Oberflächenbehandeltes Substrat und Verfahren zu seiner Herstellung

摘要

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 formed by treating with a treating agent containing a compound (I) capable of forming a surface having a contact angle of at least 70 DEG against water, and the second layer constituting an underlayer in contact with the outermost layer is a thin film layer of a heat resistant polymer formed by treating with a treating agent containing a compound (II) capable of forming a thin film of a heat resistant polymer and fine particles of a polymer, to form a thin film and heating the thin film to thermally decompose the fine particles of a polymer.
