Patent ID: 7556860

Claim:
A laminate, comprising: a first silica-based film; a second silica-based film on the first silica-based film; and an organic film on the second silica-based film; and wherein the second silica-based film includes an organic group containing a carbon-carbon double bond or a carbon-carbon triple bond; and wherein the second silica-based film is a film obtained by forming a coating by using a film-forming composition which includes a hydrolysis-condensation product obtained by hydrolysis and condensation of the following silane compound (A) and the following silane compound (B) in the presence of an acidic, basic, or metal chelate compound, and curing the resulting coating, wherein the concentration of the total amount of the compound (A) and the compound (B) at the time of hydrolysis and condensation is 0.1 to 30 wt %; (A) at least one silane compound selected from the group consisting of compounds shown by the following general formula (1), compounds shown by the following general formula (2), and compounds 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 an organic group, R 1 represents an organic group, and a represents an integer of 1 or 2, Si(OR 2 ) 4 (2) wherein R 2 represents an 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 to R 6 individually represent organic groups, b and c individually represent integers from 0 to 2, R 7 represents an oxygen atom, a phenylene group, or a group —(CH 2 ) m —, wherein m represents an integer from 1 to 6, and d represents 0 or 1; and (B) at least one silane compound selected from the group consisting of compounds shown by the following general formula (4) and compounds shown by the following general formula (5), wherein R x represents an organic group containing a carbon-carbon double bond or a carbon-carbon triple bond, and R 81 to R 83 individually represent a hydrogen atom, a halogen atom, a hydroxyl group, an alkoxyl group, or an organic group, provided that at least one of R 81 to R 83 represents an atom or a group other than the organic group, wherein R y represents a divalent organic group containing a carbon-carbon double bond or a carbon-carbon triple bond, and R 91 to R 96 individually represent a hydrogen atom, a halogen atom, a hydroxyl group, an alkoxyl group, or an organic group, provided that at least one of R 91 to R 93 and at least one of R 94 to R 96 represent an atom or a group other than the organic group, wherein the organic film includes at least one compound selected from a polyarylene, polyarylene ether, polybenzoxazole, and polyimide.
