Approximately 50% of positive results of dermal tests have been found to be induced by naphthol compounds added to dyes in the process of preliminary dying. Moreover, 2 cases of extensive hyperchromatism in persons concerned with the above mentioned textiles have been observed which, due to the treatment procedures and removed from work in exposure have partly subsided.
