Description 361-368
Two new bifunctional reactive fluorescent whiting agents based on joining two coumarin moieties together through
triazinyle-stilbene fluorescent moiety have been successfully synthesized, applied on nylon-6 fabrics and then characterized by
NMR and elemental analysis. Spectral properties, such as absorption and emission spectra in solution and on fabrics are
investigated. The application of all the prepared compounds as fluorescence [fluorescence whiting agents (FWAs)] and their
whiteness as well as light fastness properties on nylon-6 fabric have been compared with monofunctional agent. Despite the fact
that the FWAs, containing either mono or bis methyl coumarin derivatives, show better whiteness properties than the FWA
containing phenyl coumarin derivative, the later compound shows higher light fastness (excellent).
