摘要： A medical pressure-sensitive adhesive is provided, having a high steam permeability (at least 1100 g/(m.sup.2 .multidot.24 Hr) at a temperature of 37.degree. C. and an RH of 40%), and exhibiting such an appropriate adhesive strength as the dressing material coated with the pressure-sensitive adhesive is not easily peeled off and a wound is not inflicted on the skin when the dressing material is peeled from the skin, and also exhibiting durability of such an appropriate adhesive strength as well as an appropriate cohesive force. A medical pressure-sensitive adhesive, comprising a polymer containing above 50 wt % of a unit derived from an alkoxyalkyl acrylate, the Tg value of the homopolymer thereof being -35.degree. C. or less is also provided.
