摘要： Clear lacquer coating media suitable for multi-layer coatings, containing self-crosslinking or externally crosslinkable binder vehicles, organic solvents, and in the case of externally-crosslinkable binder vehicles containing one or more crosslinking agents which are different from aldehyde condensation resins, and optionally also containing one or more reactive thinners and customary additives for clear lacquers, with an additional content of A) 0.1 to 3% by weight one or more urea compounds, and B) 0.05 to 10% by weight one or more substances which supply formaldehyde, with respect in each case to the resin solids content which is formed by the binder vehicles, reactive thinners and crosslinking agents.

摘要： A process for lacquer coating substrates with a colored and/or effect base lacquer and a clear lacquer topcoat, in which a colored and/or effect base lacquer layer of a base lacquer coating composition is applied onto a substrate and is provided in a wet-on-wet process with a clear lacquer coating. Before being jointly stoved or jointly cured with the base lacquer layer, the uncured clear lacquer layer is exposed to high-energy radiation. In the clear lacquer coating composition, the resin solids content contains 50 to 98 wt. % of a system A) thermally curable by addition and/or condensation reactions, which system contains substantially no free-radically polymerisable double bonds and substantially no groups capable of reacting in another way with free-radically polymerisable double bonds of a system B). The resin solids content further contains 2 to 50 wt. % of a system B) which is curable under the action of high-energy radiation by free-radical polymerisation of olefinic double bonds, wherein the weight percentages adds up to 100 wt. % and the C═C equivalent weight of the total resin solids content of A) and B) is between 300 and 10000. Clear lacquer coating compositions made by the process are also described.
