In this study, self-colored polyurethane based on naphthalimide (N) and anthraquinone (A) dyes was investigated as point of thermal and fluorescent behaviors. The self-colored waterborne polyurethane (WPU) has characterized by using a different instrument such as thermogravimetric analysis (TGA), differential thermogravimetric (DTG), FTIR, UV-vis spectroscopy, and fluorescent spectrophotometry. Generally, these self-colored polymers were obtained by reacting dye with prepolymer during the reaction.
