Abstract

PURPOSE: To make a surface smoothness of a obtained magnetic layer superior by heating previously the water-emulsion system magnetic paint, which is applied onto a substrate, from the substrate side immediately before drying with heat.
CONSTITUTION: After the substrate where a water-emulsion system magnetic paint is applied has the substrate surface, which is opposite to the face where the magnetic paint is applied, heated previously to 60 to 120°C by a heating means such as a heat roll and an infrared-ray heater, the magnetic paint is dried with heat. As a result, defects such as a large output fluctuation and inferiority in other various kinds of electromagnetic conversion characteristic can be cancelled.
