  • Patent number: 12129390
    Abstract: The embodiments herein provide a solvent borne pigment paste comprising an alkyd, where the alkyd is obtainable by a process including the steps of a. producing an OH-functional alkyd from a non-drying oil or fatty acid, one or more polyols, and a first anhydride; where the non-drying oil or fatty acid has an iodine number ?115; b. esterification of the OH-functional alkyd with trimellitic anhydride (TMA), where at least 80% of the esterified TMA residues has two free carboxylic groups. In some embodiments, at least 85%, at least 90%, or at least 98% of the esterified TMA residues has two free carboxylic groups.
