Transdermal patch having a pressure-sensitive adhesive comprising (meth)acrylic acid alkyl ester, N-hydroxyalkyl(meth)acrylamide, and vinyl monomers |
摘要 |
The patch according to an embodiment of the present invention includes: a support; and a pressure-sensitive adhesive layer on at least one surface of the support, wherein: the pressure-sensitive adhesive layer contains 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; a content of the (meth)acrylic acid alkyl ester monomer (a) with respect to a total amount of the monomer components is 50 wt % to 90 wt % and a content of the N-hydroxyalkyl(meth)acrylamide monomer (b) with respect to the total amount is 1 wt % to 20 wt %; and the monomer components are substantially free of a monomer having a carboxyl group. |
