Abstract
In the diazonium thermosensitive systems, phloroglucinol and phlorogrucide were investigated as black developing couplers. Black-like dye images could be obtained by using either of them and a basic compound as a catalyst. The color development occurs via the evolution of water of crystallization of couplers. Phloroglucide, which has lower solubility in water than phloroglucinol, showed better shelf-life characteristics.
