| titleOfInvention | Neutral Hue Polymer Manufacturing Method |
| abstract | The present invention relates to a process for producing polymers that are neutral shades. A special feature of the present invention is that the a and b color values can be independently corrected in the Lab color space of the polymer. The above object can be achieved according to the method of the present invention for producing a polymer of neutral shade in one or more steps, wherein blue and / or red dyes are added to the process at a point before entering the final polymerization step, which is 3 ppm or less. The adjustment of the polymer neutral color tone, which is carried out with a blue dye in a dye mixture of at least 50% by weight and a total dye concentration in the polymer, preferably at most 2 ppm, particularly preferably at most 1 ppm, gives a and b color values in the Lab color space It occurs independently controlled and includes the following steps: Determining the a and b color values of the polymer without adding dyes; Determining the total dye concentration according to the desired b value shift; Determining the required red and blue mixture ratio according to the desired shift of a value; Treating the reaction mixture with a defined amount of dye mixture. |
