Abstract
A clear or colored top coating composition containing internally cross-linked microgel particles is disclosed. The microgel particles are produced by emulsion-polymerizing a monomer mixture of ethylenically unsaturated monomers including at least one cross-linking monomer and have a refraction index which is equal or close (.ltoreq.0.05) to that of a surrounding film-forming polymer fully cured with a cross-linking agent.
