ABSTRACT:
A fluorescent article includes an underlayer colored fluorescent film and an overlayer colored fluorescent film, which is provided over the underlayer colored fluorescent film. The underlayer colored fluorescent film includes a first fluorescent colorant in an underlayer polymer matrix. The overlayer colored fluorescent film includes a second fluorescent colorant in an overlayer polymer matrix. The second fluorescent colorant in the overlayer film at least partially blocks light in a first wavelength range while allowing transmission of an amount of light in a second wavelength range effective to make the first fluorescent colorant fluoresce.
