Author(s): K. A. Ahmed, D. M. Masoud, H. M. Ahmed and Mervat El-Sedik

Fluorescent dyes are important colored compounds used for different application one of them is textile coloration. The scientific literature includes fluorescent dyes studies for different purposes. This work aims to synthesize new fluorescent dyes based on chromeno[2,3-d]pyrimidin-4-one moiety , studying their photophysical properties and their ability to print polyester and polyamide fabrics. The printed fabrics with new fluorescent chromeno-pyrimidin- 4-0ne dyes have high light fastness, excellent perspiration, washing and rubbing. The fluorescence quantum yield of the prepared dyes lie in the range from 0.10 to 0.90.
