摘要:
Solid preparations of organic pigments are obtained from aqueous systems which contain the pigment or in which it has been formed by adding to this system a polysaccharide having anionic groups and an affinity for this pigment, removing the treated pigment from this aqueous system and drying it. These preparations are useful for pigmenting hydrophilic media, especially aqueous or water-dilutable paints and coating agents, printing inks and printing pastes. The preparations can be prepared and processed without any great mechanical expenditure.
摘要:
By coupling diazotized amines of the benzene series onto acetoacetic acid arylides, in which process more than one diazo and/or coupling component is applied and from 0.1 to 20 molar % of the diazo and/or coupling component contain acid groups, and by subsequently reacting the reactive acid groups of the product obtained by coupling with cation-active quaternary compounds, recrystallization-resistant monoazo pigment mixtures are obtained which are suitable for the preparation of varnishes, printing inks, and oily and aqueous compositions.
摘要:
Condensation products, which can be obtained by a reaction of naphthols and alkanals, addition of alkylene oxides and more or less complete conversion of terminal hydroxy groups into sulfo groups or half-esters of maleic acid, phthalic acid or sulfosuccinic acid, are suitable for use as surface-active agents, in particular as coupling auxiliaries in the preparation of azo pigments and also as dispersing agents in the preparation of colorant dispersions and as wetting, emulsifying, leveling or dyeing auxiliaries.
