Description of the Related Art Heretofore, as a natural rubber-based pressure-sensitive adhesive composition containing a natural rubber in a latex state, a composition in which a natural rubber latex prepared for industrial use is directly blended has been known. However, in order to break down the natural rubber latex and make it compatible with tackifier and the like to develop practical adhesive properties, high temperature treatment is required and film forming properties are poor, so that an adhesive layer is provided on the support. Has a problem that a large amount of energy is required by high-temperature drying. In addition, it is inferior in various properties such as adhesive properties, water resistance, electric insulation, etc. as compared with those prepared in a solution system using a solvent, and therefore has excellent safety such as environmental hygiene and disaster prevention by not using a solvent. Nevertheless, it is not currently used.

Was determined. That is, a commercially available natural rubber latex obtained as a sap or the like contains a few percent of protein, which functions as an emulsifier to form a latex state. It was clarified that it required high temperature for destruction and reduced film-forming properties because it was a body.

Moreover, surprisingly, it is a latex and has excellent electrical insulation. This is probably because the protein is easily charged and has been removed.

In the form of a latex.
When the content of the protein exceeds 0.1% by weight based on nitrogen, the improvement effect is hardly exhibited. The preferred protein content is 0.05% by weight or less based on its nitrogen.

The protein may be removed from the natural rubber by an appropriate method such as a method of treating with a protease.
