MEDICAL PRESSURE-SENSITIVE ADHESIVE COMPOSITION SUITABLE FOR APPLICATIONS SUCH AS MEDICAL PATCHES AND PATCH PREPARATIONS

摘要

PURPOSE: A medical pressure-sensitive adhesive composition is provided to suppress the denaturation caused by reaction with medical active components and to ensure excellent fixing property to the skin.;CONSTITUTION: A medical pressure-sensitive adhesive composition comprises an acrylic copolymer obtained by copolymerizing monomer components containing (a) at least one kind of a monomer of a (meth)acrylic acid alkyl ester and (b) at least one kind of a monomer of an N- hydroxyalkyl(meth)acrylamide, wherein a content of the (meth)acrylic acid alkyl ester monomer (a) with respect to a total amount of the monomer components is 50 weight% to 99.9 weight% and a content of the N- hydroxyalkyl(meth)acrylamide monomer (b) with respect to the total amount is 0.1 weight% to 20 weight%; and the monomer components are substantially free of a monomer having a carboxyl group.;COPYRIGHT KIPO 2011
