<p>PROBLEM TO BE SOLVED: To obtain the subject composition excellent in storage stability, capable of forming a cured coating film having a combination of good flatness, hardness, transparency, heat resistance and adhesiveness to substrates and useful for e.g. a protective coat of liquid crystal display materials by including a specified alkoxysilane (condensate) and an epoxy resin. SOLUTION: This composition contains (A) an alkoxysilane (condensate) having >=1 amic acid linkage in the molecule such as a compound obtained by reacting an aminoorganoalkoxysilane such as an multivalent aminoorganoalkoxysilane with an acid anhydride such as trimellitic acid anhydride and (B) an epoxy resin such as a multifunctional epoxy resin. The mixing ratio of A/B is preferably 0.7-3.0 based on the active group equivalent of the component A per epoxy equivalent of the component B. It is preferable to make color filters by using coating films formed from the composition.</p> |
