Patent ID: 6858257

Claim:
A powder coating composition comprising composite powder particles that are an agglomerate of individual particulate components fused or bonded together, wherein the size distribution of the agglomerate of particles is up to a maximum of 120 μm with a Dv.50 within the range of from 15 to 75 μm, wherein the individual particulate components comprise (1) two or more colored base components having a Dv.99 of no more that 30 μm, wherein at least one of the colored base components is per se non-film-forming and comprises one or more coloring agents dispersed in a carrier, and (2) one or more uncolored film-forming components, wherein at least one of the uncolored film-forming components is an uncolored film-forming component (2a) and (i) has a Dv.99 that is more than 20 μm and (ii) has a higher Dv.99 than the Dv.99 of the two or more colored base components (1) taken together or has a higher Dv.50 than the Dv.50 of the two or more colored base components (1) taken together, wherein, the ratio of colored base components to the one or more uncolored film-forming components in the powder coating composition is from 1:99 to 60:40 by weight.
