Abstract:
The present invention relates to an aqueous dental composition having a pH of less than 7 as well as to the use of a stabilizer for the preparation of an aqueous dental composition having a pH of less than 7. In particular, the present invention relates to an aqueous dental composition having a pH of less than 7 comprising (i) one or more polymerizable compounds having at least one polymerizable double bond; (ii) a polymerization initiator system containing a) an 1,2-diketone photoinitiator compound having a light absorption maximum in the range from 300 to 500 nm; and b) a coinitiator compound; (iii) a stabilizer of the following formula (I) and/or (II), wherein the Rs, which may be the same or different, independently represent a branched C 3-8  alkyl or alkenyl group, or a C 3-8  cycloalkyl or cycloalkenyl group, R′ represents a hydrogen atom, a C 1-6  alkyl or C 2-6  alkenyl group, or a C 1-6  fluoroalkyl or C 2-6  fluoroalkenyl group, X represents a group selected from a C 1-8  alkyl group or a C 3-8  cycloalkyl group, and n is 0, 1 or 2; and a solvent mixture comprising an organic solvent and at least 1 percent by weight of water based on the total weight of the aqueous dental composition.

Claim (Index 3):
The aqueous dental composition according to  claim 1  or  2 , wherein the polymerization initiator system further comprises one or more compounds selected from the following group:\n (1) an iodonium compound of the following formula (III):\n R 7 \u2014I + \u2014R 8 A \u2212 \u2003\u2003(III) \n wherein \n R 7  and R 8  \n which are independent from each other, represent an organic moiety, and \n \n A \u2212  is an anion; \n \n (2) a sulfonium compound of the following formula (IV):\n R 9 R 10 R 11 S + A \u2212 \u2003\u2003(IV) \n wherein \n R 9 , R 10  and R 11  \n which are independent from each other, represent an organic moiety or wherein any two of R 9 , R 10  and R 11  form a cyclic structure together with the sulfur atom to which they are bound, and \n \n A \u2212  is an anion; \n \n (3) a phosphonium compound of the following formula (V):\n R 12 R 13 R 14 P + A \u2212 \u2003\u2003(V) \n wherein \n R 12 , R 13  and R 14  \n which are independent from each other, represent an organic moiety, and \n \n A \u2212  is an anion; and \n \n (4) a pyridinium salt.
