Abstract

Disclosed is a method for forming a water-repellent film on the surface of a transparent substrate (e.g., sheet glass). While the film on the coated substrate is dried, the temperature is controlled to fall between 15.degree. C. and 25.degree. C., the relative humidity is controlled to be 30% or preferably from 15% to 20%, and the speed of the air stream to be applied to the coated substrate is controlled to be 0.5 m/min or lower. The water-repellent film formed by the invention has a uniform thickness and good abrasion resistance.
