Abstract

L'invention concerne des objets laqués d'utilisation courante, notamment des carrosseries de véhicules, et des laques utiles pour laquer ces objets. Afin d'obtenir avec cette laque des effets nouveaux de coloration inconnus dans l'état de la technique, on mélange à la laque au moins certains pigments d'interférence en paillettes ou uniquement de tels pigments. Lorsque la laque est appliquée, ces pigments s'orientent automatiquement dans une direction à peu près parallèle à la surface de l'objet. Ces pigments sont constitués de polymères à chaînes latérales à cristaux liquides qui contiennent un composant nématique et un composant chiral. Les mésogènes des groupes latéraux sont aux moins approximativement nématiques, smectiques et/ou cholestériques. On peut ainsi générer sur l'objet laqué un effet de moirage en fonction de la direction d'incidence de la lumière et de la direction d'observation, ou des tonalités particulièrement intenses d'une brillance auparavant inconnue.
