The invention relates to an aqueous dispersion containing a pigment (B) that is at least partially sheathed in at least one radiation-curable polyurethane (A). Said radiation-curable polyurethane (A) is obtained by the reaction of (a) at least one diisocyanate with (b) at least one compound comprising at least two groups that are capable of reacting with isocyanate and (c) at least one compound of general formula (I), in which the variables are defined as follows: R1 and R2 are identical or different and selected independently of one another from hydrogen and C1-C10 alkyl; X1 is selected from oxygen and N-R3; A1 is selected from C1-C20 alkene, which is unsubstituted or mono- or polyvalently substituted by C1-C4 alkyl, phenyl or O-C1-C4 alkyl, whereby in the C1-C20 alkene one or more non-adjacent CH2 groups can be replaced by oxygen; X2 is selected from hydroxyl and NH-R3, where R3 is identical or different and selected from hydrogen, C1-C10 alkyl and phenyl.

摘要:
The invention relates to amphiphilic polymer compositions, to a method for their production and to their use for producing aqueous active ingredient compositions of water-insoluble active ingredients, in particular active ingredients for crop protection. The amphiphilic polymer compositions are obtained by reacting a) at least one hydrophobic polymer P1, which carries functional groups R1 that are reactive in relation to isocyanate groups and which is composed of ethylenically unsaturated monomers M1, comprising: a1) at least 10 wt. %, (in relation to the total quantity of the monomers M1), of monomers M1a of general formula (I), in which X represents oxygen or an N-R4 group; R1, R2, R3, and R4 are defined as cited in the claims and the description; a2) up to 90 wt. %, (in relation to the total quantity of the monomers M1) of neutral, monoethylenically unsaturated monomers M1b, whose solubility in water at 25 °C is less than 50 g/l and which differ from the monomers M1a; and a3) up to 30 wt. %, (in relation to the total quantity of the monomers M1, of ethylenically unsaturated monomers M1c, which differ from the monomers M1a and M1b, b) at least one hydrophilic polymer P2, which carries functional groups R2 that are reactive in relation to isocyanate groups, c) with at least one compound V, which has a functionality of at least 1.5 in relation to the isocyanate groups.
