Patent ID: 8415016

Claim:
A hydrophobic substrate comprising a substrate and a hydrophobic treatment composition deposited on the substrate, wherein the hydrophobic treatment composition comprises (1) one or more compounds corresponding to the formula in which at least one R is a C a F 2a+1 group, a being an integer, optionally, another R is an SiX 3-b R 1 b group, b being 0, 1 or 2 X being at least one selected from the group consisting of a hydrolysable alkoxy, hydroxyl and halo group and R 1 being a lower alkyl group S is at least one selected from the group consisting of a hydrogen atom, an OH group, an alkyl group, and an OSiR 2 R 3 R 4 group, wherein R 2 , R 3 and R 4 are identical or different and selected from the group consisting of an SiX 3-b R 1 b group with b and X as defined above, a hydrogen atom, an alkyl group and an OSiR 2′ R 3′ R 4′ group with R 2′ , R 3′ and R 4′ being identical or different and selected from the group consisting of an SiX 3-b R 1 b group with b and X as defined above, a hydrogen atom and an alkyl group, n is an integer ≧1, wherein the total number of Si atoms does not exceed 20 and (2) a basic alcoholic solution.
