摘要

Phenyl-substituted polysiloxanes (I) are used to prepare aqueous pigment formulations, lacquers and coatings. Phenyl-substituted polysiloxanes of formula (I) are used to prepare aqueous pigment formulations, lacquers and coatings: R-Si(CH3)2-O-(Si(CH3)2-O)a-(Si(CH3)2-O)-Si(CH3)2-R (I) R = R1 or Me; R1 = (CH2)cO(CH2CH(Ar)O)e(CnH2n-xO)dR3 or CH2CHR'Ar; R' = H or Me; R2 = 1-5C alkyl; Ar = phenyl substituted with 0-5 of OH, 1-6C alkyl or 1-6C alkoxy; R3 = H, 1-18C alkyl, benzyl, alkylbenzyl, COR5, CONHR6 or COOR7; R5, R7 = 1-18C alkyl; R6 = H or 1-18C alkyl; c = 2-6; d = 3-70; e = 0 or more; n = 2-4; a = 0-100; b = 1-100; provided that b is more than 1 when e = 0. An Independent claim is also included for aqueous pigment formulations containing (I).
