  [EN] The invention discloses a multilayer of cholesteric liquid crystal polymer (CLCP), wherein at least two layers of CLCP differing in at least one optical property are arranged on top of each other, characterized in that said at least two layers are chemically inter-layer cross-linked through the polymer network, such as to form a mechanically unique solid body which can be comminuted to pigment without deterioration of its inner structure, and which has an abrupt change of cholesteric liquid crystal pitch at the interface between said at least two layers of cholesteric liquid crystal polymer. Corresponding pigments, coating compositions and there use in security and decorative printing and coating applications are disclosed as well.
  [FR] L'invention concerne une multicouche de polymère à cristaux liquides cholestériques (CLCP), au moins deux couches de CLCP différant au niveau d'au moins une propriété optique étant disposées l'une sur l'autre, caractérisée en ce que lesdites deux couches ou plus sont réticulées chimiquement entre les couches via le réseau polymère, de manière à former un corps solide mécanique unique qui peut être broyé en pigment sans détériorer sa structure interne et qui présente un changement abrupt de son pas de cristaux liquides cholestériques à l'interface entre lesdites deux couches ou plus de polymères à cristaux liquides polymériques. L'invention concerne également les pigments correspondants, des compositions de revêtements et leur utilisation pour des applications d'impression de sécurité, d'impression décorative et de revêtements.
