A one-part self-etching, self-priming dental adhesive having a pH of at most2, which comprises an aqueous mixture containing (i) one or more polymerizablemonomers optionally containing an acidic group, (ii) optionally one or moreorganic or inorganic acids, (iii) a polymerization initiator, and (iv) a thermalPolymerisation inhibitor of the following formula (I): wherein R’represents a hydrogen atom, or a saturated hydrocarbon group having 1 to 18 carbonatoms. R', which may be the same or different if more than oneR' is present, independently represent a saturated hydrocarbongroup having 1 to 18 carbon atoms, and c represents an integer of from 1 to 4.
