An object of the present invention is to provide a coating composition with which it is possible to make coated paper that is excellent in various properties such as glossiness, water resistance, solvent resistance, heat resistance, thermal blocking resistance and ink penetration and that can readily be recycled. This object of the invention can be attained by a coating composition comprising a hydrosol emulsion and colloidal silica, wherein the hydrosol emulsion is obtained by neutralizing, with an alkali, a synthetic resin emulsion prepared by dispersing, in water, particles of a synthetic resin having carboxyl group and an alkoxysilyl group. |
