摘要:
The present invention relates to specific metal complexes of dithiolenes with perfluoroalkyl substituted imidazolidine-2-chalcogenone-4,5-dithione ligands, a process for their preparation and their use as colourless IR absorbers, for optical filters application; especially for plasma display panels, or for laser welding of plastics. The compounds may be used in compositions for inks, paints and plastics, especially in a wide variety of printing systems and are particularly well-suited for security applications.
摘要:
Described is a black dichroic dye composition comprising 2 or more dyes, wherein at least one dye, generally a red dye and optionally a yellow dye, conforms to the formula A and at least one dye, usually a blue dye, conforms to the formula B Ar1—N═N—[Ar2—N═N—]qAr3—N═N—Ar4 (B) with symbols as defined in present claims. The dye composition is well suited for combination with liquid crystal material for use, inter alia, as polarizing film and/or in liquid crystal displays, showing, inter alia, high dichroic ratio and excellent compatibility with the LC material.
