The present invention is directed to a composition and method of providing a silicone release coating material for a thermally-responsive record material while maintaining strong printability with UV inks and water based inks, as well as scuff resistance. The thermally-responsive record material includes a substrate with first and second surfaces. The first surface includes a heat sensitive coating having a colorless dye precursor and an acidic developer material in contiguous relationship. The release coating is provided with an aqueous mixture of a water soluble or water dispersible polymeric material, a silicone release agent, an excess of platinum catalyst, and a hydrophilic silica. The platinum catalyst is preferably provided in excess of 150 ppm. The hydrophilic silica is preferably fumed silica. The release coating is cured at a temperature of 160&#xb0; C. or less, or even from 70&#xb0; C. to 120&#xb0; C.
