The paper reports the results of QSPR analysis of several problems of coloration of textiles, including light fastness of azo benzothiazole and indigoid dyes, ionization of hydroxyl groups in mordant dyes forming complexes with polyvalent metal ions and rate reactions of organic substances with OH radical during catalytic oxidizing of pollutants. Multiple linear regression models are built with the use of fragment descriptors. The role of different molecular fragments is discussed emphasizing the mechanism of the phenomena and ways of application in coloration technology.
