(57) [Summary] [Purpose] To obtain a coating liquid having a long pot life in the liquid and having excellent properties such as hardness, flexibility and stain resistance of the obtained coating film. [Structure] (a) Hydroxyl group-containing monomer 1 to 80 %, And (b) 20-99% by weight of another copolymerizable vinyl monomer, an acrylic polyol (A) obtained by copolymerization, an organosilicon compound represented by the following general formula (I), and / or the same. A coating liquid containing a partially hydrolyzed polycondensate and a hydrolyzate (B) to which water is added in an amount equal to or more than the amount required to theoretically hydrolyze 100%.
