Abstract

PURPOSE: To prepare a novel clear plaster which does not cause allergy to the skin, by using a polyurethane film as the substrate and a specific synthetic copolymer as the basis of the plaster in place of raw rubber.
CONSTITUTION: An organic solvent solution of a composition composed of (A) 40W60wt% natural rubber or synthetic isoprene rubber, (B) 10W30wt% olefin polymers such as low density polyethylene, and (C) 20W40wt% triisocyanate, is applied to a polyurethane film, and dried to obtain a primer layer. Separately, a homogeneous mixture is prepared by compounding a plaster basis composed of a styrene/isoprene/styrene block copolymer, etc., a mixture containing a modifier composed of a low density polyethylene, etc., and a drug basis (e.g. glycol salicylate). The homogeneous mixture is spread over the above prepared primer layer to afford the objective clear plaster. The contamination of the drug basis with the impurities (e.g. proteins) in the raw rubber can be prevented in the present plaster.
