The present invention relates to a composition containing silico-organic nanohybrid and/or microhybrid capsules for scratch-resistant and/or abrasion-resistant coatings, wherein the silico-organic nanohybrid and/or microhybrid system includes one or more small metal oxide cores A and a substantially complete, silico-organic shell B, and the composition can be obtained by a reaction performed in situ, in a synthetic resin or in a synthetic-resin precursor compound, between metal oxide particles (KA—O) and at least one organofunctional silicon compound which contains an organofunctional group and at least one hydrolyzable group or at least one hydroxy group. The present invention also relates to the use of such compositions as the base for lacquers for producing a scratch-resistant and abrasion-resistant coating on a substrate as well as articles provided with corresponding scratch-resistant as well as abrasion-resistant coatings.
