Problems solved by technology

However, the film has problems such as the use of an organic solvent when the antistatic layer is formed, making the process complicated and economically unfavorable since measures to prevent environmental pollution are required
This film has another problem, even if the antistatic layer is formed as an intermediate layer, the antistatic effect is not enough, especially on a sheet support

Abstract

The invention provides a molding material which is excellent in antistatic properties and molding appearance and preferably excellent also in transparency and heat resistance and is usable as a molding material for the pressure-sensitive adhesive layer and substrate of a pressure-sensitive adhesive film. An antistatic resin composition which comprises (A) a polyolefin resin, (B) a block copolymer comprising an olefin polymer block and a hydrophilic polymer block, and (C) at least one polymer selected from the group consisting of polymers containing conjugated diene compound units and products of hydrogenation of the polymers. Tackiness can be controlled by regulating the amount of the ingredient (A) to be incorporated. When the ingredient (A) comprises a polyolefin resin containing cycloolefin units and having a glass transition temperature of 60-200 DEG C, heat resistance is improved. Preferred examples of the ingredient (C) are a block copolymer comprising a polymer block of a conjugated diene compound and a polymer block of an aromatic vinyl compound and a product of hydrogenation of this block copolymer.

Description

technical field [0001] The present invention relates to an antistatic resin composition for imparting excellent antistatic properties to molded articles such as films and sheets, antistatic / pressure-sensitive adhesive properties suitable for forming highly antistatic adhesive layers on molded articles such as films and sheets Resin composition, pressure-sensitive adhesive film having an antistatic adhesive layer comprising an antistatic / pressure-sensitive adhesive resin composition, and methods for their preparation. More specifically, the present invention relates to an antistatic resin composition which has excellent antistatic properties and transparency, and which also has an excellent surface appearance when formed into a molded article such as a film, and to an antistatic / pressure-sensitive adhesive resin composition, It is excellent in antistatic properties and tackiness, and the adhesive strength is easy to control, and relates to molded articles such as pressure-sensi...
