Abstract

Process for the preparation of 7-triazinyl-amino-3-phenylcoumarins, characterized in that in a 2,4,6-trihalogeno-1,3,5-triazine, conveniently in inert solution or suspension organic or organicoacuous, or in the dough In the case of a melt and in the presence of acid fixatives, a halogen atom with a 7-amino-3-phenylcoumarin in which the phenyl radical can be subsequently substituted in a non-ionogenic manner, and a subsequent halogen atom with a base of inorganic or organic nitrogen containing substitutable hydrogen at a basic nitrogen atom, and because it is optionally substituted in the obtained condensation product, also the third halogen atom with alkali by hydroxyl-, with alkali- oxoxide-, -phoxide, - Alkylmercaptide or -phenylmercaptide by ether groups, or with an inorganic or organic nitrogen base with substitutable hydrogen at a basic nitrogen atom by an amino radical, so that condensation products of general formula I are formed ** (See formula) ** where they mean R1 and R2 each hydrogen or aliphatic, araliphatic, hydroaromatic, aromatic-isocyclic, hydrogenated heterocyclic and aromatic-heterocyclic hydrogenated radicals, and R1 and R2 together with the nitrogen atom, furthermore, still saturated heterocyclic radicals, R3 a substituted phenyl radical, optionally non-ionogenic, and X halogen, hydroxyl, an ethereal or amino radical of formula ** (See formula) ** in which R'1 and R'2 each mean hydrogen, or one of the substituents defined under R1 and R2, to which effect the components are selected in such a way that in the final product there are no substituent contents that present an acid reaction, nor that they form salts, nor that they produce a dye character.
