ABSTRACT:
A solid substrate, which contains or consists of a biologically or chemically active substance, is coated with coating material containing at least one polymerizable crosslinkable polyfunctional acrylic or methacrylic compound whereafter the coating material is subjected to polymerization substantially in the absence of non-polymerizable components to form a network coating of polymer on the surface of the solid substrate. This coating permits either the controlled release of active substance from the coated substrate or the controlled access of material reacting with said active substance into the coated substrate and the controlled release of the resulting reaction products from the coated substrate.
