A substrate having an antifriction dry coating film that reduces friction or blocking on a substrate surface, obtained by removing water content from an aqueous coating film-forming composition, and the dry coating film has a structure that is overcoated on a silicone rubber surface; wherein the aqueous coating film-forming composition comprises: one or more types of solid lubricants selected from mica, talc, kaolinite, sericite, and chlorite; a thickener containing as a clay mineral one or more types selected from saponites, bentonites, and montmorillonites, having viscosity thickening properties where the viscosity of a 2 wt% aqueous dispersion of one or more types of thickeners selected from water-soluble organic polymers and clay minerals that is at least 1000 mPa-s; wherein water-soluble organic polymers are components which can be modified by mixing with the clay mineral to form a hydrophilic composite with the clay mineral; and a silicone binder in the form of an oil-in-water silicone emulsion containing: 100 parts by mass of a polyorganosiloxane having at least two hydroxyl groups or hydrolyzable groups bonded to a silicon atom in one molecule, where the viscosity at 25°C is within a range of 100,000 mPa-s to 20,000,000 mPa-s; 5 to 120 parts by mass of colloidal silica (as calculated by solid fractions); 1 to 100 parts by mass of an ionic emulsifier selected from anionic surfactant, cationic surfactant, or amphoteric surfactant;
