Abstract:
1. A resin solution composition consisting of: (A) a polyamic acid resin having the general formula (1): wherein X is a tetravalent organic radical containing 1 to 4 aromatic or aliphatic rings, Y is a divalent organic radical which comprises 10 to 50 mol % of a divalent organic radical having the structural formula (2): wherein R 1 is a divalent organic radical of 3 to 9 carbon atoms, R 2 and R 3 are each independently a substituted or unsubstituted monovalent hydrocarbon radical of 1 to 8 carbon atoms, and m is an integer of 1 to 99, and n is an integer of 5 to 300, (B) an alkoxysilyl-containing polyamic acid resin having the general formula (3): wherein X′ is a tetravalent organic radical, Y′ is a divalent organic radical, Z is a radical of the formula: R R the subscript a is an integer of 0 to 4, p is an integer of 1 to 300, q is an integer of 1 to 300, and r is an integer of 1 to 100, wherein the recurring units with the subscripts p and q are randomly arranged, and (C) at least one organic solvent selected from the group consisting of tetrahydrofuran, 1,4-dioxane, cyclopentanone, cyclohexanone, γ-butyrolactone, N-methylpyrrolidone N,N-dimethylacetamide, N,N-dimethylformamide, and dimethylsulfoxide.
