(57) [Summary] [Structure] A coating composition for forming a silica film, which comprises a modified polysilazane obtained by reacting one or more polysilazanes having at least a specific repeating unit with a phenol compound, And a coated substrate having a silica-based coating formed using the coating composition. [Effect] By drying and baking the coating film obtained by coating the above coating composition on a substrate, a coated substrate in which the irregularities of the coated surface are highly flattened can be obtained. |
