Two crystals of triazine derivatives, 2,4-diamino-6-benzyl-1,3,5-triazine (1) and 2,4-diamino-6-(4′-methylbenzyl)-1,3,5-triazine (2), are synthesised by a direct reaction of cyanoguanidine with the respective cyanocompounds. The IR spectra of the compounds are very similar. In the crystals the molecules are interconnected by N{single bond}H?N hydrogen bonds forming one-dimensional hydrogen bonded polymer in 1 and three-dimensional hydrogen bonded network in 2. The arrangement of molecules in the crystal of 1 is denser than in 2 due to the π-π interactions between the π-clouds of the aromatic triazine rings that are absent in the crystal of 2. The geometries of the molecules in the crystals have been compared with those obtained by ab-initio molecular orbital calculated results that represent the geometries of molecules in the gas-phase.
Colorant compositions and processes

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.
