1. A non-pigmented composition comprising: 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 unit 1,
![]() and the second block comprises repeating unit 2,
![]() wherein
Z represents O or NH,
R1 represents H or CH3,
R2 represents a hydrocarbyl group or an ether group-containing group,
R3 represents an organic group having 2 to 4 carbon atoms,
R4 and R5 independently represent an organic group, wherein R4 and R5 are optionally linked to each other to form a cyclic structure, and
a polymer comprising at least one acidic group, and having a number average molecular weight of 300 g/mol or higher,
wherein the repeating unit 2 of the block co-polymer is at least partially present as salt of the polymer comprising the at least one acidic group, and
wherein the composition is essentially free of pigments, dyes, and inorganic filler materials.
