Substrate having treated surface layers and process for producing it

摘要

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 formed by covering with a composition (I) containing a predetermined organic silicon compound, and the second layer constituting an underlayer in contact with the first layer is a layer formed by covering with a composition (II) containing a fluorine-containing reactive silane compound (II) which forms a surface having a contact angle of at least 100° to water.
