PURPOSE: A roll mold coating method for a prism sheet is provided to prevent crystalline particles from becoming fine by continuously supplementing an additive. CONSTITUTION: A roll mold coating method for a prism sheet is as follows. A plating solution is prepared using nickel sulfate 300-350 g/L, boric acid 35-60 g/L, nickel chloride 3-10 g/L, sodium lauryl sulfate 0.1-0.3g/L, and additive(S110). A plating work is performed in the plating solution with less than 3A/dm2 current density, 55-60°C temperature, and pH 3-4.
