    摘要: To obtain a water-resistant polarizing film free from deterioration in dichroic ratio caused by water-resistant treatment, it is critical that adjacent sulfonic acid groups or sulfonate groups in the organic dyes to be used for the polarizing film are spaced at moderate intervals. In a process for producing a water-resistant polarizing film of the present invention, the polarizing film before water-resistant treatment includes an organic dye which comprises an azo compound 20 represented by the following general formula (2)

    摘要: The invention relates to a pigment composition based on P.Y. 191 of the formula (1) containing 0.05 to 30 mol %, based on the sum of P.Y. 191 and a further yellow colorant, of at least one further yellow colorant of the formula (2) and/or of C.I. Pigment Yellow 100 in which R1, R2, R3 and R4 are each independently hydrogen, halogen, —CH3, —NO2, or NH—R6 where R6 is C1-C4-alkyl; R5 is methyl or carboxyl, and where the compound of the formula (2) is not C.I. Pigment Yellow 191.
