摘要 PCT No. PCT/EP98/00746 Sec. 371 Date Aug. 13, 1999 Sec. 102(e) Date Aug. 13, 1999 PCT Filed Feb. 11, 1998 PCT Pub. No. WO98/36030 PCT Pub. Date Aug. 20, 1998A colored pulverulent coating composition comprising spherical particles having a mean particle size >40 mu m, in two or more different color tints, where at least the particles of one color tint are colored and the particles of the other color tint may be colorless. The particles employed for the mixture each have a monomodal particle size distribution with a span (d90-d90/d50) of </=2.5. Furthermore the pulverulent coating composition can be melted at temperature <200 DEG C. to form a continuous coating, the differences in color which stem from the different-colored particles being indistinguishable to the human eye in the cured coating. The mean particle size (d50) of the spherical particles is preferably in the range from 40 mu m to >10 mu m. The novel coating composition can be used to produce coatings having a thickness of <50 mu m.
