Abstract
A material is impregnated into leather by incorporating the material into micro-capsules and then applying the micro-capsules to the leather material by means of a suitable process. A roller coating process is described in which the material is applied to a roller under which the leather material passes whilst compressed. Alternatively, the micro-capsules may be applied to the leather by drumming-in in a wet process.
