The effect of certain new cellulose‐reactive ultraviolet absorbers on the stability of cotton cellulose to light is described. Exposure to the radiation of fading lamps and to sunlight at various sites has shown that the absorbers provide protection from light, but that the effect is not sufficiently long‐lived in tropical climates. The mechanism of degradation of cotton in very hot climates appears to differ from that in more temperate regions. The accelerated phototendering of cotton caused by certain colourless rotproofing agents can be decreased by using these absorbers, but the phototendering produced by vat dyes is not greatly affected.
