Abstract
PURPOSE: To obtain attain improvements in hardness and scratch resistance, soil resistance, and solvent resistance by coating a light-curable transparent paint on the primer or intermediate layer printed with color crossing lines and then curing it upon irradiation with light.
CONSTITUTION: The surface of a cold rolled, galvanized or a zinc alloy plating base steel sheet is processed by primary and/or intermediate coating. Specified color lines are printed on a cold rolling, galvanized or zinc alloy plating a base steel sheet. The thickness of the color lines printed layer should be less than 50 μm because the printed layer thicker than 50 μm may not be dried easily to reduce the printing efficiency. Light-curable transparent paint is coated on the printed board and exposed to light to cure the paint. The thickness of dried and hardened paint is recommended in the range of 1-200 μm. The thinner than 1 μm has not sufficient protecting performance for the printed lines and the thicker than 200 μm becomes easily to obtain cracks since it shrinks a lot during the curing.
