Abstract: Coating compsn. contains (A) a film-forming resin, (B) a cellulose ester, (C) solvent, (D) metal pigment and opt. (E) crosslinkers and (F) further lacquer additives and of the type esp. to give a multi-layer coating with a base layer and opt. a clear topcoat. (i) the cellulose ester (B) has an acetyl content of 2-30 (pref. 2-5) wt.%, a butyryl content of 17-53 (pref. 47-53) wt.% and an average mol.wt. of at least 25000, pref. 30000-60000; and (ii) this cellulose ester is introduced into the coating compsn. in the form of a pasty, thixotropic pre-mix (e.g. with the crosslinkers). The solids content of the compsn. is pref. 15-30 wt.%. The cellulose ester pre-mix pref. contains a diluent which swells the cellulose ester, esp. an aromatic or aliphatic hydrocarbon or a higher alcohol. alcohol.

Abstract: Preparation of heat-curable, water-dilutable coating compositions based on (A) epoxy resins free from amino groups, (B) an aqueous dispersion or solution of saturated polyester resins or the modification products thereof with oils, (C) organic cross-linking agents and optionally (D) pigments and/or conventional adjuvants, in specific proportions, these components being processed together in one or more stages, while being comminuted from their original particle size, to form a homogeneous coating composition which has a particle size of less than 100 mu m, and the use of the coating compositions thus obtained as coating agents, particularly for coating metal substrates, by the use of current-free methods of application or electrostatic spraying.

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.
