Читать книгу Additives for Water-borne Coatings - Wernfried Heilen - Страница 34

The classical way of producing printing inks involves a resin solution based on an acidic styrene-acrylic or pure-acrylic resin neutralised with amines to make it water soluble. The resin solution is able to stabilise pigments very well, but pigment wetting is sometimes not acceptable. This is apparent particularly with carbon black pigments where the viscosity is very high and the colour strength quite poor so that use of suitable additives with good wetting is advantageous.
