Compositions are provided which contain (a) one or more polysiloxanes
comprising at least one reactive functional group; a plurality of
particles; and optionally, one or more curing agents comprising at least
one functional group that is reactive with any reactive functional group
of polysiloxane (a). Additionally, a process for applying the
multi-component composite coatings described above to a substrate and
coated substrates are provided. A process for preparing the coating
compositions also is provided. The multi-component composite coating
compositions of the invention provide highly scratch resistant
color-plus-clearcoatings capable of retaining scratch resistance after
weathering.
