Abstract

Process for the preparation of optical brighteners of the stybic series, characterized by copying the diazonic compound of a 4-amino-3'-halogen-stilbene-2-sulphonic acid with 2-aminonaphthalene sulphonated, or sulphonated in position 1, and oxidizing the obtained o-aminoazoic dye, to form a compound of the formula I ** (See formula) ** wherein X means halogen up to atomic number 17, inclusive.
