Statistics of the early synthetic dye industry: compiled data

This dataset is a compilation of information related to the early synthetic dye industry using 18 published documents: three editions of the Colour Index (CI), Schweppe’s list of synthetic dyes, Norton’s 1914 census, and annual census publications from the United States Tariff Commission (1918-1930). It includes the following fields: 1914 Schultz number Provided in census data prior to 1924 First edition CI number Determined from Schultz number in census data, using a conversion table in the 1st ed. CI Approximate date of introduction (CI, 1st ed) Number of manufacturers (CI, 1st ed) Chemical class (CI, 1st ed) CI constitution number Determined from 1st ed. CI #, and 2nd ed. CI conversion table CI generic name Determined from 1st ed. CI #, and 2nd ed. CI conversion table Lightfastness Tabulated from 3rd ed. CI for colourants listed in the 1st ed. CI Data selected for normal depth of shade, and direct dyeing without aftertreatment where applicable. See source document for details. Schweppe list Boolean indication of presence within the Schweppe list of early synthetic dyes US dye imports for the 1913-1914 fiscal year From Norton’s census of dyes imported in quantities above 10,000 lb. See source document for the list of dyes with undefined Schultz number, and the names of domestically produced dyes (quantities not reported). US dye imports for 1920: used as an example year (data not tabulated for other years due to relatively low quantities with respect to domestic production) US dye production for each year during the period 1917 – 1929 Quantities provided for most dyes on an annual basis; however, some values were withheld in the original documents to maintain manufacturer privacy. Dyes listed in significant quantities without Schultz/CI number (particularly sulphur dyes) were not tabulated here. See source documents for details.
