1. Dental restorative material which comprises at least one compound of Formula I
A-[X-Q-(Y-CG)n]m Formula I, wherein A represents —O—, —N═, —NR3—, ═N—N═, —NR3—N═, ═N—NR3—, —NR3—NR3— or an m-valent alkylene radical, cycloalkylene radical, heterocycloalkylene radical, arylene radical, heteroarylene radical, mixed alkylene-cyclyl radical or cyclyl-O-cyclyl radical, wherein
alkylene represents in each case independently a linear or branched aliphatic C1-C50 radical which can be interrupted by one or more —O—, —S—, —NR3—, —CO—O—, —O—CO—, —O—CO—O—, —CO—NR3—, —NR3—CO—, —O—CO—NR3—, —NR3—CO—O— or —NR3—CO—NR3—,cycloalkylene represents in each case independently a cycloaliphatic C3-C18 radical,heterocycloalkylene represents in each case independently a heterocycloaliphatic C3-C18 radical,arylene represents in each case independently an aromatic C6-C18 radical,heteroarylene represents in each case independently a heteroaromatic C3-C18 radical,cyclyl represents in each case independently cycloalkylene, heterocycloalkylene, arylene or heteroarylene andthe indicated radicals in each case independently can carry one or more substituents, CG represents in each case independently an azide group N3 or an alkyne group selected from the group consisting of —CR1R2—C≡CH, with the proviso that the dental restorative material comprises at least one compound of Formula I comprising an azide group and at least one compound of Formula I comprising an alkyne group, Q in each case independently is missing or represents an (n+1)-valent linear or branched aliphatic C1-C20 alkylene radical which can be interrupted by one or more —O— or —S—, or a phenylene radical, wherein the indicated radicals in each case independently can carry one or more substituents, R1, R2 and R3 in each case independently represent H or a C1-C10 alkyl radical, X and Y in each case independently are missing or represent —O—, —S—, —NR3—, —CO—, —CO—O—, —O—CO—, —O—CO—O—, —CO—NR3—, —NR3—CO—, —O—CO—NR3—, —NR3—CO—O— or —NR3—CO—NR3—, m in each case independently can assume the values 2 to 6 and n in each case independently can assume the values 1 to 4.
