L'invention concerne des matériaux pour vitrage comprenant un substrat revêtu d'un revêtement fonctionnel et d'une couche de protection organique permanente déposée sur au moins une partie du revêtement fonctionnel. La couche de protection organique est obtenue par réticulation d'une composition polymérisable comprenant : a) des composés (méth)acrylates ne comprenant pas de groupe polyorganosiloxane, b) au moins un composé comprenant un groupe polyorganosiloxane et au moins deux fonctions (méth)acrylates et c) éventuellement un amorceur de polymérisation. The invention relates to glazing materials comprising a substrate coated with a functional coating and a permanent organic protective layer deposited on at least part of the functional coating. The organic protective layer is obtained by crosslinking a polymerisable composition comprising: a) (meth)acrylate compounds that do not include a polyorganosiloxane group; b) at least one compound that includes a polyorganosiloxane group and at least two (meth)acrylate functions; and c) optionally a polymerisation initiator.
