FIELD: road engineering. SUBSTANCE: discrete portions of reflective coating are covered with polymer selected from group consisting of polyalkylacrylates, polyalkylmetacrylates, polyesters, vinyl polyesters, vinyl polymers, polyurethanes, cellulose esters, fluorocarbon polymers, polycarbonates, polyolefins, polyvinylacebales, ionomeric copolymers and ethylene or propylene copolymers with methacrylic acid or vinyl acetate. Visible image is formed on polymer by powdered toner, which contains dye, transparent polymeric binder adhering to polymer of above mentioned discrete portions of coating and charge carrier. Charge carrier contains polymer selected from group consisting of methacrynic polymers with functional groups having at least amino quaternary ammonia groups and azine dyes. EFFECT: increased efficiency and enhanced reliability in operation. 4 dwg
