Phosphoric acid derivatives, which are present as urea urethanes and contain a radical with an affinity for the binder in addition to at least one phosphoric acid ester group. Said phosphoric acid derivatives are especially suitable as wetting agents and dispersants. The derivatives are present according to the general formula (I)n nY(—O—CO—NH—R 1 —NH—CO—X—Z 1 ) g (I)n wherein Y is represented by a branched or unbranched, saturated or unsaturated organic radical containing 1 to 1000 carbon atoms, q is represented by an integer from 1 to 10, R 1 is represented by a saturated or unsaturated, branched or unbranched organic radical containing 6 to 20 carbon atoms, X is represented by NH and/or NZ 2 , Z 2 is represented by a branched or unbranched, saturated or unsaturated organic radical, Z 1 is represented by a branched or unbranched, saturated or unsaturated organic radical, which contains at least two carbon atoms and at least one phosphoric acid ester group. |
