| Abstract: | The effect of a number of halogenophenyl esters of 4-carboxymethoxy-2-hydroxybenzophenone on the stability of cotton cellulose to light and soil burial is described. These compounds possess ultraviolet-absorbing as well as rotproofing properties, and give leach-resistant finishes on cotton that resist soil burial better than pentachlorophenyl laurate and do not accelerate photochemical tendering. Exposures at an urban site in England and at hot-wet and hot-dry sites in Australia show that they exercise a moderate protective effect against light and weather for a limited time at the first two sites but the effect is very small at the third. |
