1. resin combination, which contains:

  • (A) terminal carboxyl group amount is 30 equivalents/ton aromatic polyester resin below, that is, A ingredient;

    (B) at least have cyclic carbodiimide compounds, that is, B component there are two carbodiimides ring, the carbodiimidesOnly one carbonization diimino in one ring of ring;

    And(C) for ether obtained from addition polymerization epoxyalkane (C-ii) is at least selected from fatty acid glyceride (C-i) and on two glycerolA kind of compound, and hydroxyl value be 200 or more and 600 it is below contain polyol, that is, C ingredient,On the basis of the A ingredient of 100 mass parts, the content of B component is 0.1 ~ 3 mass parts, and the content of C ingredient is 0.05 ~ 2 massPart,The resin combination is formed as follows;

    (i) after being kneaded by aromatic polyester resin, that is, A ingredient and containing polyol, that is, C components fuse, to resulting mixtureMiddle addition cyclic carbodiimide compounds, that is, B component carries out melting mixing;

    Or(ii) cyclic carbodiimide compounds i.e. B component is added simultaneously into aromatic polyester resin, that is, A ingredient and containing polyhydroxyCompound, that is, C ingredient carries out melting mixing.
