COATING LIQUID FOR FORMING TRANSPARENT FILM, METHOD FOR PRODUCING COATING LIQUID FOR FORMING TRANSPARENT FILM, BASE MATERIAL WITH TRANSPARENT FILM AND METHOD FOR PRODUCING BASE MATERIAL WITH TRANSPARENT FILM

摘要

PROBLEM TO BE SOLVED: To provide a coating liquid for forming a transparent film that hardly causes cracks after coating the base material.SOLUTION: The coating material for forming a transparent film is produced by dissolving or dispersing (A) an organic compound capable of forming a chelate with a metal alkoxide, (B) at least either one of a hexafunctional silane compound represented by the general formula (2) as given below and a hydrolyzed condensate thereof and (C) at least either one of a metal alkoxide represented by the general formula (3) as given below and a hydrolyzed condensate thereof in a mixed solvent including an organic solvent. The molar ratio (M1)/(M3) of the mol number (M1) of the component (A) to the mol number (M3) of the component (C) is in the range of not less than 0.25 to less than 2 and the molar ratio (M2)/(M3) of the mol number (M2) of the component (B) to the mol number (M3) of the component (C) is in the range of not less than 0.5 to not more than 8. (the general formulae (2) and (3) are as described in the specification.)SELECTED DRAWING: None
