Beschreibung
Zusammenfassung:	Aq. pigment dispersions contain, besides the usual additives, (a) pigments, (b) condensn. prods. from napthalene, HCHO and H2SO4, (c) ethylene oxide adducts with long chain amines and (d) polymsn. prodts. from ethylene oxide and propylene oxide of formula HO-(C2H4)x-(C3H6O)y-(C2H4O)z-H (I). Used for pigmenting natural and synthetic materials and esp. for coatings based on plastics dispersions and cellulose esters used for wallpaper, and also for colouring aqs. coatings based on plastics dispersions. The dispersions contain high concns. of pigment in a very high state of the division, and have good flow props. The pigments particles do not re-agglomerate or form specks on storage, such that there is no reduction in colour strength.
