ABSTRACT:
The invention concerns a thermosetting polyester resin capable of forming an anisotropic molten phase comprising a repeating unit of the formula: A-X-B alone, or a combination of the repeating unit of the formula: A-X-B and the repeating unit of the formula: R, adjoining two repeating units being connected each other through an ester bond, in which A represents a mesogenic group defined in the specification, B is a spacer group defined in the specification, X is an ester bond, and R represents a bivalent to hexavalent aliphatic, aromatic or alicyclic hydrocarbon residue, the end bondings of the connected repeating units being occupied by OH, COOH or their reactive derivatives and the sum of the resinous acid value and the OH value being 10 to 200.
The invention also provides a powder coating resinous composition containing the abovesaid resin.
