The invention pertains to a coating composition comprising a first compound comprising at least one bicyclo- or spiro-orthoester group and a second compound comprising at least two hydroxyl-reactive groups. The invention also comprises a process for curing the present coating composition. More particularly, the latent hydroxyl groups of the bicyclo- or spiro-orthoester groups have to be deblocked and reacted with the hydroxyl-reactive groups of the second compound if the present coating composition is to be cured. Further, a process for making bicyclo-orthoester compounds from the corresponding oxetane compound is described, as are polymers comprising at least one bicyclo- or spiro-orthoester group. L'invention concerne une composition de revêtement comprenant un premier composé comportant au moins un groupe bicyclo- ou spiro-orthoester et un deuxième composé comprenant au moins deux groupes réactifs à l'hydroxyle. L'invention concerne également un procédé pour durcir la composition de revêtement. Plus particulièrement, les groupes hydroxyles latents des groupes bicyclo- ou spiro-orthoester doivent être déséquencés pour réagir avec les groupes réactifs à l'hydroxyle du deuxième composé lorsque la composition de revêtement doit être durcie. En outre, l'invention traite d'un procédé de fabrication de composés bicyclo-orthoester à partir du composé d'oxétane correspondant, ainsi que des polymères comprenant au moins un groupe bicyclo- ou spiro-orthoester.
