthalate (DOP) and dibutyl phthalate (DBP), having excellent tackiness, and can be unwound satisfactorily, where DOP and DBP are to be restricted under the REACH regulation. The pressure-sensitive adhesive tape includes a poly(vinyl chloride) substrate and a pressure-sensitive adhesive layer. The pressure-sensitive adhesive layer is disposed on or over one side of the substrate. The poly(vinyl chloride) substrate contains 10 to 40 percent by weight of bis(2-ethylhexyl) terephthalate. The pressure-sensitive adhesive tape preferably has an unwinding force of 0.4 N/20 mm or less at a tensile speed of 0.3 m/min and an unwinding force of 1.2 N/20 mm or less at a tensile speed of 30 m/min.

Provided are an electromagnetic wave absorbing sheet which is a thin film and a low cost and has an excellent electromagnetic wave absorbing rate, a method of manufacturing the same, and an electronic device using the same. The electromagnetic wave absorbing sheet includes: at least one layer thin-film magnetic sheet which is separated into a plurality of fine pieces; a protective film that is adhered on one surface of the thin-film magnetic sheet; and a double-sided tape that is adhered on the other surface of the thin-film magnetic sheet.

An adhesive article for masking a portion of a substrate surface from a liquid coating applied to the surface includes a support having first and second opposed major surfaces, and a cationic or zwitterionic adhesive composition disposed on at least a portion of at least one of the first and second opposed major surfaces. The adhesive composition provides a barrier that impedes the migration of the coating past the edge of the adhesive article.

A label having a silicone-free (water-based) release coating and compatible adhesive patch is provided. The label includes a thermally coated substrate having a silicone-free substrate overlaid thereon of a first surface. A second surface includes a microsphere adhesive layer.

Compositions which are well suited for forming into machine direction orientation (MDO) films are described. Multilayer films containing one or more layers of the compositions and/or films are also described. Additionally, label assemblies utilizing the multilayer films, labeled substrates, and related methods are described. Various versions of the multilayer films are described including films having at least two skin layers and an interior core layer. Particular multilayer films are described having polyethylene rich cores.

Methods and apparatus to vent gas and vapor from a panel via venting channels for a decorative layer are disclosed. An example apparatus includes a decorative layer, an adhesive layer to couple the decorative layer to a panel, and a resin layer disposed between the decorative layer and the adhesive layer. The adhesive layer is coupled to a first side of the resin layer. The decorative layer is coupled to a second side of the resin layer. The first side of the resin layer defines venting channels to vent at least one of gas or vapor away from the decorative layer to deter the at least one of gas or vapor from exerting a pressure on the decorative layer to deter separation of a portion of the decorative layer from the resin layer. The venting channels have a depth to impede the adhesive layer from filling the venting channels.

The purpose of the present invention is to provide a transfer sheet capable of providing hard coat properties and excellent weather resistance to a resin molded article such as organic glass. The transfer sheet has, in order, a base material film for mold release, a hard coat layer, a primer layer, and an adhesive layer. The weather resistance and adhesiveness of the hard coat layer and the primer layer are improved and hard coat properties and excellent weather resistance can be provided to a resin molded article being the transfer object, as a result of: the hard coat layer being formed from a cured product of a resin composition including a curable resin; and the primer layer being formed from a binder resin including a polyurethane having a mass-average molecular weight of 40,000-100,000 and including 1-30% by mass of an acrylic component.
