Abstract Process for coating metal strip in the coil coating process using coating materials based on polyester imide resins The invention relates to a process for coating metal strip in the coil coating process. The coating materials employed consist of: a) 3 to 50% by weight, preferably 20 to 40% by weight, of polyester imide resins, the 20 to 60% by weight solu- tions of which possess viscosities from 90 to 4,000 mPas at 23°C and the hydroxyl values of which are in the region from 50 to 300, b) 3 to 40% by weight, preferably 10 to 30% by weight, of pigments and/or fillers, c) up to 3% by weight of suitable auxiliary substances and additives and d) 10 to 90% by weight, preferably 20 to 60% by weight, of one or more organic solvents, the sum of a), b), c) and d) being 100% by weight. The invention further relates to the use of the metal strip produced by the process according to the invention for production of exhaust components.
