Abstract
The invention relates to a dispersion suitable for use as coating agent and binder for pharmaceutical forms, having a solids content of 10–70% by weight consisting of a) from 90 to 99% by weight of a methacrylate copolymer consisting of at least 90% by weight of (meth)acrylate monomers containing neutral radicals and having a glass transition temperature Tg of from −20° C. to +20° C. as determined by the DSC method, and b) 1–10% by weight of a nonionic emulsifier having an HLB of from 15.2 to 17.3.
