Abstract

Dental composition comprising a water-soluble polymerizable compound of the following formula (1): wherein A is a linear or branched linker group represented by the following formula (3), wherein the nitrogen atom of at least two of the termini forms an amide bond with an X moiety; wherein R′ represents a hydrogen atom or a substituted or unsubstituted aliphatic or cycloaliphatic hydrocarbon group, wherein each R may be the same or different L1, L2, and L3 which may be the same or different, independently represent a single bond, or a C2-20 straight-chain, branched or cyclic hydrocarbon group optionally containing from 1 to 6 heteroatoms selected from nitrogen and oxygen in the backbone of the hydrocarbon group, and optionally from 1 to 6 functional groups selected from carboxylic acid groups or a salt thereof, hydroxyl groups, thiol groups and amino groups, and in case a plurality of L1 and L2 are present, each of L1 and L2 may be the same or different; Q1 and Q2, which may be the same or different, independently represent a single bond or a linkage selected from an amide, a urethane, a urea and a thiourea linkage; k is an integer of at least 0, X are moieties containing a polymer…
