Claim 15:
16. The coated substrate according to claim 1, wherein the coating forming composition is obtained by the process comprising:
a) chilling a mixture of alkoxysilane (i) and acid hydrolysis catalyst (iv);
b) adding metal oxide (ii) and water (vi) to the chilled mixture of step (a);
c) adding water-miscible solvent (iii) and additional acid hydrolysis catalyst (iv) to the mixture resulting from step (b);
d) aging the mixture resulting from step (c) under conditions of a temperature of 25 to 100° C. for a period of time of 30 minutes to 10 days_and providing a curable coating forming composition having a viscosity within the range of from about 3.0 to about 7.0 cStks at 25° C.; and,
e) optionally adding condensation catalyst (vi) at, during or following any of the preceding steps.
