We have researched the color properties of coordination compounds synthesized by us previously 
(8-(1′,2′-naphthyl)-1-R3-methyl-6-thiomethyl-4,5,7-triazaocta-1,3,5,7-tetraenato-1,1′-diolato(-)O, O′, N4, N7-M(II),
where R=CH3, C6H5, M=Ni, Co, Cu), which can be used for coloring thermoplastic masses. They meet the requirements
for use as a pigment for coloring thermoplastic masses . Colors of colored products have a high photostability (7
points), thermostability (>250 °C) and intensity of color that give a low consumption (0.004 to 0.008 g medium tone,
a 0.040-0.080 g to 100 g polystyrene intense tone and 0.002 to 0.008 g medium tone and 0.010-0.030 g intense tone
for 100 g polyethylene). Compounds of nickel (II) stained polystyrene and polyethylene in red, cobalt (II) - in green
with a yellow tinge, copper (II) - in deep red with a yellow tint.
