Use of cationic polymers comprising quaternary nitrogen atoms as antistat in coating compositions, characterized in that the polymers are selected from the group consisting of compounds according to the formula (I), polydiallyldialkylamines and copolymers thereof, polyalkyleneimines, polyvinylimidazoles and copolymers thereof, and mixtures of these. The effect of the antistat is that dust adheres to a lesser degree to the coating of the composition. The compositions are employed more particularly in the interior architectural sector. |

1. A method of providing antistatic properties to coating compositions comprising:
incorporating one or more cationic polymers comprising quaternary nitrogen atoms as an antistat to a coating composition, wherein the one or more cationic polymers are selected from the group consisting of a) compounds according to the formula (I) b) polydiallyldialkylamines and copolymers thereof, c) polyalkyleneimines, d) polyvinylimidazoles and copolymers thereof, and e) mixtures thereof, where in formula (I) n is an integer between 5 and 500; Z is H, C1-C18 alkyl, OH, C1-C18 alkoxy, a group C(O)R10, —O—C(O)R10 or COOR10, in which R10 is H or C1-C18 alkyl; W is C1-C24 alkylene, C5-C7-cycloalkylene, —O—(CH2—O)p—, —O—(CH2—CH2—O)q—, ((CH2)z—O)t— or —CH2-T-CH2—CHZ—CH2—; T is C1-C24 alkylene, C5-C7 cycloalkylene, —O—(CH2—O)p—, —O—(CH2—CH2—O)q—, —O—(CH2)z—O—; in which p, q, z and t independently of one another are integers from 0 to 100; Y is a group in which R1 and R2 independently of one another are H, C1-C18 alkyl or C1-C18 alkylene, the alkylene group being joined to a nitrogen atom of another group Y, or R1 and R2, together with the nitrogen atom to which they are joined, denote a five-, six- or seven-membered ring or Y is a group in which R1 and R2 independently of one another are H, C1-C18-alkyl or C1-C18 alkylene, the alkylene group being joined to a nitrogen atom of another group Y, or the two radicals R1, together with T and with the nitrogen atoms to which they are joined, denote a five-, six- or seven-membered ring; and X− are halides, anions of a C1-C18 carboxylic acid, anions of an aromatic or aliphatic sulfonic acid, sulfate, anions of an aromatic or aliphatic phosphoric acid, borate, nitrate, ClO4−, PF6−, or BF4−. |
