Does not include derivatives of carbazole (Colour Index Nos. 948, 969). 3 Includes drug and cosmetic colors, external, data on which cannot be published separately without disclosing information received in confidence. Does not include acetate rayon dyes that appear under "Dyes grouped by prototype number." 9 Does not include azoic dyes and their components that appear under "Dyes grouped by Colour Index number" and "Dyes grouped by prototype number." The production and sales of dyes grouped by Colour Index number showed the greatest decreases in 1957. Production of Colour Index dyes was 99 million pounds in 1957, compared with 109 million pounds in 1956--representing a decline of 9.0 percent. Sales of Colour Index dyes totaled 88 million pounds, valued at 85 million dollars, in 1957, compared with 112 million pounds, valued at 99 million dollars, in 1956--representing a decrease of 21.3 percent in quantity and 14.0 percent in value. On the other hand, the output of prototype dyes in 1957 was 29 million pounds, or 4.4 percent more than the 28 million pounds produced in 1956. Sales of these dyes in 1957 totaled 25 million pounds, valued at 44 million dollars, compared with 28 million pounds, valued at 51 million dollars, in 1956. Production of ungrouped dyes totaled 15 million pounds, in both 1956 and 1957. Sales of these dyes, however, amounted to 13 million pounds, valued at 35 million dollars, in 1957, compared with 15 million pounds, valued at 36 million dollars, in 1956. Among the individual dyes for which statistics are given in this report, decreases in production were reported for many important low- and medium-priced dyes. The output of synthetic indigo in 1957 was 8.1 million pounds, or 13.9 percent less than the 9.4 million pounds reported in 1956; that of direct black EW (C.I. dye 581) was 5.2 million pounds, or 4.5 percent less than the 5.4 million pounds reported in 1956. Decreased output in 1957, compared with 1956, was reported also for algol yellow GC (Pr. dye 9), which showed a decline of 36.8 percent; orange II (C.I. dye 151), a decline of 29.7 percent; anthraquinone vat jade green (C.I. dye 1101), a decline of 28.3 percent; anthraquinone vat brown R (C.I. dye 1151), a decline of 21.5 percent; methyl violet blue B and base (C.I. dye 680), a decline of 20.6 percent; and anthraquinone vat olive R (C.I. dye 1150), a decline of 12.5 percent. On the other hand, production of a number of important dyes increased in 1957, although sales of some of these dyes were smaller than in 1956. Increased output in 1957, compared with 1956, was reported for chrome blue black R (C.I. dye 202), which showed an increase of 108. 2 percent; indanthrene brown BR (Pr. dye 118), an increase of 39.2 percent; anthraquinone vat green B and black B (C.I. dye 1102), an increase of 37.3 percent; chrome black T (C.I. dye 203), an increase of 31.4 percent; anthraquinone vat brown G (C.I. dye 1152), an increase of 27.0 percent; indanthrene olive T (Pr. dye 547), an increase of 16.7 percent; and direct fast scarlet (C.I. dye 326), an increase of 16.1 percent. Table 9 shows production and sales of dyes in 1957, by chemical class. Four chemical classes of dyes accounted for 76.5 percent of the total quantity of all dyes produced: azo dyes accounted for 35.4 percent of the total; anthraquinone vat dyes, for 18.5 percent; sulfur dyes, for 15.7 percent; and indigoid and thioindigoid dyes, for 6.9 percent. The output of all these classes of dyes was smaller in 1957 than in 1956. Production of sulfur dyes declined 30.3 percent in 1957 compared with 1956; indigoid and thioindigoid dyes, 20.9 percent; anthraquinone vat dyes, 8.3 percent; and azo dyes, 0.7 percent. Table 10 shows the average annual production of dyes in the 5 years 1951-55, together with annual data for 1956 and 1957, by class of application. Table 11 gives corresponding data for sales. TABLE 9.--Synthetic organic chemicals: United States production and sales of coal-tar dyes, by chemical class, 1957 3 Includes azine, oxazine, phthalocyanine, pyrazolone, sulfur dyes not included in Colour Index group, thiazine, and miscellaneous dyes, and sales of thiazole dyes. Statistics for these groups cannot be published separately without disclosing information received in confidence.
