Abstract
Concerning colour fastness to light the following aspects were noted : 1- there is no great in light fastness due to variations in the diazonium component used, although considerable difference in the degree of light fastness was observed among the dyes on different fibres, nylon-6 being the worst. 2- Dyes 10, 11, 12, 13, have a remarkable colour fastness to light, specially on polyester and triacetate fibres.
