摘要:
The present invention provides dyes of formula I-XXXIV, described in detail below and dichroic light polarizers based on the dyes. In the dichroic light polarizers of this invention, the dye molecules are aggregated into particles oriented in a predetermined direction on a surface of a substrate to enable the dye to polarize light transmitted through the dye.

Verfahren zur Herstellung von Pigmenten der Anthanthronreihe der Formel worin R, und R 2 Chlor-, Brom- oder todatome oder Alkoxy-C 1 -C 4 -Gruppen bedeuten, mit wertvollen Eigenschaften, dadurch gekennzeichnet, daß man die Anthanthrone der genannten Formel in Form des Rohpigments zunächst in wäßrig-alkalischem Medium bei einem pH-wert > 10 in die Leukoform überführt, diese durch Zugabe anorganischer oder organischer Säuren abscheidet, die wäßrige Suspension der Leukoform zu den Anthanthronen reoxydiert und die so erhaltenen feinteiligen Präpigmente der genannten Formel einem Lösungsmittelfinish unterwirft.
摘要:
The present invention provides anthraquinonyl and anthronyl dyes and dichroic light polarizers based on the dyes. The dichroic light polarizer includes two separate embodiments. In the first embodiment, the dye molecules are aggregated into particles oriented in a predetermined direction on the surface of a substrate to enable the dye to polarize light transmitted through the dye. In the other embodiment, the dye molecules are molecularly oriented in a non-periodic arrangement of different polarizing elements on the surface of a substrate. Each of the polarizing elements has a differing orientation of the polarization vector in the substrate plane and/or a different color. The dichroic light polarizer may contain one or more additional dye layers and may have a transparent layer intermediate between the dye layers.

The present invention provides a dichroic light polarizer which includes a molecularly oriented layer of an organic dye on a surface of a substrate. The layer has a non-periodic arrangement of different polarizing elements. Each of the polarizing elements have differing orientations of the polarization vector in the substrate plane and/or differing colors. The dichroic light polarizer may contain one or more additional dye layers and may have a transparent layer intermediate the dye layers.
