Color intensity control in polymers using triarylmethane leuconitriles as color formers
Several triarylmethane leuconitriles have been synthesized. Color formation rates of triarylmethane dyes from corresponding leuconitriles have been compared in various media. Routes to color-on-demand processes are discussed.
