  • Patent number: 8969438
    Abstract: Non-aqueous pigment concentrate comprising one or more pigments, one or more dispersants, and at least one resin, characterized in that the resin is a polyester comprising at least one oligo-ester building block with a hydrophobic tail linked thereto, wherein the hydrophobic tail is selected from the group consisting of: (a) branched hydrocarbons, (b) hydrocarbons containing a cyclic group, and (c) linear hydrocarbons, provided that when said linear hydrocarbon is linked to the oligo-ester building block via an ester group, the linear hydrocarbon contains 3 to 12 carbon atoms.
