Abstract
Provided is a method for forming a coating containing an organic acid in a glass sheet production line while controlling an increase in the haze ratio of the glass. The method of the present invention is a method for producing a coated glass sheet, the method including the steps of cutting a glass ribbon to form a plurality of glass sheets in a glass sheet production line; and applying a solution onto the glass ribbon or the plurality of glass sheets in the glass sheet production line, the solution containing an organic acid and at least one selected from a water-soluble polymer and a polyphosphoric acid salt. The water-soluble polymer is preferably a water-soluble high-molecular-weight polymer, and more preferably a water-soluble copolymer. A preferred water-soluble copolymer contains a vinylpyrrolidone unit.
