The present application relates to a method for the controlled and/or slow release of a biologically active hydroxyl group containing substance on a substrate which comprises reacting said hydroxyl group containing substance subsequently with a halogen-substituted aliphatic carboxylic acid halide and either a diamine containing at least one tertiary amino group or a heterocyclic aromatic amine, applying the thus obtained water-soluble ester to the substrate and finally hydrolysing the ester on the substrate.
