Claims
- 1. The compound of the formula ##STR3##
- 2. The .beta.-form of the compound according to claim 1 having the formula ##STR4## said .beta.-form being characterized by giving orange pigmentations in polyvinyl chloride which do not change color on heating to 180.degree. C. for 30 minutes and by having an X-ray diffraction spectrum (CuK.sub..alpha. radiation) exhibiting lines at d-values of 9.0, 8.25, 7.40, 5.60, 4.60, 4.35, 3.86, 3.76, 3.68, 3.56, 3.26, 2.80 and 2.65 .ANG..
- 3. A polymeric material containing, as a pigmenting agent, the .beta.-form of the compound of the formula ##STR5## said .beta.-form being characterized by giving orange pigmentations in polyvinyl chloride which do not change color on heating to 180.degree. C. for 30 minutes and by having an X-ray diffraction spectrum (CuK.sub..alpha. radiation) exhibiting lines at d-values of 9.0, 8.25, 7.40, 5.60, 4.60, 4.35, 3.86, 3.76, 3.68, 3.56, 3.26, 2.80 and 2.65 .ANG.., said pigmenting agent being present in an amount sufficient to impart the desired shade to the polymeric material.
- 4. A polymeric material according to claim 3, said polymeric material being viscose, cellulose acetate, polyethylene, polystyrene or polyvinyl chloride.
