く、作業のスムーズな進行を阻害する問題点があった。However, there is a problem in that the self-adhesiveness is poor, because the adhesive force with the adherend may be stronger. Therefore, the binding portion between the adhesive surfaces may be easily peeled off by the action of the impact force. In addition, there was a problem that the cutter suitability was poor.
That is, there is a problem in that the residue of the adhesive is likely to be deposited on the cutter blade portion in the cutting operation of the tape cutter, which is used as the adhesive member, and the smooth progress of the operation is hindered.

いる。By adding a chelate compound of a resin coordination consisting of an alkaline earth metal, it is possible to improve the self-adhesive force of a pressure-sensitive adhesive using a block copolymer of a monovinyl-substituted aromatic compound and a conjugated diene compound as a base polymer, And in most cases, the adhesive force to the adherend can be reduced. Thereby, the adhesive force between the adhesive surfaces can be made larger than the adhesive force with respect to the adherend. In addition, cutter suitability can be improved. The present inventors believe that this action is due to the fact that the system is softened by the compatibility of the chelate compound, which improves self-adhesiveness, and the adhesive force is easily broken due to a decrease in the interaction force of the base polymers. thinking.

しく用いられる。The self-adhesive pressure sensitive adhesive of the present invention contains a chelate compound. As the chelate compound, a resin coordination type compound made of an alkaline earth metal is used. Such a chelate compound can be obtained, for example, by reacting an oxide of an alkaline earth metal such as magnesium, calcium, strontium, or barium with a resin having a functional group such as a hydroxyl group or a methylol group. As the resin,
For example, a phenol resin, a rosin resin, a coumarone resin, etc. are used, and among them, an alkylphenol resin is preferably used.

しい。A suitable amount of the chelate compound is 5 parts by weight or more per 100 parts by weight of the base polymer. If the blending amount is less than 5 parts by weight, the effect of improving self-adhesiveness and cutter suitability is poor.
On the other hand, if the blending amount exceeds 100 parts by weight, the self-adhesiveness may be impaired, and from this point, the blending amount of 50 parts by weight or less is preferable.

A suitable amount of the tackifier is 20 parts by weight or less per 100 parts by weight of the base polymer. If the blending amount is large, the adhesive force to the adherend may become too large. The tackifier used has a softening point of 40 ° C. or higher, preferably 60 to 180 ° C., and is solid or semi-solid at room temperature. Generally, one or more terpene-based resins, terpene-phenolic or aromatic-based resins, phenol-based resins, coumarone-indene-based resins, xylene-based resins, rosin-based resins, petroleum-based resins and the like are used. As other additives, customary ones such as a softening agent, a plasticizer, an antioxidant, an ultraviolet absorber, a filler, a pigment and a filler are used. These are appropriately blended within a range that does not reduce self-adhesiveness and suitability for a cutter.

質と同様、特に限定はない。The pressure-sensitive adhesive member of the present invention is one in which a pressure-sensitive adhesive layer made of the above-mentioned self-adhesive pressure-sensitive adhesive is attached to a supporting substrate. To form the adhesive member, for example, a method of dissolving a self-adhesive adhesive in a suitable solvent such as toluene or heptane and coating it on a supporting substrate, an extrusion melt coating method, a roll coating method using a calendar roll, or the like. A suitable method for attaching an adhesive layer may be applied, such as a method of applying a solvent-free coating to the supporting substrate with a method of laminating a separately formed adhesive layer on the supporting substrate. The pressure-sensitive adhesive member may be formed in any desired form, such as an overall coating on one or both sides of the supporting substrate, or a partial coating such as streaks or dots. Appropriate ones are used for the supporting substrate, and generally polypropylene, polyester,
Films made of plastics such as polyvinyl chloride and polyethylene, kraft paper, papers such as Japanese paper, woven cloth,
Cloths such as non-woven fabrics, metal foils, foams, etc. are selected and used according to the purpose of use. The thickness is generally 5 to 500 μm, but it may exceed 1 mm for protection purposes and the like, and the material thereof is not particularly limited.
