い。2. Description of the Related Art Rubber adhesives and acrylic adhesives are widely used as adhesives used in patches and the like. However, in both rubber-based adhesives and acrylic-based adhesives, water vapor permeability and water absorbency are poor, and when used as a medical patch, for example, perspiration from the skin does not sufficiently radiate, so the skin is irritated. It was easy to get a rash. Therefore, techniques for making the pressure-sensitive adhesive layer porous or increasing the water vapor permeability of the base material sheet have been adopted as means for improving this problem, but they have not been sufficiently effective.
【０００３】そこで、粘着剤そのものの吸水性を向上さ

水溶性ホットメルト粘着剤が開発されている。これは、
平均重合度３０〜６００、ケン化度４０〜８５モル％の
ポリビニルアルコールと、水溶性可塑剤とからなるもの
である（特開平４−６３８８６号公報参照）。Therefore, a polyvinyl alcohol-based water-soluble hot-melt pressure-sensitive adhesive having improved water absorption of the pressure-sensitive adhesive itself and gradually reducing skin irritation has been developed. this is,
It is composed of polyvinyl alcohol having an average degree of polymerization of 30 to 600 and a degree of saponification of 40 to 85 mol% and a water-soluble plasticizer (see JP-A-4-63886).

いをするという問題があった。However, as in the prior art described in the above publication, the water absorption of the adhesive,
If the hygroscopicity is increased, on the contrary, the cohesive force of the pressure-sensitive adhesive will decrease with time, and a sufficient strength of the adhesive force will not be obtained. There was a problem of thinking.
【０００５】本発明は、上記欠点に鑑みてなされたもの
であり、吸水時に凝集力が低下することのない粘着剤組
成物を提供することを目的とする。The present invention has been made in view of the above-mentioned drawbacks, and an object of the present invention is to provide a pressure-sensitive adhesive composition which does not reduce the cohesive force when absorbing water.

ではない。また、ケン化度が２０モル％以下では親水性
が低下して所期の目的が達成できない。The polyvinyl alcohol used in the present invention has a degree of polymerization of 50 to 250.
It is preferably 0 and the degree of saponification is 20 to 100 mol%.
When the degree of polymerization is less than 50, it is difficult to maintain the cohesiveness of the obtained pressure-sensitive adhesive, and when it exceeds 2,500, the solubility in heating and the solubility in a solvent tend to decrease, which is not practical. If the saponification degree is 20 mol% or less, the hydrophilicity is lowered and the intended purpose cannot be achieved.

The above is preferable. If less than 5 mol%,
It is difficult to maintain the desired cohesive force during water absorption. Examples of the (meth) acrylic acid salt include sodium salts and potassium salts, and sodium salts are preferably used.

100 parts by weight is preferable.

These may be used alone or in combination of two or more.

配慮した上で、個々の粘着付与成分の配合量を実験的に
求める必要がある。The amounts of these tackifying components to be blended cannot be unconditionally determined because the compatibility of the individual tackifying components and the two types of polymers described above is different. However, if the amount of the tackifying component is excessive, the cohesive force tends to decrease, and the coating film tends to bleed out, which is not suitable. On the other hand, when the tackifying component is insufficient, the tackiness is naturally low, and this is not suitable either. Therefore, it is necessary to experimentally determine the blending amount of each tackifying component while taking such a situation into consideration.
