| 摘要 |
The present invention relates to powdered thermosetting compositions including a binder which comprises a carboxyl group containing amorphous isophthalic acid containing polyester, a carboxyl group containing aliphatic semi-crystalline polyester, an optional and different carboxyl group containing semi-crystalline polyester, at least 5 parts by weight, based on the total weight of the binder, of a specific glycidyl group containing acrylic copolymer and a curing agent having functional groups reactive with the polyesters' carboxyl groups. The powdered thermosetting compositions are useful for the preparation of powdered paints and varnishes which give semi-matt coatings having an outstanding flow, a remarkable weatherability and excellent mechanical properties.
