| 摘要 |
The invention relates to a photopolymerisable dental composition, by means of radiation at a wavelength greater than 390 nm, comprising a photosensitizer (E) which is a salt of a thioxanthone substituted by at least one group (G), comprising an ammonium function. Said composition has the advantage of resolving the problems of chromatic stability of finished dental products (after cross-linking). |
