ABSTRACT:
A process for making solid colored particles by preparing a reaction solution in water comprising formaldehyde, urea, a cyclic polyamine functional triazine compound, and acid. A dye can be incorporated into the reaction solution if a color other than white is desired. Particles are formed having an average particle size between 1 and 70 microns without the need to resort to crushing to break up agglomerates. Particles made by this process provide excellent color and are easily washable from a substrate when incorporated into a washable formulation.
Additionally, it has been found that the incorporation of colored microcapsules of average size of 1-70 microns where the color is located primarily on or in the shell of the microcapsule also provides excellent washable compositions when incorporated into a washable formulation.
