The present invention provides a hydrolyzable silyl group-containing (meth)acrylic copolymer obtained by copolymerizing a silane compound having alkyl(meth)acrylate, a hydrolyzable functional group, and a radical polymerization unsaturated group, a coating composition including an organometallic catalyst and having low-temperature curability, alkali resistance, solvent resistance, adhesion, and also a cured product including the same. According to the present invention, even when a silane content is increased for improving hardness of a coating film, and the composition is applied on a base material, the composition becomes a material maintaining alkali resistance, and having good adhesion, solvent resistance and a low-temperature curing property. Despite cured at a low temperature without using isocyanate, the composition has excellent stability and no risk of toxicity due to the isocyanate.
