Patent ID: 8129467

Claim:
A curing accelerating compound-silica composite material obtained by subjecting at least one compound selected from compounds represented by the general formula (I-1) below and partial condensates thereof to a sol-gel reaction in the presence of a curing accelerating compound and water, R 1 n SiR 2 (4-n) (I-1) wherein n is 0 or 1, R 1 is selected from the group consisting of a hydrogen atom and a C1 to C18 substituted or unsubstituted hydrocarbon group, and is optionally bound to one or more R 2 s to form a ring structure, and R 2 s each represent a functional group reactive with a phenolic hydroxyl group, are selected independently from the group consisting of a halogen atom, a hydroxyl group, a C1 to C18 substituted or unsubstituted oxy group, a C0 to C18 substituted or unsubstituted amino group, and a C2 to C18 substituted or unsubstituted carbonyloxy group, the R 2 s are the same or are different from one another, and two or more R 2 s are optionally bound to each other to form a ring structure wherein the curing accelerating compound is at least one compound selected from compounds represented by the following formula (I-2) and intermolecular salts thereof, Wherein R 3 s are selected independently from the group consisting of a hydrogen atom and a C1 to C18 substituted or unsubstituted hydrocarbon group, the R 3 s are the same or are different from one another, and two or more R 3 s are optionally bound to each other to form a ring structure, R 4 s are selected independently from a hydrogen atom, a hydroxyl group, a C1 to C18 substituted or unsubstituted organic group, R 4 s are selected independently from a hydrogen atom, a hydroxyl group, a C1 to C18 substituted or unsubstituted organic group, the R 4 s are the same or are different from one another, and two or more R 4 s are optionally bound to each other to form a ring structure, and Y − is an organic group composed of a C1 to C18 organic group having one or more releasable protons, from which one proton was eliminated, and is optionally bound to one or more R 2 s to form a ring structure.
