An optical-fiber-embedding sheet which is a strip-shaped sheet material containing an optical fiber to be used as a sensor and is configured of a base material and an adhesive layer formed thereover which is to be bonded to a placement object where the optical fiber is to be placed, the optical fiber having been embedded in the adhesive layer. The optical fiber is placed by applying a primer, which is for curing the adhesive layer by a chemical reaction with the adhesive layer, to a placement object for the optical fiber and thereafter applying the optical-fiber-embedding sheet to the portion of the placement object to which the primer has been applied.

A polyester pressure-sensitive adhesive composition is provided including a polyester resin having a predetermined amount of a structural unit derived from a hydrogenated polybutadiene structure-containing compound, or a polyester resin having a structural unit derived from a hydrogenated polybutadiene structure-containing compound and a predetermined amount of a structural unit derived from an aromatic ring structure-containing compound. The polyester pressure-sensitive adhesive composition has superior adhesion to a polyolefin base material and is highly transparency.

The present specification relates to a method for manufacturing a polarizing plate using a mask film used for manufacturing a polarizing plate having a locally bleached area, and a polarizing plate manufactured using the same.

A dam forming method and a method for manufacturing a laminate capable of suppressing the occurrence of a height difference in the thickness of a dam. A dam forming method is used in a method for manufacturing a laminate in which a first base member and a second base member are laminated via a fill material, including: forming a dam surrounding an application region for the fill material on the first base member; and applying the fill material to the application region. The dam forming method includes: applying a dam-forming resin composition on peripheral edges of the first base member by accelerating the application speed of the dam-forming resin composition continuously or stepwise from the start to the end of the application; and curing the applied dam-forming resin composition.

An optical assembly includes an optically transparent substrate and a first lens removably coupled with the optically transparent substrate by one or more adhesive layers. The one or more adhesive layers are positioned between the optically transparent substrate and the first lens. Also disclosed are an eye-tracker and a display device, each of which includes the optical assembly.

An apparatus includes one or more stamps configured to install an optical fiber on a surface of a structure. Each stamp includes a backing. A first adhesive is disposed on one or more first regions of the backing and is configured to provide a temporary bond between the optical fiber and the surface. A second adhesive is disposed on at least a second region of the backing and is configured to provide a substantially permanent bond between the optical fiber and the surface. A liner is removably adhered to the first adhesive.

In one or more embodiments, a luminaire includes a housing, a light source coupled with the housing, an optical sheet coupled with the housing, and a film stabilizer coupled with the housing. The optical sheet includes a first surface and an opposing second surface that are both disposed substantially horizontally when the luminaire is in an installed orientation. The first surface is disposed facing the light source, so that when the light source emits light, the light passes first through the first surface and subsequently through the second surface. The film stabilizer includes a third surface and an opposing fourth surface. The film stabilizer is disposed with the third surface adjacent to the second surface of the optical sheet, and provides mechanical support for the optical sheet.

This method of laminating a functional film onto an optical article includes: thermoforming the functional film so as to provide the functional film with a predetermined target curvature based on a curvature of a face of the optical article on which the functional film is to be applied; applying the functional film onto that face of the optical article; pressing the functional film against that face of the optical article so as to adhere the functional film to that face of the optical article. This method further includes heating the functional film at at least one predetermined temperature after the applying, so that the functional film conforms to the curvature of that face of the optical article.

The invention relates to a scaled holographic medium comprising a layer construction B′-C1′-C2′, to a process for producing the sealed holographic medium, to a kit of parts, to a layer construction comprising a protective layer and a substrate layer and to the use thereof.

The present disclosure relates to a method of preparing a laminate or a laminated lens, comprising obtaining a first plastic substrate having a front surface and a back surface, treating the front surface of the first plastic substrate or the back surface of the first plastic substrate, and laminating a second plastic substrate on the treated front surface of the first plastic substrate or the treated back surface of the first plastic substrate. The treating may include applying a polyurethane resin to a surface of the first plastic substrate. The method may further comprise treating a surface of the second plastic substrate. The method may further comprise applying activator to the treated surfaces of the first plastic substrate and the second plastic substrate and laminating by apposing the treated surfaces of the first plastic substrate and the second plastic substrate.
