Abstract:
Dental material which contains a polymerizable phthalic acid derivative of the general Formula I: with R1=H, methyl or a C1-C5 alkyl residue; R2=H, a phenyl, benzyl or C1-C8 alkyl residue; Q1=is absent or is a C1-C15 alkylene residue, wherein the carbon chain can be interrupted by O or S; Q2=is absent or a (n+1)-valent aliphatic C1-C20 residue, wherein the carbon chain can be interrupted by O or S and wherein Q1 and Q2 cannot be absent simultaneously; X=is absent, is O, S or (—CO—NR4—)—, wherein R4 is H, CH3 or C2H5; Y=is absent, is O, S or (—CO—NR5—)—, wherein R5 is H, CH3 or C2H5; n, m=independently of one another in each case mean 1, 2 or 3; R3=H, CH3, C2H5, Cl, Br or OCH3, and wherein the two carboxyl groups of the benzene ring can together form an anhydride group.
