Process for treating metal surface
First Claim
1. A process for treating a metal surface comprising providing a liquid composition comprising an inorganic polymer produced by hydrolyzing and then polycondensing an organometallic compound having an organic functional group and a group capable of being hydrolyzed and then polycondensed in an organic solvent under conditions such that said organic functional group is kept unreacted and applying said liquid composition under conditions such that said inorganic polymer is adhered to the metal surface and said organic functional group is kept unreacted and remains on the metal surface.

Abstract
The present invention relates to a process for treating a metal surface wherein a liquid composition comprising an inorganic polymer is applied to the metal surface. The inorganic polymer is produced by hydrolyzing and then polycondensing, in an organic solvent, an organometallic compound having an organic functional group and a group capable of being hydrolyzed and then polycondensed in an organic solvent.
According to the present invention, the metal surface per se is made chemically reactive by fixing functional groups on the metal surface an is very useful, for example, as a support for making a presensitized lithographic plate.
