Abstract
Abstract Orange colors having the anthrapyridine structure ##STR1## are disclosed wherein R 1 and R 2 are independently selected from among hydrogen, halos, lower alkyls, lower alkoxies, nitros, and sulfonates, R 3 and R 4 are independently selected from hydrogens, alkyls and alkylsulfonates of 1 through 3 carbon atoms and R 5 is a lower alkyl or lower alkyl sulfonate.
