Abstract

In this research, disperse yellow 232 was synthesized, purified and subjected to spectroradiometric study in different resin media. Alkyd, maleic and phenolic resins as common useful resins in offset printing inks were applied to study the effects of different media on fluorescent emission of the dye. Reflectance curves in two UV-cut and UV-add statuses were measured under A light source. The emissions in the different media were calculated in two different ways. First, calculation of emission intensities differences in UV-cut and UV-add reflection curves in maximum emission wavelength, and second, calculations of difference area between the two curves were measured, and the results were in good accordance.
