Abstract : A process for conveniently producing microcapsules containing a gelatin wall crosslinked with quinone and a core of an active compound such as a fouling reducing agent, particularly a tributyl tin chloride, involves use of a simple or complex coacervation technique. The quinone crosslinking provides microcapsules of excellent strength, storage stability, and resistance to aqueous exposure, such that the rate of release of the fouling reducing agent can be controlled with precision. jg
