Zusammenfassung:	The present disclosure is to provide a surface treatment composition that may impart excellent corrosion resistance, blackening resistance, and alkali resistance, and an intrinsic surface color property to a ternary hot-dip galvannealed steel sheet. The present disclosure provides a surface treatment composition containing: based on 100 wt% of a solid content of the composition, 70 to 90 wt% of a resin mixture including a high molecular weight polysilicon-modified polyurethane main resin, a low molecular weight polysilicon-modified polyurethane auxiliary resin, and an acrylic urethane auxiliary resin; 5 to 25 wt% of a melamine-based curing agent; 0.5 to 10 wt% of an inorganic additive; 0.5 to 10 wt% of a silane coupling agent; 0.1 to 2 wt% of an adhesion promoter; 0.1 to 2 wt% of a coloring pigment; and 0.1 to 1 wt% of a pigment stabilizer.
