とである。In recent years, there has been an increasing demand for the printing appearance of metal cans, and there has been a demand for better printing finish than ever. The design of metal cans can be divided into two types: one in which white paint is applied to the entire can wall and printing, and the other in metallic printing based on gold and silver, utilizing the metallic luster unique to metal cans. With regard to the former, it is necessary to develop a plated steel sheet that can obtain a high degree of whiteness after can-making, and as to the latter, it is necessary to develop a plated steel sheet that can obtain a metallic luster after the can-making. Therefore, an object of the present invention is to provide a plated steel sheet having excellent film adhesion after processing and excellent printed appearance.
