The invention relates to a comb polymer having a polymer backbone and lateral side chains linked to the polymer backbone, wherein the lateral side chains comprise a) alkyl ether terminated polyalkylene oxide side chains, and b) tertiary amine-functional side chains, wherein the tertiary amine groups are at least partly neutralized by an acid having a molecular weight in the range of 100 g/mol to 2000 g/mol, wherein the molecular weight relates to the number average molecular weight Mn in the case of polymeric acids, and wherein the lateral side chains a) and b) are distributed in random order.

Comb polymer having salt groups

The invention relates to a non-pigmented composition comprising a) a block co-polymer comprising at least one first block and at least one second block which is different from the first block, wherein the first block comprises repeating units 1, repeating unit 1 and the second block comprises repeating units 2, repeating unit 2 wherein Z represents O or NH, Rrepresents H or CH, Rrepresents a group selected from hydrocarbyl groups and ether group-containing groups, Rrepresents an organic group having 2 to 4 carbon atoms, Rand Rindependently represent an organic group, wherein Rand Rare optionally linked to each other to form a cyclic structure, and b) a polymer comprising at least one acidic group, and having a number average molecular weight of 300 g/mol or higher.
