Abstract
Procedimiento en vistas a la fabricación de colorantes de la fórmula general **(Ver fórmula)** en la que: n es 1 ó 2 en la que: Y y Z forman junto con los dos átomos de carbono contigüos ciclos pentagonales o hexagonales en la que: los dos átomos de la cadena polimetínica son ciclados por un puente exterior componiéndose al menos de dos átomos de carbono o de nitrógeno o de los dos juntos mientras que los otros pueden ser substituídos o no caracterizado por el hecho de que las combinaciones de la fórmula general designadas como "productos intermediarios" **(Ver fórmula)** o respectivamente: **(Ver fórmula)** en la que: n es 1 ó 2 en la que: Z con los dos átomos de carbono cercanos forma un ciclo pentagonal o hexagonal en la que: dos átomos de carbono de la cadena abierta son ciclados por un puente compuesto al menos de dos átomos de carbono o de nitrógeno o al menos de un átomo de carbono y al menos de un átomo de nitrógeno y en la cual V es = O =N-arilo o -(O-alcoilo)2 W es -Oh ONa -O-alcoílo -O-CO-alcoílo -O-CO-arilo o un grupo de aminas substituído o halógeno son condensados en proporciones moleculares con combinaciones carbo-o heterocíclicas de 5 ó 6 átomos que contienen un grupo metilo reaccionante inmediato a un grupo CO.Procedure for the manufacture of dyes of the general formula ** (See formula) ** in which: n is 1 or 2 in which: Y and Z, together with the two contiguous carbon atoms, form pentagonal or hexagonal cycles in which: the two atoms of the polymetin chain are cyclized by an external bridge consisting of at least two carbon or nitrogen atoms or both together while the others can be substituted or not characterized by the fact that the combinations of the general formula designated as "intermediate products" ** (See formula) ** or respectively: ** (See formula) ** in which: n is 1 or 2 in which: Z with the two nearby carbon atoms forms a pentagonal or hexagonal cycle in which: two carbon atoms of the open chain are cyclized by a bridge composed of at least two carbon or nitrogen atoms or at least one carbon atom and at least one nitrogen atom and where V is = O = N-aryl or - (O-alkoyl) 2 W is -Oh ONa -O -alkoyl -O-CO-alkoyl -O-CO-aryl or a group of substituted amines or halogen are condensed in molecular proportions with carbo-or heterocyclic combinations of 5 or 6 atoms that contain a methyl group reacting immediately to a CO group.
