Abstract
The kinetics of the photoyellowing of silk in the presence of a sulpho nated benzotriazole UV absorber has been investigated. A power kinetic equation describing surface reactions on an energetically and exponen tially inhomogeneous surface has been used for that purpose. A correla tion between yellowness index and carbonyl group formation during irra diation is shown. (C) 1998 Elsevier Science Limited. All rights reserv ed.
