The invention relates to a method for multi-layered coating of substrates, whereby a colour and/or effect giving base enamel coating agent is applied to a substrate which has been optionally pre-coated with a ground coating agent and/or filler coating agent and/or other coating agents, whereupon a varnish coating is subsequently applied to the colour and/or effect giving base enamel coating. According to the inventive method, the colour and/or effect giving base enamel coating agent contains bonding agents which harden by means of radical and/or cationic polymerisation under the effect of high-power radiation.
L'invention concerne un procédé de préparation d'un laquage multicouche, selon lequel un agent de recouvrement de vernis de base conférant la couleur et/ou à effet est appliqué sur un substrat éventuellement recouvert au préalable d'un agent de recouvrement d'apprêt et/ou d'un agent de recouvrement de charge et/ou d'autres agents de recouvrement. Une couche de vernis clair est ensuite appliquée sur la couche de vernis de base conférant la couleur et/ou à effet. Selon ce procédé, l'agent de recouvrement de vernis de base qui confère la couleur et/ou est à effet, utilisé, contient des liants durcissant sous l'effet de rayonnements de haute énergie, par polymérisation radicalaire et/ou cationique.
