Abstract
A coating is prepared by providing a plurality of metallic flake particles, depositing a surface-protective applied layer on the particle surfaces to form protected particles, and mixing the protected particles with a binder precursor to form a coating mixture. The coating mixture is applied to a substrate. The surface-protective applied layer is preferably silica, which is deposited by a sol-gel process from a tetraethyl orthosilicate solution.
