Abstract
The invention provides a water- and oil-repelling member having a primer layer as a first layer on at least one surface of a base material and further having a water- and oil-repelling layer as a second layer on the outer surface of the primer layer. The primer layer comprises a layer containing nano-diamonds and having a film thickness of 0.5 to 500 nm, the main component being an organic silicon compound having a plurality of silanol groups within a molecule. The water- and oil-repelling layer comprises a layer having a film thickness of 0.5 to 30 nm, the main component being a cured product of a hydrolysable fluorine-containing compound. The water- and oil-repelling member can stably and simply impart a water- and oil-repelling coat having excellent abrasion resistance to various base materials. In addition, the primer layer and the water- and oil-repelling layer can be coated even in a room-temperature (25° C.) process.
