    Abstract: 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.

    Abstract: 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.

    Abstract translation: 新的金属偶氮颜料包含a）至少两种式（I）的金属偶氮化合物或其互变异构形式的加合物，其中取代基具有说明书中所示的定义，和b）至少一种式 II）其中R6具有说明书中所示的定义，其特征在于在晶格常数为d = 10.3（±0.2）的X射线衍射图中，金属偶氮颜料具有强度为I1的信号S1， 从d = 16.05到d =11.78的晶格常数范围没有信号S2，其强度I2相对于信号S1的强度I1，以背景校正强度的比率I2 / I1表示，超过0.02， 特别适用于生产颜料制剂，尤其适用于生产滤色片。
