Abstract
Procedure for the preparation of acridonibos dyes, characterized in that carboxydiphenylamines of the formula are reacted **(See formula)** in which n means a positive integer, preferably 1; one of the symbols X signifies a nitro, cyano or sulfonamidic group, while the other symbol X signifies a nitro group or a hydrogen atom; a Y means a hydrogen atom, while the other Y means a hydrogen or halogen atom or a sulphonamide group, in addition to that one of the symbols Y e X (preferably X) represents a sulphonamide group that is linked to the acridonic framework by its -SC2 bridge, with ring sealing agents; O well by reacting sulfonic acids of the formula **(See formula)** in which n has the same meaning attributed to it in the explanation of the first formula; a X'means a nitro, cyano or sulfonic acid group, while the other X' means a nitro group or a hydrogen atom; a Y'means a hydrogen atom, while the other Y' means a hydrogen or halogen atom or a group of sulfonic acid; and one of the symbols Y'and X' (preferably X') represents a SO3H group that is linked to the acridonic framework by its -SO2 bridge, with sulfohalogenating agents and ring locks and amidate the obtained acridonic sulfohalides.
