Abstract: HOE 89/F 174 of the disclosure Coating material, process for the preparation of coatings and substrates coated therewith The invention relates to a coating material for the preparation of coatings, in particular multi-layer paint coatings composed of at least one base layer and, if appropriate, at least one transparent cover coat, the coating material containing film-forming resin (A), cellulose esters (B), solvents (C), metallic pigments (D) and, if appropriate, crosslinking agents (E) and also, if appropriate, further paint additives (F), wherein the cellulose ester (B) has an acetyl content of 2.0 to 30 % by weight, a butyryl content of 17 to 53 % by weight and an average molecular weight M? of at least 25,000, this cellulose ester (B) having been introduced into the coating material in the form of a pasty, thixotropic premix. The invention also relates to a process for the preparation of a multi-layer coating and to the substrates thus coated. The coating materials according to the invention are distinguished, inter alia, by high solids contents at low viscosities, and afford coatings with fault-free metallic effects.
