Document Type and Number:
Japanese Patent JP6605129
Kind Code:
B2
Abstract:
The present invention relates to a composition for surface-treating a single-side-plated steel sheet, to a surface-treated steel sheet using the same composition, and to a method for surface-treatment using the same composition. More specifically, the surface-treatment composition comprises: an acrylic-urethane copolymer resin (A); a Si-Zr-Ti based organic-inorganic hybrid additive (B); and a solvent, and satisfies the following formulae 1 and 2. [Formula 1] 0.3 < [A]/([A]+[B]) < 0.7 [Formula 2] 20 wt.% < [A] + [B] < 70 wt.% (In formulae 1 and 2 above, [A] and [B] respectively signify the content (wt.%) of A above and the content (wt.%) of B above, with respect to the total amount (100 wt.%) of the surface-treatment composition)
