| It is disclosed that aryl azo pyrazolones may be used as colorants in electroscopic toners. |
| Ardrox, a mixture of alkyl aryl polyglycol ethers, alkylalcohol ethoxylate propoxylate, and petroleum distillates, provides a yellow color. |
| This reaction should take place in darkroom conditions to protect the aryl azide from photolysis. |
| Amines are also classified as aliphatic, having only aliphatic groups attached, or aromatic, having one or more aryl groups attached. |
| An alkyl group is a straight chain molecule, but if the modifier is in the form of a ring structure it is more properly called an aryl group. |
| The compounds are furans, thiophenes and pyrroles substituted by two aryl groups and an aliphatic acid group containing from two to six carbon atoms or a derivative thereof. |
