A composition, such as a pigment dispersion or coating composition, includes a pigment and a wetting additive. The wetting additive includes a first agent and a second agent. The first agent has the following formula: X(AO)mH wherein X is a C6 to C16 branched chain, A is an alkylene group selected from the group of ethylene groups, propylene groups, butylene groups, and combinations thereof, and m is from about 3 to about 20. The second agent is different from the first agent and has the following formula: Y(A'O)nH wherein Y is a C6 to C16 linear chain, A' is an alkylene group selected from the group of ethylene groups, propylene groups, butylene groups, and combinations thereof, and n is at least about 3. The second agent has a triblock (A''O)p(EO)q(A''O)r configuration in the portion represented by (A'O)n, wherein A'' is selected from the group of propylene groups, butylene groups, and combinations thereof and wherein p, q, and r are each independently at least 1. |
