The invention relates to a process for preparing a pigmented curable molding compound comprising mixing together an unsaturated polyester resin, a thermoplastic polymer, a color paste and optionally a filler, and is characterized in that the color paste is obtained by dissolving pigment particles in a solution of a thermoplastic polymer in a suitable solvent. The invention further relates to the color paste itself and to homogeneously and uniformly colored moldings obtained thereform.

Method for the preparation of pigmented curable polyester molding compounds

The invention relates to a process for preparing a conductive curable moulding compound with reduced electrical surface resistance, comprising mixing together an unsaturated polyester resin, a thermoplastic polymer, a conductive paste and optionally a filler, and is characterized in that the conductive paste is obtained by dispersing conductive pigment particles in a solution of a thermoplastic polymer in a suitable solvent. The invention further relates to the conductive paste itself and to mouldings having reduced surface resistance, obtained therefrom.

Method for the apparatus of conductive curable polyester moulding

Moldings having improved surface properties are produced using BMC molding materials which contain crystalline unsaturated polyesters.

Molding ofBMC molding materials having improved surface properties

A curable thickened polyester resin molding compound contains from 0.1 to 20 parts by weight of a thermoplastic vinyl polymer which is compatible with the resin and contains acid groups.

Thickened curable molding compound of unsaturated polyester resins

An electrophotographic recording medium which consists essentially of an electrically conductive base and a photosemiconductive double layer which comprises a first layer containing charge carrier-producing dyes, and a second layer containing one or more compounds which are charge carrier-transporting when exposed to light, wherein the charge carrier-producing dyes are those of the general formula I ##STR1## where R.sup.1, R.sup.2 and R.sup.3 are each hydrogen, halogen, alkyl, nitro or cyano, R.sup.4 is phenyl, halophenyl, alkylphenyl, nitrophenyl or dialkylaminophenyl, and X is oxygen, sulfur, NH or N-phenyl, and the production of this recording medium.
