Claim 0:
1. A reaction product containing urethane and urea groups, comprising at least one species of the general formula (I), where a is an integer and is 1 or 2,
b is an integer and is 1 or 2,
x is an integer and is 2 or 3,
and

R is the organic radical of a corresponding polyisocyanate R(NCO)x, R is a branched or unbranched, saturated or unsaturated organic radical having 1 to 150 carbon atoms and does not contain any free isocyanate groups,
the Y radical(s) is/are independently the organic radical(s) of a corresponding alcohol Y(OH)q where q is an integer and is 1 and Y is a branched or unbranched, saturated or unsaturated organic radical having 1 to 1000 carbon atoms, wherein the Y radicals are selected from the group consisting of polyether radical based on ethylene oxide, propylene oxide, and mixtures thereof, and having a number-average molecular weight of 200 to 10,000 g/mol, polyester radical obtained by polycondensation of one or more optionally alkyl-substituted hydroxycarboxylic acids or ring-opening polymerization of the corresponding lactones, and having number average molecular weight Mn in the range of 150 to 5,000 g/mol, and hydrocarbyl radical, wherein the hydrocarbyl radical is the hydrocarbyl group of at least one of methanol, ethanol, butanol, ethylhexanol, decanol, isotridecyl alcohol, lauryl alcohol, stearyl alcohol, isobornyl alcohol, benzyl alcohol, propargyl alcohol, oleyl alcohol, linoleyl alcohol, oxo alcohols, neopentyl alcohol, cyclohexanol, fatty alcohols, alkylphenols, alkylnaphthols, and phenylethanol,
the A radical(s) is/are independently a radical of the general formula (II), where
the R1 radical is H or a branched or unbranched, saturated or unsaturated organic radical having 1 to 25 carbon atoms,
the Za group is N,
the Zb group is N or CH, and
the R2 radical is H.
