HIGHLY FUNCTIONAL NEW FLUORESCENT DYES EXCELLENT IN DURABILITY AND SOLUBILITY AND METHOD FOR PRODUCING SAME

摘要

The present invention relates to a novel fluorescent dye having high functionality and excellent solubility and a method for producing the same. Specifically, the present invention relates to a novel fluorescent dye compound having a stilbene-based sulfone symmetric structure using anilinesulfonic acid, a method for producing the fluorescent dye compound, a composition comprising the fluorescent dye compound, and a fluorescent brightening method using the same. The novel fluorescent dyes synthesized in the present invention have both a high dyeability, a solubility and an excellent fluorescent whitening effect which could not be exhibited in conventional fluorescent dyes. Therefore, it can be usefully used for paper, fiber or plastic products, and further it can reduce the environmental pollution problem caused by dyes that are not dyed because of the high salt rate of the dyed materials, so that they can be used as environmentally friendly fluorescent dyes.;COPYRIGHT KIPO 2019
