ABSTRACT:
A method for measuring the color difference between a sample dye and a standard dye by testing the color properties of both dyes, which comprises measuring the distribution curve of absorbance of individual components of the dye; determining the relationship between the color difference of dye solution and the color difference of dyeings with respect to the standard dye and representative samples arbitrarily selected plural lots of dyes; and predicting the color difference of dyeings from the color difference of solution between the standard dye and the sample dye.
