Claim 17:
18. The coated substrate according to claim 1, wherein the coating forming composition is obtained by the process comprising:
a) chilling a mixture of the metal oxide (ii) and the acid hydrolysis catalyst (iv) to a temperature of about −10° C. to about 10° C.,
b) to the chilled mixture of step (a), adding the alkoxysilane (i) to the chilled mixture of step (b);
c) allowing the mixture obtained in step (b) to come to room temperature of about 25° C.,
d) adding the at least one water miscible organic solvent (iii), and optionally the condensation catalyst (vi) and optionally one or more other optional components (vii) to the mixture obtained in step (c) to obtain a composition having a viscosity within the range of from about 3.0 to about 7.0 cStks at 25° C.
