A grind resin, a pigment dispersion, and a coating composition are provid ed. The grind resin comprises a reaction product of a dibasic acid, optional ly a polybasic acid, a diol, optionally a polyol, and a fatty compound. The fatty compound has a fatty chain and two reactive groups reactive with at le ast one of the dibasic acid and the diol provided that <= 5% of all acid groups are provided by the polybasic acid and < 20% of all hydroxyl group s are provided by the polyol. The reaction product is substantially free fro m branching comprising a reaction product of acid groups or hydroxyl groups and the dibasic acid, polybasic acid, diol, polyol, or fatty compound. The p igment dispersion comprises a pigment and the grind resin. The coating compo sition comprises a vehicle resin, the pigment, the grind resin, and a cross- linking agent reactive with the vehicle resin and/or the grind resin.
