Hj. Verhey et al., CROSS-LINKING AND DRYING OF A 2-COMPONENT WATERBORNE COATING MONITORED BY A FUNCTIONALIZED CHARGE-TRANSFER FLUORESCENCE PROBE, Polymer, 38(17), 1997, pp. 4491-4497
A donor-bridge-acceptor fluorophore with extreme sensitivity to enviro
nmental influences has been attached covalently to a polyamino crossli
nker. It was found that the progress of the crosslinking reaction with
an aceto-acetate functionalized polyacrylate dispersion can be monito
red from the fluorescence wavelength shift of the fluorophore. Also fo
rmation and drying of films applied from the resulting labelled disper
sion induces a significant wavelength shift of the fluorescence of the
incorporated label. (C) 1997 Elsevier Science Ltd.
