    摘要： The present invention relates to novel methine dyes, methods for the preparation thereof and use thereof for dyeing plastics, especially polyamides, so as to obtain yellow to orange colourings with improved light fastness and improved thermal stability. Such dyes include a dye of the formula (I) in which
    R1 is hydrogen, halogen, COOH or COOR11, R2 is hydrogen, halogen, COOH, COOR12 or CN, R3 is alkyl or phenyl, R4 and R5 are each independently alkyl, R6, R7, R8, R9 and R19 are each independently hydrogen, halogen, alkyl, alkoxy or COOR13, and R11, R12 and R13 are each independently alkyl.

    摘要： The new metal azo pigments comprising the adduct of a) at least two metal azo compounds of the formula (I) or their tautomeric forms in which the substituents have the definition indicated in the description, and b) at least one compound of the formula (II) in which R6 has the definition indicated in the description, are characterized in that in the X-ray diffractogram with a lattice constant of d=10.3 (±0.2) Å the metal azo pigment has a signal S1 with an intensity I1 and in the lattice constant range from d=16.05 Å to d=11.78 Å has no signal S2 whose intensity I2 in relation to the intensity I1 of signal S1, expressed as ratio I2/I1 of the background-corrected intensities, exceeds a value of 0.02, and are outstandingly suitable for producing pigment preparations and especially for producing color filters.

    摘要： The present invention relates to novel methine dyes, methods for the preparation thereof and use thereof for dyeing plastics, especially polyamides, so as to obtain yellow to orange colourings with improved light fastness and improved thermal stability. Methine dyes for example accord to the formula (I) in whichR1 is hydrogen, halogen, alkyl, COOH or COOR9,R2 is oxygen or sulfur,R3 is hydrogen, halogen, COOH, COOR10 or CN,R4 is alkyl or phenyl,R5 and R6 are each independently alkyl,R7 and R8 are each independently hydrogen, halogen, alkyl or COOR11, andR9, R10 and R11 are each independently alkyl.
