Beschreibung
Zusammenfassung:	The present invention relates to a substrate (1) coated with a porous coating (2), to the processes for manufacturing the coating, and to its applications. The porous coating (2) is essentially mineral and of the sol-gel type, having a series of closed pores with at least the smallest characteristic dimension being, on average, equal to or greater than 20 nm but less than or equal to 100 nm.
