Disclosed is a novel compound (I) represented by the general formula (1) which has a polymerizable group, a carboxyl group and a phosphate group and can be suitable used in a dental composition. Also disclosed is a process for producing a polymerizable amide, which can allow the condensation reaction between a carboxylic acid and an amine to proceed readily and is highly safe. (1) wherein R1, R2 and R3 independently represent a hydrogen atom or a hydrocarbon group having 1 to 20 carbon atoms which may have a substituent; (A) and (B) independently represent an arbitrary constituent unit; m represents an integer of 1 to 3; n represents an integer of 1 to 3; R4 represents an organic group having 1 to 40 carbon atoms which may have a substituent; R5 represents a hydrocarbon group having 1 to 20 carbon atoms which may have a substituent; and R6 and R7 independently represent a hydrogen atom, a hydrocarbon group having 1 to 20 carbon atoms which may have a substituent or a metal atom.

L'invention concerne un nouveau composé (I) représenté par la formule générale (1) qui présente un groupe polymérisable, un groupe carboxyle et un groupe phosphate et peut être utilisé de façon appropriée dans une composition dentaire. L'invention concerne également un procédé de fabrication d'un amide polymérisable, qui peut permettre à la réaction de condensation entre un acide carboxylique et une amine de se dérouler facilement et est sans danger. (1) Formule dans laquelle R1, R2 et R3 représentent indépendamment un atome d'hydrogène ou un groupe hydrocarboné ayant 1 à 20 atomes de carbone qui peut avoir un substituant ; (A) et (B) représentent indépendamment une unité constitutive arbitraire ; m représente un entier de 1 à 3 ; n représente un entier de 1 à 3 ; R4 représente un groupe organique ayant de 1 à 40 atomes de carbone qui peut avoir un substituant ; R5 représente un groupe hydrocarboné ayant de 1 à 20 atomes de carbone qui peut avoir un substituant ; et R6 et R7 représentent indépendamment un atome d'hydrogène, un groupe hydrocarboné ayant de 1 à 20 atomes de carbone qui peut avoir un substituant ou un atome de métal.
