Abstract

Abstract The first embodiment of the present invention is a process for producing a multicolor display comprising the following steps (a) a transfer panel which has thereon electroconductive layers insulated with each other is immersed in an electrodeposition bath, in which a voltage is applied to one or more of said electroconductive layers to be colored with a same color to form the color layer thereon, (b) said step (a) is repeated with the other colors to form a multicolor layer, and (c) said multicolor layer is transferred onto a transparent substrate. The second embodiment of the present invention is an improved process of the first embodiment, wherein both the multicolor layer and the electroconductive layer are transferred onto the transparent substrate.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 91 words
A process for producing a multicolor display composed of a transparent substrate and multicolor layers thereon, consisting essentially of the following steps: (a) immersing a transfer panel which has thereon electroconductive layers, insulated from each other, in an electrodeposition bath in which a voltage is applied to one or more of said electroconductive layers to be colored with a same color to form the color layer thereon, (b) repeating said step (a) with the other colors to form a multicolor layer, and (c) transferring said multicolor layer onto a transparent substrate.
Claim 2
Dependent Claim 91 words
A process for producing a multicolor display composed of a transparent substrate and multicolor layers thereon, consisting essentially of the following steps: (a) immersing a transfer panel which has thereon electroconductive layers, insulated from each other, in an electrodeposition bath in which a voltage is applied to one or more of said electroconductive layers to be colored with a same color to form the color layer thereon, (b) repeating said step (a) with the other colors to form a multicolor layer, and (c) transferring said multicolor layer onto a transparent substrate.
Claim 3
Dependent Claim 92 words
A process for producing a multicolor display composed of a transparent substrate and multicolor layers on said transparent substrate and electroconductive layers on said multicolor layers, consisting essentially of the following steps: (a) forming electroconductive layers insulated, from each other, on a transfer panel, (b) applying a voltage to one or more of said electroconductive layers to be colored with a same color to form the color layer, (c) repeating said step (b) to form a multicolor layer, and (d) transferring said multicolor layer and said electroconductive layer onto a transparent substrate.
Claim 4
Dependent Claim 92 words
A process for producing a multicolor display composed of a transparent substrate and multicolor layers on said transparent substrate and electroconductive layers on said multicolor layers, consisting essentially of the following steps: (a) forming electroconductive layers insulated, from each other, on a transfer panel, (b) applying a voltage to one or more of said electroconductive layers to be colored with a same color to form the color layer, (c) repeating said step (b) to form a multicolor layer, and (d) transferring said multicolor layer and said electroconductive layer onto a transparent substrate.
Claim 5
Dependent Claim 20 words
The process according to claim 2 wherein a release layer is formed between the transfer panel and the electroconductive layers.
Claim 6
Dependent Claim 12 words
The process according to claim 2 wherein said electroconductive layers are transparent.
