  • Patent number: 6787581
    Abstract: The invention relates to powder coating material curable with high-energy radiation, comprising an unsaturated polyester resin (A) and a polymeric crosslinker (B) containing, based on the polymer main chain, terminal and/or pendant propenyl, butenyl and/or isoprenyl groups. The unsaturated polyester resin (A) and/or the polymeric crosslinker (B) comprise structural units of the general formula I and/or II. These novel powder coating materials are curable with high-energy radiation, preferably UV light, and are notable in particular for a very good viscosity stability during the preparation, in the melt, of the resins and the compounding of the coating materials, for outstanding coating properties, and for a low oxygen sensitivity on curing. The films resulting after the cure, moreover, exhibit outstanding elasticity.
