Abstract:

PROBLEM TO BE SOLVED: To obtain an acrylic self-adhesive compsn. for medical use which well sticks to the skin, hardly causes a pain in the skin or keratin separation when peeled from the skin, does not leave behind a self-adhesive, has a high moisture permeability, and hardly causes the stagnation of perspiration by compounding an acrylic copolymer with a cross-linker.
SOLUTION: This compsn. is prepd. by compounding 100 pts.wt. acrylic copolymer with 0.01-5 pts.wt. at least difunctional isocyanate cross-linker (a polyisocyanate compd.) and if necessary other additives and percutaneously absorbable drugs. The acrylic copolymer used is produced by copolymerizing 50-97wt.% 4-12C alkyl (meth)acrylate, 2-49wt.% alkoxypolyalkylene glycol ester of acrylic acid represented by the formula (R1 and R2 are each H or methyl; R3 is 1-20C alkyl; and n is 2-12), 1-15wt.% hydroxyl monomer, and and 0-30wt.% other copolymerizable monomers.
