The novel pigment preparations containing at least one metal azo pigment A) and at least one aliphatic monocarboxylic acid B) having 10 to 22 carbon atoms are suitable for the colouring of plastics and in this connection feature improved heat stability.

Pigment preparations

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 Ris hydrogen, halogen, COOH or COOR, Ris hydrogen, halogen, COOH, COORor CN, Ris alkyl or phenyl, Rand Rare each independently alkyl, R, R, R, Rand Rare each independently hydrogen, halogen, alkyl, alkoxy or COOR, and R, Rand Rare each independently alkyl.

Methine dyes

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.

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 which Ris hydrogen, halogen, alkyl, COOH or COOR, Ris oxygen or sulfur, Ris hydrogen, halogen, COOH, COORor CN, Ris alkyl or phenyl, Rand Rare each independently alkyl, Rand Rare each independently hydrogen, halogen, alkyl or COOR, and R, Rand Rare each independently alkyl.

Novel red methine dyes, methods for the preparation thereof, and use thereof for dyeing plastics, especially vinyl polymers, provide red colourings with improved colour strengths and improved colour brilliance.

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 colorings with improved light fastness and improved thermostability.

Yellow methine dyes

The novel yellow metal azo pigments based on at least two metal azo compounds which differ at least in the type of metal have both improved dispersion properties and improved color strengths and are of excellent suitability for pigmentation of pigment preparations for a broad field of use.

Metal azo pigments

The novel yellow metal azo pigments based on at least three metal azo compounds which differ at least in the type of metal have improved color strengths and are of excellent suitability for pigmentation of pigment preparations for a broad field of use.
