WATER-REPELLENT TREATED SUBSTRATE AND PRODUCTION METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide: a water-repellent treated substrate that does not impair the quality texture of the substrate even while possessing the high water-repellency as well as that can realize the water-repellency with a small amount of water-repellent; and a production method thereof.SOLUTION: Provided is a water-repellent treated substrate production method including a step for forming an interlayer onto a substrate, and a step of forming a water-repellent layer onto said interlayer, and which is characterized in that the interlayer is composed of organosilicon-based material and the water-repellent layer is composed of fluorine-based compound. The substrate obtained by said production method has a water contact angle of 130° or more.
