<p>The disclosure relates to a self-healing enamel having a solvent and a coating material, where a substance for the self-healing is dispersed in the enamel, preferably a polyurethane based enamel, whose chemical composition corresponds to a pre-stage of the coating material, where this pre-stage can be converted spontaneously into the material of the coating material in the event of exposure, wherein the substance for the self-healing forms cores of sheathed particles, where the particle sheaths comprise an in-air oxidizable substance, and wherein a photoactivatable or a thermoactivatable catalytic material such as titanium oxide, zinc oxide or indium zinc oxide is stored in the particle cores, which in the event of activation supports the oxidation of the oxidizable substance of the particle sheaths, where in the case of the photoactivatable catalytic material, the substance for the self-healing and the oxidizable substance is transparent for electromagnetic irradiation of the excitation wavelengths of the photoactivatable material.</p> |
