The invention relates to a dental restorative material which comprises a thermolabile compound of Formula I: n [(Z 1 ) m -Q 1 -X)] k -T-[Y-Q 2 -(Z 2 ) n ] l Formula I,n n in which T represents a thermolabile unit which contains at least one thermolabile group based on non-covalent interactions, Z 1 and Z 2 in each case independently represent a polymerizable group selected from vinyl groups, CH 2 ═CR 1 —CO—O— and CH 2 ═CR 1 —CO—NR 2 — or an adhesive group selected from —Si(OR) 3 , —COOH, —O—PO(OH) 2 , —PO(OH) 2 , —SO 2 OH and —SH, Q 1 in each case independently is missing or represents an (m+1)-valent linear or branched aliphatic C 1 -C 20 radical which can be interrupted by —O—, —S—, —CO—O—, —O—CO—, —CO—NR 3 —, —NR 3 —CO—, —O—CO—NR 3 —, —NR 3 —CO—O— or —NR 3 —CO—NR 3 —, Q 2 in each case independently is missing or represents an (n+1)-valent linear or branched aliphatic C 1 -C 20 radical which can be interrupted by —O—, —S—, —CO—O—, —O—CO—, —CO—NR 3 —, —NR 3 —CO—, —O—CO—NR 3 —, —NR 3 —CO—O— or —NR 3 —CO—NR 3 —, X and Y in each case independently are missing or represent —O—, —S—, CO—O—, —O—CO—, —CO—NR 3 — or —NR 3 —CO—, R, R 1 , R 2 and R 3 in each case independently represent H or a C 1 -C 7 alkyl radical, k and l in each case independently are 0, 1, 2 or 3 and m and n in each case independently are 1, 2 or 3. |
