Provided is a coating composition having excellent long-term stability and exhibiting excellent transparency when formed into a coating film. The present invention is a coating composition which is characterized by containing a zirconium element-containing metal oxide (A) and a silane compound (B), and which is characterized in that the zeta potential value measured by the following method of the zirconium element-containing metal oxide (A) is 30 mV or more. < zeta potential determination method > using a laser Doppler electrophoresis method to determine 10% by mass of the aqueous dispersion of the zirconium-containing metal oxide (A) at room temperature (25 DEG C). 本发明提供经时稳定性优异且形成涂膜时发挥优异的透明性的涂覆用组合物。本发明为一种涂覆用组合物，其特征在于，其包含含锆元素的金属氧化物(A)和硅烷化合物(B)，该含锆元素的金属氧化物(A)的通过下述方法测定的zeta电位的值为30mV以上。＜zeta电位的测定方法＞利用激光多普勒电泳法在室温(25℃)下对10质量％的含锆元素的金属氧化物(A)水分散液进行测定。
