    摘要： A dental material which is curable in a first stage to an elastic phase in which the material can be worked mechanically or surpluses removed, and in a second stage to its final form, comprising:(a) at least one polyfunctional epimine (aziridine);(b) at least one ethylenically unsaturated monomer;(c) at least one catalyst for the hot, cold, or light polymerization of the ethylenically unsaturated monomer; and(d) at least one catalyst to accelerate the polymerization of epimine (a), but which does not however influence the polymerization of (b).

    摘要： Dental materials based on polymerizable binders, which contain at least one chromophoric xerogel of the formula I: (SiO2)a(SiO1.5-Sp-X-CG)(MenOm)b  (I) in which Me represents a main-group metal of the 2nd to 3rd main groups or a transition metal of the 4th sub-group of the periodic table of elements; n being equal to 1 or 2, m being equal to 1 or 2 if n is equal to 1 and m being equal to 3 if n is equal to 2; Sp is a C1 to C10 alkylene radical or C2 to C10 oxyalkylene radical with 1 to 4 oxygen atoms or is absent; X is a compound group, such as CO—O, O—CO, CO—NH, NH—CO, O—CO—NH, NH—CO—O, NR, O or S or is absent, R being hydrogen or a C1 to C5 alkyl radical; CG is a chromophore; a is an integer from 0 to 20 and b is an integer from 0 to 5.
