SUBSTRATE PROVIDED WITH WATER-AND-OIL REPELLENT LAYER, AND METHOD FOR PRODUCING SUBSTRATE WITH WATER-AND-OIL REPELLENT LAYER

摘要

Provided are a substrate provided with a water-and-oil-repellent layer having excellent abrasion resistance and a method for producing a substrate provided with a water-and-oil-repellent layer.　A substrate provided with a water-and-oil-repellent layer having a substrate, an underlayer formed on the surface of the substrate, and a water-and-oil-repellent layer formed on the surface of the underlayer, in which the underlayer contains an oxide that contains silicon and a specific element, and the water-and-oil-repellent layer comprises a hydrolytic condensate of a fluorine-containing ether compound selected from the group consisting of compounds represented by formula (A1) and compounds represented by formula (A2). Formula (A1): Rf-O-(Rf1O)m-Rf2[-R1-C(-R2-T)a(-R3)3-a]b Formula (A2): [(T-R2-)a(R3-)3-aC-R1-]bRf2-O-(Rf1O)m-Rf2[-R1-C(-R2-T)a(-R3)3-a]b
