The invention relates to an aqueous medium containing an amino(meth)acrylate polymer or copolymer which is not soluble in demineralised water, characterized in that the medium has a content of an aqueous phase of at least 60% by weight and a content of up to 40% by weight of solids comprising the amino(meth)acrylate polymer or copolymer, whereby the aqueous phase is charged by a sufficient amount of carbon dioxide that effects the amino(meth)acrylate polymer or copolymer to be present in solute form in the medium. The aqueous medium may be used beneficially as a coating or binding solution for the spray coating or binding of pharmaceutical compositions or nutraceutical compositions or cosmetical compositions.
