Abstract
Abstract Condensation of 3-cyano-4-methyl-6-hydroxyl-1-[3′-methoxypropyl]-2-pyridone 2 with nitroso- and formyl-substituted N , N -dialkylarylamines in ethanol at room temperature in the absence of catalyst afforded dyes giving from magenta to cyan colouration of cellulose acetate film. The visible absorption properties of the dyes were studied in different solvents and their thermal and photochemical stabilities assessed.
