Abstract
Pigmented molding compositions having good weatherability for sheet and bulk molded articles are made by mixing a resin component comprising an unsaturated polyester, a monomer which will react with the polyester and a non-aromatic, thermoplastic polymer; an ultraviolet light absorbing material and/or a hindered amine light stabilizing material; a pigment; and a reinforcing agent.
