PURPOSE: To prevent the trouble by the electrification on the surface of the adhesive of the adhesive label constituted of a base, an adhesive layer and release sheet in this order by mixing a conducting agent with the adhesive layer.
CONSTITUTION: The conducting agent to be mixed with the adhesive layer includes an electron conductive material and an ion conductive material, both of which are usable. Examples of the electron conductive material include metallic powder, metal oxide and carbon black. Conductive particulates formed by adhering the electron conductive material to the surfaces of flat shaped particulates of mica, etc., and acicular particles, such as whiskers are used as well. These electron conductive materials are added at 2 to 10wt.% of the solid content of the adhesive. Both inorg. and org. materials are usable as the ion conductive material. The representative example of the org. material is a metal salt. The org. materials include an anion system and cation system. These ion conductive materials are added at 5 to 20wt.% of the solid content of the adhesive. As a result, the peeling and electrification are prevented.
