Data on the synthesis of 19 new azo-pyrazoles which are promising for use as dyes for polycaproamide are reported. Their structure and the properties of the polycaproamide fabrics dyed with them were investigated and a correlation was established between the structure of the azo-pyrazoles and the color fastness of the fabrics in laundering, wet and dry rubbing, and exposure to light and molds.
