The invention relates to a highly scratch-resistant multilayer coat on an optionally primed substrate, comprising the following layers which are superimposed on one another in the following sequence (A) a base coat layer (B) a first clear lacquer layer as an intermediate layer and (C) a second clear lacquer layer as the top layer. The multilayer coat is characterised in that the second clear lacquer layer (C) can be produced from a coating material (C) which contains (C1) at least one oligomer and/or polymer, comprising at least one lateral carbamate group and/or allophanate group (c11), in particular, comprising a carbamate group (C11) of the formula: -O- (CO)-NH2; -O-(CO)-NH-(CO)-NH2 and (C2) at least one cross-linking agent which contains at least 2 functional groups (c21) that undergo cross-linking reactions with the carbamate group and/or allophanate group (c11). The invention also relates to a method for producing highly scratch-resistant multilayer coats.

L'invention concerne un laquage multicouche hautement résistant aux rayures, réalisé sur un substrat éventuellement pourvu d'une couche de fond, par superposition, dans cet ordre, de: (A) une couche de laque de base; (B) une première couche de laque transparente, servant de couche intermédiaire; et (C) une seconde couche de laque transparente, constituant la couche supérieure. Ce laquage multicouche se caractérise en ce que la seconde couche de laque transparente (C) peut être réalisée à partir d'une matière de recouvrement (C) qui contient: (C1) au moins un oligomère et/ou polymère comportant au moins un groupe carbamate et/ou un groupe allophanate (c11) latéraux, en particulier un groupe carbamate (C11), correspondant aux formules: -O-(CO)-NH¿2? et -O-(CO)-NH-(CO)-NH¿2?, et (C2) au moins un agent de réticulation contenant au moins deux groupes fonctionnels (c21) qui entrent en réaction de réticulation avec le groupe carbamate et/ou le groupe allophanate (c11). L'invention concerne également un procédé de réalisation de laquages multicouches hautement résistants aux rayures.
