Process for broadening cholesteric reflection bands of photopolymerizable cholesteric liquid crystals, and optical elements produced by this process. The invention relates to a process for broadening the cholesteric reflection bands of photopolymerizable cholesteric liquid crystals, which comprises the following process steps: 1) partial polymerization of a layer containing photopolymerizable cholesteric liquid crystals by exposure to actinic light for a defined brief period at a defined temperature, 2) observance of a defined waiting time without exposure (dark phase) at a defined temperature, 3) fixing of the resultant layer by exposure to actinic light at a defined temperature.

Procédé pour élargir les bandes de réflexion de cristaux cholestériques liquides photopolymérisables; éléments optiques obtenus grâce à ce procédé. L'invention porte sur un procédé pour élargir les bandes de réflexion de cristaux cholestériques liquides photopolymérisables, comprenant les étapes suivantes : 1) polymérisation partielle d'une couche renfermant des cristaux cholestériques liquides photopolymérisables, par exposition à la lumière actinique pendant une brève période et à une température données; 2) non-exposition pendant une période d'attente (phase d'obscurité) et à une température données; 3) fixation de la couche résultante, par exposition à la lumière actinique à une température donnée.
