Abstract
A surface-treated substrate consisting essentially of a substrate having at least two treated surface layers wherein the first layer constituting the outermost layer among the treated surface layers is a layer obtained by treatment with a compound (I) capable of forming a surface having a contact angle of at least 70.degree. against water and the second layer constituting an underlayer in contact with the outermost layer is a layer obtained by treatment with at least one reactive silane compound (II) selected from the group consisting of isocyanate silane compounds and hydrolyzable silane compounds.

A surface-treated substrate consisting essentially of a substrate having at least two different treated surface layers wherein the first layer constituting the outermost layer among the treated surface layers is a layer obtained by treatment with a compound (I) containing at least one Si--NCO group capable of forming a surface having a contact angle of at least 70.degree. against water, and the second layer constituting an underlayer in contact with the outermost layer is a layer obtained by treatment with at least one reactive silane compound (II) selected from the group consisting of isocyanate silane compounds and hydrolyzable silane compounds.
A surface-treated substrate having a treated surface layer formed by treatment with an isocyanate silane compound having at least one polyfluoroorganic group.
