A polymethylmethacrylate bone cement with a liquid monomer component and a solid component contains in the monomer liquid, for example, 0.001-1.00 mass perce nt of a dye or dye mixture that is insoluble or poorly soluble in methacrylic acid methylester and, for example, 0.001-2.00 mass percent of a synthetically produced, protein-free, hydrophobic, low molecular or oligomeric solubilizer for the dye or dye mixture. The solubilizer preferably is liquid or pasty at room temperature. The monomer liquid is translucent at room temperature. Preferably, 0.001-1.00 mass percent of a dye or dye mixture that is insoluble or poorly soluble in methacrylic acid methylester and, preferably, 0.001-2.00 mass percent of a synthetically produced, protein-free, hydrophobic, low molecular or oligomeric solubilizer that is liquid or pasty at room temperature are homogeneously dissolved in the polymethacrylate or polymethylacrylate of the powder component.
