PCT No. PCT/EP94/02011 Sec. 371 Date Feb. 12, 1996 Sec. 102(e) Date Feb. 12, 1996 PCT Filed Jun. 20, 1994 PCT Pub. No. WO95/02010 PCT Pub. Date Jan. 19, 1995The invention relates to a process for spray-painting with aqueous paints, in which paints with different colors are processed, recovered paint is recycled, if desired after admixing with newly supplied paint (fresh paint), to the coating operation, and (a) the substrates are selected such that some of the substrates can painted using a mixture of the paints with different colors ("mixed paint"), and (b) the substrates are selected such that the proportion of the paints with different colors in the overall amount of paint processed is from 10 to 90% by weight, and (c) the substrates are selected such that the proportion in which the paints with different colors are processed corresponds to the proportional content of the paints with different colors in the mixed paint, and/or (d) care is taken, by selecting the color of the fresh paint which is admixed, to ensure that the recovered paint has the same color as the mixed paint.
