Composition comprises at least a methacrylate ester monomer, adhesion promoter based on phosphate ester, polymerization accelerator comprising tertiary amine compound (I) and in combination with the radical polymerization initiator, a conjugated system having an absorption in the visible electromagnetic spectrum, to generate the color of the polymer or the cement during polymerization reaction of the monomer. Composition comprises at least a methacrylate ester monomer, adhesion promoter based on phosphate ester, polymerization accelerator comprising tertiary amine compound of formula (I) and n combination with a radical polymerization initiator, a conjugated system having an absorption in the visible electromagnetic spectrum, to generate the color of the polymer or the cement during polymerization reaction of the monomer. R3 : resonance electron-donor group comprising at least aromatic group; and R1, R2 : 1-16C, preferably 1-5C alkyl, 5-30C, preferably 5-10C aryl, 5-30C, preferably 5-10C arylalkyl or 2-15C, preferably 2-5C alkylidene.
