Patent ID: 7462678

Claim:
A process for producing a film forming composition comprising hydrolyzing and condensing: (A) at least one silane compound selected from a compound (A-1) shown by the following general formula (1), a compound (A-2) shown by the following general formula (2), and a compound (A-3) shown by the following general formula (3), R a Si(OR 1 ) 4-a (1) wherein R represents a hydrogen atom, a fluorine atom, or a monovalent organic group, R 1 represents a monovalent organic group, and a represents 1 or 2; Si(OR 2 ) 4 (2) wherein R 2 represents a monovalent organic group; R 3 b (R 4 O) .3-b Si—(R 7 ) d —Si(OR 5 ) 3-c R 6 c (3) wherein R 3 , R 4 , R 5 , and R 6 individually represent a monovalent organic group, b and c individually represent an integer of 0 to 2, R 7 represents an oxygen atom, a phenylene group, or a group —(CH 2 ) m — (wherein m represents an integer of 1 to 6), and d represents 0 or 1; and (B) a cyclic silane compound shown by the following general formula (4) wherein X and Y individually represent a hydrogen atom, an alkyl group, aryl group, allyl group, or a glycidyl group, and n represents an integer of 2 to 8, wherein the hydrolysis and condensation are carried out in the presence of (C-1) a metal chelate compound shown by the following general formula (5): R 8 e M(OR 9 ) f-e (5) wherein R 8 represents a chelating agent, M represents a metal atom, R 9 represents an alkyl group having 2 to 5 carbon atoms or an aryl group having 6 to 20 carbon atoms, f represents the valence of the metal M, and e represents an integer of 1 to f, wherein the concentration of the component (A) and the component (B) at the time of the hydrolysis and condensation is 1 to 30 wt % converted into complete hydrolysis-condensation product.
