PURPOSE: To improve the preservability and the printing characteristics by forming a thin concealing layer having excellent whiteness and concealability. CONSTITUTION: A concealing layer 10 is formed of aluminum paste in which non-leafing type aluminum powder and leafing type aluminum pieces are mixed, the concealability is enhanced by the powder and skin whiteness is improved by the pieces. The layer 10 contains binder in which nitrocellulose and acrylic resin are mixed, and since the both have solvent resistance, the bleedout of dispersant, coupling agent, etc., included in the magnetic powder of the layer 4 and the paste of the layer 10 can be prevented. A recording medium having excellent preservability is obtained and the adhesive properties of the layer 12 can be improved by the acrylic resin. |
