A kit based on two pastes designed to produce bone cement with high initial stability and hence low post-hardening. The kit of the present invention includes paste A and paste B, wherein (a) paste A comprises (a1) a polymerizable monomer having a pH in water ranging from 5 to 9, and (a2). ) (A1) insoluble fillers; (a3) 1,5-disubstituted barbituric acid derivatives, 1,3,5-trisubstituted barbituric acid derivatives, and 1,3,5-tetrasubstituted barbiturates A barbituric acid derivative selected from the group consisting of acid derivatives, and (b) paste B comprises (b1) a polymerizable monomer having a pH in water ranging from 5 to 9, and (b2 ) Selected from the group consisting of a filler that is insoluble in (b1), a peroxide that is soluble in (b3) and (b1), and a heavy metal salt and a heavy metal complex that are insoluble in (b4) and (b1). A paste A and a paste B. At least one of the out contain halide salt. [Selection figure] None |
