Articles having a coating of the colored powder composition are also provided.
First claim
Opening claim text (preview).
What is claimed is: 1. A composition, comprising: a base powder particle having a median particle size of at least 25 microns; and a weakly associated layer on the base powder particle, wherein the weakly associated layer consists of 4,500 to 9,000 non-incorporated white pigment particles and a plurality of non-incorporated colored pigment particles. 2. The composition of claim 1 , wherein the base powder comprises up to 25 wt. % incorporated white pigment, based on the total weight of the base powder. 3. An article, comprising: a substrate having a coating deposited thereon, wherein the coating is a coalesced powder coating that prior to coalescence comprises a base powder particle having a median particle size of at least 25 microns; and a weakly associated layer about the base powder particle that consists of 4,500 to 9,000 non-incorporated white pigment particles and a plurality of non-incorporated colored pigment particles. 4. The composition of claim 3 , wherein the base powder particle comprises up to 25 wt % incorporated white pigment, based on the total weight of the base powder.
