Energy transfer between fluorescent organic pigments (fluorophors) dispersed in a paint vehicle was studied for mixtures of a yellow, a red, and an orange fluorescent pigment, and for mixtures of these with titanium dioxide. Radiative energy transfer occurs among the fluorophors, but not between them and titanium dioxide A shift to longer wavelengths of the emission peak of a fluorophor with increasing paint‐film thickness was noted and was ascribed to reabsorption and reemission of fluoresced radiation within the overlapping excitation and emission region typical of these organic fluorophors.
