Abstract:
1. A process for the preparation of a semi-finished display panel, which process comprises the steps of: a) coating a layer of a thermoplastic, thermoset or precursor thereof on a temporary substrate layer followed by embossing the coated layer with a male mold or imagewise exposing a layer of a radiation curable composition coated on a temporary substrate layer followed by removing unexposed areas, to form an array of microcups; b) filling the microcups with a charged pigment dispersion in a dielectric solvent or solvent mixture; c) top-sealing the microcups with a sealing composition having a specific gravity lower than that of said dielectric solvent or solvent mixture; and d) applying a conductor layer or a permanent substrate layer onto the top-sealed microcups.
