A novel transfer material is disclosed. The transfer material comprises, at least, a support, and, thereon, an optically uniaxial or biaxial anisotropic layer and a photosensitive polymer layer. A novel process for producing a liquid crystal cell substrate is also disclosed. The process comprises, at least, [1] laminating a transfer material as set forth in any one of claims 1 to 11 on a substrate; [2] removing the support from the transfer material laminated on the substrate; and [3] exposing the photosensitive polymer layer disposed on the substrate to light. La présente invention concerne une nouvelle matière de transfert comprenant au moins un support sur lequel se trouvent une couche anisotrope optiquement uniaxiale ou biaxiale et une couche polymère photosensible. Cette invention concerne également un nouveau procédé pour produire un substrat de cellules à cristaux liquides. Ce procédé consiste au moins (1) à stratifier sur un substrat une matière de transfert du type indiqué dans les revendications 1 à 11, (2) à retirer le support de la matière de transfert stratifiée sur le substrat, puis (3) à exposer à la lumière la couche polymère photosensible placée sur le substrat.
