U.S. production and sales of organic pigments during the period of 1983 to 1992 ate tabulated in Table 8. More detailed information by color class is provided from 1988 to 1992 in Table 9. In addition, information about export, import, and apparent domestic consumption of organic pigments appears in Tables 10 and 11. 

Statistics for the production of basic dyes include those products hsted as cationic dyes, eg, cyanines, for dyeing polyacrylonitrile fibers and the classical triaryhnethane dyes, eg, malachite green, for coloring paper and other office apphcations (2,53). Moreover, statistics for triaryhnethane dyes are also hidden in the production figures for acid, solvent, mordant, and food dyes, and also organic pigments. Between 1975 and 1984, the aimual production of basic dyes in the United States varied from 5000—7700 t. However, from 1985—1990, aimual production of basic dyes varied from 5000—5700 t, and the annual sales value increased from 56 to 73 million per year.
