PROBLEM TO BE SOLVED: To obtain a thermosetting resin solution composition having excellent storage stability by using a polynadimidesiloxane precursor resin prepared by reacting nadic anhydride or the like with an aminoorganoalkoxysilane or the like. SOLUTION: An aminoorganoalkoxysilane (e.g. γ- aminopropylmethyldiethoxysilane) represented by the formula: R<1> n Si(OR<2> )4-n [wherein R<1> is an aminoalkyl, an N-alkylaminoalkyl, an aminoaryl or the like; R<2> is H, an alkyl, an aryl or the like; and n is 1-3] or a hydrolyzate thereof is dissolved in a solvent (e.g. 3-methyl-3-methoxybutanol) having a boiling point of about 100-300 deg.C. Next, an equimolar amount of nadic anhydride or an alkylnadic anhydride is added to the solution under agitation and reacted for about 0.5-2hr at about 5-150 deg.C to obtain a thermosetting resin solution composition containing a polynadimidesiloxane precursor. A coating fluid prepared from this composition is applied to a glass plate, dried by heating, and cured to obtain a color filter. |
