Stability and Degradation Issues of Manganese Violet Pigment in Polymeric Paints: Morphological and Chemical Changes Under SO<sub>2</sub> and Humidity Exposure

This study focuses on investigating the stability of modern and contemporary paints based on manganese violet pigment PV16 (NH<sub>4</sub>MnP<sub>2</sub>O<sub>7</sub>) when exposed to atmospheric pollutants, specifically sulfur dioxide (SO<sub>2</sub>) in the presence of high relative humidity. In p...
