[0149] Preparation of Example 1

[0150] Preparation of acrylic adhesive.

[0151] 156 g of butyl acrylate, 22.5 g of 1-vinylimidazole, 1.13 g of acrylic acid, and 90 g of styrene macromonomer were successively added into a 2000 ml separable flask. Next, 0.27 g of 2,2'-azobis(2,4-dimethylvaleronitrile) and 480 g of ethyl acetate were put thereinto. The polymerization reaction was carried out for 8 hours in a normal temperature water container kept at 50° C. while blowing nitrogen gas from the lower part of the blended solution with a Pasteur pipette.

Abstract

To provide an adhesive tape which can be stretched so as to be easily removed entirely from an adherend through one time of a pulling operation, leaving the adhesive little on the adherend, lending itself well to be stuck to various materials inclusive of a soft vinyl chloride, and can be strongly adhered even to adherends having a rugged structure in the surface thereof following up the shape to a sufficient degree. The adhesive tape comprises a pair of a first adhesive element having a first adhesive layer directly applied to an adherend and a second adhesive element, capable of being stretched, including a second adhesive layer applied to the adherend via the first adhesive layer and a base member that supports the second adhesive layer, wherein the first adhesive layer has the strain and stress smaller than the strain and stress of the second adhesive element as measured by a tensile test.

Description

Background technique [0001] This invention relates to adhesive tapes. More particularly, the present invention relates to peelable adhesive tapes which, after having been adhered to a material or an adherend, can be easily removed (as required) from the material without leaving any residue on the material. Adhesive, which does not cause any substantial damage to the material, and which can also be applied to any material including soft vinyl chloride, and even conforms to materials with rough textures on the surface in order to bond strongly thereto. The invention also relates to an article attachment kit having an adhesive strip. [0002] Various types of adhesive films and adhesive inserts or so-called adhesive tapes have been proposed and put into practical use to meet various objectives. As adhesive tapes characterized by, for example, peeling properties, adhesive tapes that can be stretched and removed without damaging the adhesive material have come into practical use ...
