PURPOSE: To improve shape holdability and absorptivity by using natural rubber as a buffer and alkyl cellulose, water-soluble high-polymer compd. and highly water-absorptive resin as a bleeding liquid absorbent and laminating a water- absorptive adhesive layer formed by compounding the mixture composed thereof and a pressure sensitive adhesive on the base of a foam.

CONSTITUTION: The natural rubber to be used as the buffer includes gua rubber, etc., and the compounding amt. thereof is 5 to 50w/w%. The alkyl cellulose to be used as the bleeding liquid absorbent includes carboxymethyl-cellulose and the compounding amt. thereof is 3 to 50w/w%. The water-soluble high- polymer compd. to be used as the bleeding liquid absorbent includes agarose, etc., and the compounding amt. thereof is 5 to 50w/w%. The highly water- absorptive resin includes a starch system, etc. The pressure sensitive adhesive is prepd. by compounding 3 to 40w/w% rubber component, 5 to 50w/w% alicyclic satd. hydrocarbon resin and 3 to 40w/w% liquid rubber as its essential constituting components.
