摘要：The light fading rate of magenta dye, 4-aza-(p-diethyl-aminophenyl)-pheny1-3-methyl-pyrazole-5-one, was studied. The dye was prepared by the method of coupling development, and extracted from the reaction product. Then, it was dispersed into a cellulose acetate film.According with spectral fading of the dye, absorptions of 270 nm and 540 nm contributed to the fading reaction each other, but 440 nm did not.The kinetic expression of fading rate for 540 nm light was as follows.-dC/dt= (K/C₀)ΔI·CK: rate constant C_o: initial concentration of the dyeI: absorbed light C: concentration of the dye
