  Als     Alkylierungs-    und     Aralkylierungs-          mittel    können Verbindungen wie     Dimethyl-          srilfat,        Chlormethyl,        Bromäthyl,        p-Toluoisulfo-          säureester,        Benzylchlorid    usw. verwendet und  die     Alkylierung    oder     Aralkylierung    in wässe  riger Lösung bei einer geeigneten Tempe  ratur,     gegebenenfalls    unter Druck und vor  teilhafterweise in Gegenwart von säurebinden  den     Agentien,    durchgeführt werden.  



  Die neuen Produkte stellen mehr oder  weniger gefärbte     Verbindungen    dar, die im  allgemeinen, ohne aus der Lösung isoliert  zu     werden,    zur Verbesserung der Echtheits  eigenschaften von Färbungen verwendet wer  den können, wobei die Behandlung der     letz-          tern    sowohl in saurem, wie in alkalischem  Bade vorgenommen     werdet)    kann. Werden       Farbstofflösungen    mit den Lösungen der nach  dein vorliegenden Verfahren hergestellten  Produkte behandelt, so     entstehet)    gefärbte  Niederschläge, die im allgemeinen gegen       Alkalien    beständig sind.

   Die so erhaltenen  gefärbten Additionsprodukte können für ver  schiedene Zwecke verwendet werden.    Das vorliegende Verfahren betrifft die  Darstellung einer neuen     Pyridiniumverbindung     und ist dadurch gekennzeichnet, dass man       2,4-Diaminophenylpyridinium-l-clilorid-chlor-          hydrat    mit Formaldehyd behandelt.  



  Die neue Verbindung ist ein dunkel  braunes Harz, welches in Säuren leicht lös  lich ist. Sie besitzt die Eigenschaft, die     Echt-          heiten    der Färbungen mit     Substantiven    Farb  stoffen auf Zellulose zu erhöhen.  



       Beispiel:     13 Teile     2,4-Diaminophenylpyridinium-          1-chlorid-chlorhydrat    werden in 30 Teilen  Wasser gelöst und bei<B>500</B> C unter Rühren       n)it    15 Teilen 35     o/oiger        Formaldehydlösung     versetzt. Nach etwa     2'/s    Stunden wird  neutralisiert, mit 12 Teilen Soda alkalisch  gemacht und weitere     2'/a    Stunden bei<B>500</B> C  gerührt. Es scheidet sich dabei ein dunkel  brauner Niederschlag ab, der in Säuren leicht  löslich ist. Das dabei erhaltene Konden  sationsprodukt wird durch     Zusatz    von Säure  in Lösung gebracht.

   Dieselbe besitzt die  Eigenschaft, die     Echtheiten    der Färbungen  mit     substautiven    Farbstoffen auf Zellulose       z)i    erhöhen.



  Process for the preparation of a pyridinine compound. It has been found that valuable pyridinium compounds can be obtained by using compounds of the general formula
EMI0001.0003
    in which X is hydrogen, nitro, halogen or amino groups, condensed with aldehydes or alkylolureas and the condensation products thus obtained are treated with alkylating, aralkylating or acylating agents, if appropriate.

   If bodies from both groups are used, the amines can be treated in any order. You can z. B. first alkylate or acylate and then condense with aldehydes or Alkylolbarnstoffen kon. The compounds obtained in this way have the property of reacting with water-heavy or acidic dyes containing water-soluble sulfo groups. -to form insoluble addition compounds; they can therefore increase the fastness properties, such as water.

   Sweat and wash fastness of dyeings on various textile materials or on substrates can be used.



  As starting materials for the preparation of the new compounds, the aminopher) ylpyridiniumder-ivate, respectively, which are readily available by reduction of mono- or polynitrophenylpyridinium compounds their substitution products, which can carry substituents in the pbenyl as well as in the pyridine nucleus, are used.



  Suitable condensation of such amines with aldehydes such as formaldehyde, acetaldehyde, benzaldehyde, etc., or with urea derivatives such as dimethylolurea, dimethylolthio-urea, etc. give rise to high molecular weight compounds; which can advantageously be converted into highly effective ammonium pyridinium compounds by alkylation or peralkylation. Valuable and effective products, some of which have a soap-like character, who. the z. B. obtained by z. B.

         2,4-Diaininopliei) yl-l-pyr @ idiniunichlorid condensed first with aldehydes or alkylolureas and then with an acid chloride of a high molecular weight fatty acid, such as stearyl chloride, chlorides of coconut fatty acids, or with another organic acid chloride, such as p-toluenesulfochloride, Benzoyl chloride, acetyl chloride, chloroacetyl chloride, etc.

       acylated and optionally peralkylated or first aralkylated and then peralkylated.



  As alkylating and aralkylating agents, compounds such as dimethylsrilfate, chloromethyl, bromoethyl, p-toluoisulfonic acid ester, benzyl chloride, etc. can be used and the alkylation or aralkylation in aqueous solution at a suitable temperature, optionally under pressure and advantageously in The presence of acid-binding agents.



  The new products are more or less colored compounds which in general, without being isolated from the solution, can be used to improve the fastness properties of dyeings, the latter being treated both in acidic and alkaline baths can be made). If dye solutions are treated with the solutions of the products manufactured according to the present process, colored precipitates are formed which are generally resistant to alkalis.

   The colored addition products thus obtained can be used for various purposes. The present process relates to the preparation of a new pyridinium compound and is characterized in that 2,4-diaminophenylpyridinium-1-chloride chlorohydrate is treated with formaldehyde.



  The new compound is a dark brown resin that is easily soluble in acids. It has the property of increasing the authenticity of the dyeings with noun dyes on cellulose.



       Example: 13 parts of 2,4-diaminophenylpyridinium-1-chloride chlorohydrate are dissolved in 30 parts of water and 15 parts of 35% formaldehyde solution are added at <B> 500 </B> C with stirring. After about 2 ½ hours, the mixture is neutralized, made alkaline with 12 parts of soda and stirred at 500 C for a further 2 ½ hours. A dark brown precipitate separates out, which is easily soluble in acids. The resulting condensation product is brought into solution by adding acid.

   The same has the property of increasing the fastness of the dyeings with substantial dyes on cellulose z) i.
