<p>A strippable pressure-sensitive adhesive and an adhesive material using the same are disclosed, said adhesive comprising a highly elastic base polymer whose dynamic modulus of elasticity is in the range of from 250,000 to 10,000,000 dyne/cm<2> at a temperature between ambient temperature and 150 DEG C with a small rate of change with temperature, having incorporated therein a blowing agent, which adhesive reduces or loses its adhesiveness on expansion or blowing of said blowing agent. The adhesive and adhesive material are easily re-applied, is capable of satisfactorily following the shape of an adherent during forming of the adherent, reduces its adhesiveness on heating, and is applicable to various adherents with excellent workability.</p> |
