    Abstract: The invention relates to an aqueous impregnating resin solution containing (A) between 77.5 and 99.8 wt. %, in relation to the impregnating resin solution, of aqueous condensates based on melamine and formaldehyde; (B) between 0.1 and 20 wt. %, in relation to the impregnating resin solution, of at least one specific quaternary ammonium compound; and (C) between 0.1 and 2.5 wt. %, in relation to the impregnating resin solution, of an aqueous hardener solution. The invention also relates to an aqueous impregnating resin solution consisting of constituents (A) and (B), and to an aqueous hardener mixture consisting of constituents (B) and (C). The invention further relates to an impregnating resin film containing fibrous substances containing cellulose and impregnated with the aqueous impregnating resin solution, and to the use of the aqueous impregnating resin solution, or impregnating resin film, for the antistatic finishing of coated materials.

    Abstract: Processes comprising: providing an alkanolic reaction mixture, the alkanolic reaction mixture comprising: at least one alkoxycarbonylaminotriazine; at least one carbonic ester; at least one C1-C13-alkanol, which alkanol may further comprise up to two ether-bound oxygen atoms and may further comprise a substituent selected from the group consisting of C1-C4-alkyls and hydroxyls; and at least one alkali metal alkoxide or alkaline earth metal alkoxide; and subjecting the alkanolic reaction mixture to extraction with a polar extractant such that at least a portion of polar/ionic components present in the reaction mixture are removed, wherein the polar extractant is less than entirely miscible with an organic phase of the reaction mixture, to form an alkanolic phase comprising the at least one alkoxycarbonylaminotriazine and a polar phase comprising the polar extractant and the portion of polar/ionic components; and wherein the extraction is carried out with one or more selected from the group consisting of mixer/settler units, columns, centrifugal field separation extractors, and combinations thereof.

    IPC: C07D251/70

    Abstract: The invention relates to a process for preparing free-flowing, pulverulent alkoxycarbonylaminotriazine from an alkanolic reaction mixture which is obtained in the preparation of alkoxycarbonylaminotriazines and comprises at least one alkoxycarbonylaminotriazine, at least one cyclic and/or acyclic carbonic ester, at least one C1-C13-alkanol which optionally comprises one or two oxygen atoms in the form of ether bonds and is optionally substituted by C1-C4-alkyl and/or hydroxyl, and also at least one alkali metal or alkaline earth metal alkoxide, with or without melamine and with or without catalyst, by atomizing and drying the reaction mixture in a spray drier.
