ABSTRACT:
The present invention provides a medical adhesive and a medical adhesive tape or sheet superior in the fixing performance, particularly perspiration-resistant fixing, which shows low skin irritation and suitable adhesive strength. The present invention provides a medical adhesive containing a water-dispersed copolymer obtained by copolymerizing 100 parts by weight of a monomer mixture containing (meth)acrylic acid alkyl ester and 0.005-2 parts by weight of a silane monomer copolymerizable with the ester, and an organic liquid component compatible with the copolymer; a medical adhesive containing a water-dispersed copolymer obtained by copolymerizing a monomer mixture containing (meth)acrylic acid alkyl ester and a silane monomer copolymerizable with the ester, and an organic liquid component compatible with the copolymer, wherein the gel fraction after crosslinking of the copolymer is 40-80 wt %, and the weight average molecular weight of a sol component after crosslinking is not less than 300000; and a medical adhesive tape or sheet having the medical adhesive at least on one surface of a support.
