COATING MATERIALS FOR PROTECTING THE SURFACES OF TEETH

摘要

A coating material for protecting the surfaces of teeth is obtained by dissolving a resinous composition comprising 100 weight parts of a polystreyene resin or a high-impact polystyrene resin and 1 to 60 weight parts of rosin or a rosin derivative added thereto in an organic solvent. The resinous composition may further contain 1 to 100 weight parts of a chlorinated polymer and 1 to 100 weight parts of a coloring matter.
