A wet-stick pressure-sensitive adhesive is provided wherein the pressure- sensitive adhesive comprises: at least one copolymerized monoethylenically unsaturated (meth)acrylic acid ester monomer, wherein the (meth)acrylic acid ester monomer, when homopolymerized, has a Tg of less than about 10 °C; at least one copolymerized hydrophilic acidic comonomer; and at least one nonreactive copolymer comprising at least two copolymerized alkylene oxides, at least one of which is hydrophobic and at least one of which is hydrophilic.

L'invention concerne un adhésif sensible à la pression, collant aux surfaces humides, comprenant : au moins un monomère d'ester d'acide (méth)acrylique copolymérisé, insaturé en monoéthylène, lequel, lorsqu'il est homopolymérisé, présente une Tg de moins d'environ 10 DEG C ; au moins un comonomère acide hydrophile copolymérisé ; et au moins un copolymère non-réactif comprenant au moins deux oxydes d'alkylène copolymérisés, dont au moins un est hydrophobe et au moins un est hydrophile.
