Wet and dry surface adhesives

A pressure sensitive adhesive comprising the polymerization product of a polymerizable composition comprising:

• (a) one or more (meth)acrylate ester monomers that when polymerized in the absence of other co-monomers yield a polymer or copolymer having a Tg of less than about 10° C.;
• (b) one or more hydrophilic non-acidic monomers selected from the group consisting of N,N-dimethyl acrylamide, N,N-diethyl acrylamide, tert-octyl acrylamide, N,N-dimethyl methacrylamide, N,N-diethyl methacrylamide, n-octyl acrylamide, and mixtures thereof, wherein the one or more (meth)acrylate ester monomers and the one or more hydrophilic non-acidic monomers are present in a ratio of about 1:1 to about 1.8:1;
• and
• (c) about 10 wt % to about 30 wt %, based on the total weight of polymerization product, of a reactive, ionic surfactant;
• wherein the pressure sensitive adhesive is solventless.
