More Information
Summary:The present invention relates to a fluorescent inkjet composition. The inkjet composition includes a fluorescent dispersion including a fluorescent colorant; wherein the inkjet composition emits light at a first intensity I1 in the range of 450 nm to 700 nm upon excitation by incident light having a wavelength in the range of 250 to 400 nm. In addition, the inkjet composition is capable of emitting light at a second intensity I2 upon exposure to a temperature of 60 ° C. for 8 weeks, wherein I2=(0.50 to 1.0)*I1.
