Process for the manufacture of laking products with improved application properties

摘要

Process for the preparation of improved coating products based on basic dyes and heteropolyacids (PM, PTM, PSM, SM, PSTM and STM), in which the coating products in the presence of 1) primary, secondary or tertiary aliphatic amines, 2) alkylamino-C2- to C8-alkanoic acids, 3) diaryl or triarylamines, 4) acidic or neutral phosphoric acid esters based on fatty alcohols, their EO or PO / EO adducts, polypropylene glycol, polyethylene glycol or PO / EO block copolymers, 5) sulfuric acid semiesters of fatty alcohols, from their EO adducts or alkylphenol-EO adducts, 6) C8- to C20-alkanoic and alkene acids, alkylbenzenesulfonic acids, alkylnaphthalenesulfonic acids or dialkylsulfimides, 7) alkylphenol-EO adducts, alkanol-EO adducts, alkylamine-EO adducts, 8 ) Propylene glycols or PO-EO block copolymers of alkane diols or polyols or 9) Naphthols or alkylphenols are heated to 50 to 100 ° C at pH 2 to 5. Coloristically and application-technically improved pigments are obtained which are easily dispersible in printing inks. The prints have high gloss and high glaze.
