The invention relates to a dental material which comprises a thermolabile or photolabile polymerizable compound of the formula (I): [(Z 1 ) n -Q 1 -X)] k -T-[Y-Q 2 -(Z 2 ) n ] l (formula (I)), in which T is a thermolabile or photolabile group, Z 1 and Z 2 each independently are a polymerizable group selected from vinyl groups, CH 2 =CR 1 -CO-O- and CH 2 =CR 1 -CO-NR 2 - or are an adhesive group selected from -Si(OR) 3 , -COOH, -O-PO(OH) 2 , -PO(OH) 2 , -SO 2 OH and -SH, with at least one Z 1 or Z 2 being a polymerizable group, Q 1 independently in each case is absent or is an (m+1)-valent linear or branched aliphatic C 1 -C 20 radical, which may 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 independently in each case is absent or is an (n+1)-valent linear or branched aliphatic C 1 -C 20 radical, which may 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 absent or are -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 -, R, R 1 , R 2 and R 3 each independently are H or C 1 -C 7 alkyl radical, and k, l, m and n each independently are 1, 2 or 3. |
