The present invention relates to an adhesive composition containing a polymer and an ionic liquid, in which an exudation amount of the ionic liquid is 0.002 mg/cm.sup.2 or more when an adhesive layer formed of the adhesive composition is allowed to adhere to an adherend and then is debonded after applying a voltage of 10 V for 10 seconds.

An adhesive film including a first adhesive layer, wherein the first adhesive layer contains a first adhesive component and a plurality of conductive particles, wherein the plurality of conductive particles include first conductive particles that are dendritic conductive particles, and second conductive particles that are conductive particles other than the first conductive particles, each conductive particle containing a non-conductive core and a conductive layer provided on the core, and a part of the plurality of conductive particles is disposed to protrude from one surface of the first adhesive layer.

A threadlike adhesive sticking apparatus of the present invention is a threadlike adhesive sticking apparatus configured to press a threadlike adhesive wound in a roll shape together with a release liner against an object while feeding out the threadlike adhesive, and includes a pressing unit configured to press the threadlike adhesive debonded from the release liner against the object. A compression elastic modulus of the release liner is 1.5 MPa or less.

A threadlike adhesive sticking apparatus of the present invention includes a nozzle having an inner wall surface defining a cylindrical internal space and a tip end having a tip end opening allowing the internal space to communicate with the outside at one end of the inner wall surface, and a plurality of portions of a peripheral portion surrounding the tip end opening at the tip end function as a pressing unit that presses a threadlike adhesive, which has been allowed to pass through the internal space and has been led out to the outside from the tip end opening, against an object.

A support film for a tape material, includes a film-shaped support formed of polyurethane; and a barrier layer containing an aromatic isocyanate-based polyurethane and a layered inorganic compound and formed on one surface of the support.

To provide a PSA sheet having excellent IR-blocking properties. Provided is a PSA sheet having a PSA layer. The PSA sheet has 5% or lower light transmittance in the thickness direction in a wavelength region of 780 nm to 2500 nm. The PSA sheet has 0.01% or lower light transmittance in an in-plane direction in a wavelength region of 380 nm to 2500 nm.

Provided is a PSA sheet having limited light transmission, an increased refractive index and good adhesive properties. The PSA sheet provided by this invention has a PSA layer. The PSA sheet has a total light transmittance below 80%. The PSA layer has a first face and a second face on the opposite side to the first face. The PSA layer comprises high-refractive-index particles. In the PSA layer, the high-refractive-index particles are concentrated in a range that extends from the first face towards the second face side and has a thickness of at least 100 nm, accounting for less than 50% of the PSA layer thickness.

The invention relates to a method for forming an article comprising a pathway of particles wherein a termination of the pathway of particles is exposed. The method comprises arranging the particles by applying an electric field and/or a magnetic field at an interface between a water soluble or a non-water soluble matrix and a matrix comprising a viscous material and particles. After fixating the viscous material, the termination is exposed by dissolving the water soluble or non-water soluble matrix. The invention also relates to articles obtainable by said method, and to the use of said method in various applications.

A viscosity modifier is thermally stable and can provide an excellent viscosity-increasing effect and/or an anti-sagging effect, and is used by the addition to a paint, a coating agent, a painting agent, a flux, an adhesive material, and a sealing material that are produced/used under high temperature conditions. A film-forming agent contains the viscosity modifier including a polyamide component that contains a polyamide compound from a C2-10 aliphatic and/or C6-10 aromatic primary diamine and a C12-36 polybasic acid and/or a C12-30 unsubstituted or hydroxy-substituted aliphatic monocarboxylic acid. The film-forming agent contains the viscosity modifier and a film-forming component and is at least any one selected from a paint, a coating material, a painting material, a flux, an adhesive material, and a sealing material.
