Substrate, at least part of at least one of the faces of which has a geometry which is optionally obtained by means of a coating and which differs from that of an ideal uniform, perfectly plane or even slightly curved, sheet, in that it has a bumps-and-hollows relief which can be defined by submicron sizes which, almost in their entirety, fall into at least two different classes, the respective representative values of which vary by a factor of at least 5 or of at most 1/5; applications of this substrate to anti-stain and anti-mist or anti-rain glazing; processes for preparing the substrate.
