阻害を避ける手段となるものではない。It is necessary that the adhesiveness to the vulcanized rubber molded product is excellent in the initial adhesiveness and the adhesive force is not lowered by the bleeding substance from the vulcanized rubber molded product. In the adhesive composition described in the above publication, it is necessary to use three components of a quinonedioxime compound, a peroxide and a redox catalyst as a cross-linking agent in a fixed ratio. If the ratio is out of this range, the crosslinking reaction will not proceed or the crosslinking will be excessive, resulting in poor anchoring to the adherend and poor adhesive properties. Thus, it is difficult to balance the type and amount of the cross-linking agent, and it is not a means for avoiding the inhibition of adhesion of the vulcanized rubber molded product due to the bleeding substance.

ぐれた粘着力を示すことになる。The pressure-sensitive adhesive composition of the present invention has the above-mentioned constitution, and the tackifying resin is blended in the mixture of butyl rubber and liquid isoprene rubber, and since the rubber component is not crosslinked, the wettability to the adherend is high. It improves and has excellent initial adhesion. In addition, after the initial adhesiveness is exhibited, the pressure-sensitive adhesive gradually crosslinks due to the metal oxides and substances having various functional groups which migrate to the pressure-sensitive adhesive layer. Therefore, the cohesive force of the pressure-sensitive adhesive is improved to prevent the pressure-sensitive adhesive force from decreasing, and the pressure-sensitive adhesive exhibits excellent long-term pressure-sensitive adhesive force.
