Title (EN) VARNISH COMPOSITION AND LIQUID-CRYSTAL DISPLAY ELEMENT
(FR) COMPOSITION DE VERNIS ET ELEMENT D'AFFICHAGE A CRISTAUX LIQUIDES
Abstract:
(EN) A varnish composition which comprises a solvent and a polymer ingredient comprising a polyamic acid (B) (having residues which are derived from a tetracarboxylic acid and a diamine respectively and which are residues having no pendant groups or residues having a pendant C1-2 alkyl group or are residues having a composition comprising a mixture of these), a polyamic acid (A) (having residues which are derived from a tetracarboxylic acid and a diamine respectively and at least either of which is a residue having a pendant C3+ alkyl group or is a residue having a composition containing that residue), and a soluble polyimide, and in which the proportion of the polyamic acid (A) to the soluble polyimide is 1/99 to 99/1 by weight, the sum of the polyamic acid (A) and the soluble polyimide accounts for 1 to 80 wt.% of the polymer ingredient, the polyamic acid (B) accounts for 99 to 20 wt.% of the polymer ingredient, and the proportion of the polymer ingredient in the whole varnish composition is 0.1 to 40 wt.%. Also provided is a liquid-crystal display element having an alignment film formed from this varnish composition.
(FR) L'invention concerne une composition de vernis comprenant un solvant et un ingrédient polymère composé d'un acide polyamique (B) (possédant des résidus respectivement dérivés d'un acide tétracarboxylique et d'une diamine, ces résidus ne comportent soit pas de groupe pendant, soit un groupe pendant C1-2 alkyle, ou sont composés d'un mélange des deux), d'un acide polyamique (A) (possédant des résidus respectivement dérivés d'un acide tétracarboxylique et d'une diamine, au moins un de ces résidus possédant un groupe pendant C3+ alkyle ou présentant une composition contenant ce résidu), et d'un polyimide soluble. Dans cet ingrédient polymère, la proportion de l'acide polyamique (A) par rapport au polyimide soluble est comprise entre 1/99 et 99/1 en poids, la somme de l'acide polyamique (A) et du polyimide soluble représente entre 1 et 80 % en poids de l'ingrédient polymère, l'acide polyamique (B) représente entre 99 et 20 % en poids de l'ingrédient polymère, et la proportion de l'ingrédient polymère dans la composition totale du vernis est comprise entre 0,1 et 40 % en poids. L'invention concerne également un élément d'affichage à cristaux liquides comportant un film d'alignement obtenu à partir de cette composition de vernis.
