Abstract: A dental composition comprising a polymerizable acidic compound of the following formula (I): wherein R1 which may be the same or different when more than one R1 is present, represents a hydrogen atom or a methyl group; R2 which may be the same or different when more than one R2 is present, represents a hydrogen atom, a straight-chain or branched C1-6 alkyl group, a C3-8 cycloalkyl group or a straight-chain or branched C2-6 alkenyl group; R3 which may be the same or different when more than one R3 is present, represents a monovalent organic moiety substituted by a group selected from —COOM, —PO3M, —O—PO3M2 and —SO3M, wherein M independently represents a hydrogen atom or a metal atom; or R2 and R3 form together a divalent organic moiety substituted by a group selected from —COOM, —PO3M, —O—PO3M2 and —SO3M, wherein M independently represents a hydrogen atom or a metal atom; L represents a (m+n+1)-valent organic linker group; X represents a hydrogen atom or a group selected from —COOM, —PO3M, —O—PO3M2 or —SO3M, wherein M independently is a hydrogen atom or a metal atom; m is an integer of 0 to 6; n is an integer of 0 to 6; wherein (m+n) is at least 2; provided that when n is 0, then X cannot be a hydrogen atom.
