Application 10/047,024
2) Nogami teaches that R1 may be a 3-glycidoxypropyl group.
Col. 3, l. 17.
3) Nogami teaches that the aluminum salt is used to improve
hardness of the film. Col. 3, ll. 28-29.
4) Nogami teaches that the deposition inhibitor prevents
crystallization of the aluminum salt on the surface of the film
during drying. The deposition inhibitor may be N-methyl-
pyrrolidone. Col. 3, ll. 40-44.
5) Nogami states that the deposition inhibitor is used in an
amount at least equal in weight proportion to the aluminum salt in
terms of Al2O3. Col. 3, ll. 45-47.
6) Nogami teaches that the catalyst used for hydrolysis of the
tetraalkoxysilane of formula (1) must be basic. Col. 3, ll. 55-56.
7) According to Nogami, the hydrolyzed solution obtained by
hydrolyzing the tetraalkoxysilane of formula (1) forms silica
particles as the hydrolyzed product. Col. 4, ll. 21-25.
8) According to Nogami, the hydrolysis of the alkoxysilane of
(2) is conducted in the presence of an acid catalyst and an
aluminum salt. Nogami, col. 4, ll. 29-33.
9) Nogami discloses that:
The tetraalkoxy titanium of formula (3) to be
employed in the present invention may be added to the
alkoxysilane of formula (2) during its hydrolysis. Apart
from this, however, addition of the hydrolyzed solution
of the alkoxysilane of formula (2) to a solution of the
tetraalkoxy titanium in an organic solvent is preferred to
obtain a liquid coating composition having excellent
storage stability. The hydrolyzed solution of the
