chemical industry. SUBSTANCE: described is dispersant which is phosphoric acid ester of block copolymer of formula 1 RO(C2H4O)m(PEn)-H, where R is C1-4 alky; polyether with repetitive group ; m is integer from 4 to 60; n is integer from 2 to 30, molecular weight of RO(C2H4O)m is greater than molecular weight of PEn. Also described is preparation and use of said dispersant which is capable of dispersing large amounts of solid phase macroparticles in medium. EFFECT: improved properties of dispersant, higher stability of dispersion and superior properties of resulting colorful film, especially higher final luster. 11 cl, 6 tbl, 8 ex |
