Preparation of lakes having improved performance characteristics

Improved lakes based on basic dyes and heteropolyacids (PM, PTM, SM, PSTM and STM) are prepared by a process in which the lakes are heated to 50 DEG -100 DEG C. at pH 2-5 in the presence of (1) primary, secondary or tertiary aliphatic amines, (2) alkylamino-C2-C8-alkanoic acids, (3) diaryl- or triar...

Zusammenfassung:	Improved lakes based on basic dyes and heteropolyacids (PM, PTM, SM, PSTM and STM) are prepared by a process in which the lakes are heated to 50 DEG -100 DEG C. at pH 2-5 in the presence of (1) primary, secondary or tertiary aliphatic amines, (2) alkylamino-C2-C8-alkanoic acids, (3) diaryl- or triarylamines, (4) acidic or neutral phosphates based on fatty alcohols, their ethylene oxide or propylene oxide/ethylene oxide adducts, polypropylene glycol, polyethylene glycol, or propylene oxide/ethylene oxide block copolymers, (5) sulfuric acid half esters of fatty alcohols, of their ethylene oxide adducts or alkylphenol/ethylene oxide adducts, (6) C8-C20-alkanoic acids and alkenoic acids, alkylbenzenesulfonic acids, alkylnaphthalenesulfonic acids or dialkylsulfimides, (7) alkylphenol/ethylene oxide adducts, alkanol/ethylene oxide adducts or alkylamine/ethylene oxide adducts, (8) propylene glycols or propylene oxide/ethylene oxide block copolymers of alkanediols or -polyols or (9) naphthols or alkylphenols. The pigments obtained possess improved tinctorial properties and performance characteristics and are readily dispersible in printing inks. The prints exhibit high gloss and high transparency.
