This invention is aimed at a family of masked isocyanates, advantageously masked di-isocyanate, and preferably masked poly-isocyanate. This isocyanate is defined in that it carries at least one masked isocyanate function obtainable through the action on an isocyanate of an oxime in which the carbon of the oxime function is the carrier of at least one electron-attracting function. Applications: organic synthesis.
