摘要：

Condensation of 3-cyano-4-methyl-6-hydroxyl-1-[3'-methoxypropyl]-2- pyridone 2 with nitroso- and formyl-substituted N,N-dialkylalylamines in ethanol at room temperature in the absence of catalyst afforded dyes giving from magenta io 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.
