摘要： The invention pertains to a process for producing a multilayer coat of enamel, wherein a pigmented base lacquer is applied, predried and overpainted with a clear powder and then base lacquer and clear powder layers are baked together. The invention is characterized in that the clear powder used has a particle size distribution in which a) at most 15 % by wt. of the clear powder particles have a particle size less than 10 νm, b) for at least 40 % by wt. of the clear powder particles the decimal logarithm of the quotient from the largest and smallest particles sizes is less than or equal to 0.25 and c) at least 98 % by wt. of the clear powder particles have a particle size less than 100 νm.
