A color filter having, on a surface of a substrate, colored coating films formed by electro-deposition using a photosensitive material and functional coating films between the gaps of the colored coating films formed by exposure to light from the back side of the substrate using a photosensitive, coating film-forming resin composition is superior in optical properties and reliability, surface-flatness, clearness in coloration and color contrast and is free from leakage of light by highly precise formation of the colored coating films and functional coating films.

Method for manufacturing color filter and liquid crystal display

A color filter having discrete color layers arrayed on a substrate and light screening coating films interlaced between the color layers and if desired seal part having no coating film thereon, with high precision is industrially advantageously manufactured by (a) forming a transparent electroconductive layer on a transparent substrate, (b) coating the transparent electroconductive layer with a positive photoresist composition to form a photoresist layer, (c) exposing the photoresist layer to light through a photomask and developing the light-exposed photoresist layer to form a circuit-form photoresist layer, (d) etching and eliminating the transparent electroconductive layer bared in the gaps between the circuit-form photoresist layer to obtain a substrate having thereon a circuit-form laminate, (e) exposing the laminate to light through a photomask and developing the light-exposed laminate to bare the transparent electroconductive layer discretely, (f) carrying out electrodeposition using a thermosetting or photosensitive resin material-containing electro-deposition bath to form colored layers on the discretely bared transparent electroconductive layers, (g) eliminating the photoresist layer remaining after the development of step (e) to obtain a substrate having discrete color layers, the gaps being bared substrate surface and bared transparent electroconductive layer, (h) coating the substrate with a light screening material-containing photosensitive resin composition to form a light screening resin layer, and (i) exposing the light screening resin layer to light from the back side and developing the substrate to eliminate the unexposed part of the light screening resin layer. The color filter is well prevented from leakage of light and clear in coloration and superior in optical properties. A liquid crystal display of high image quality is manufactured by the use of this color filter.

The present invention is for a method of forming a coating film used for filling the space between the color stripes for a color filter which is used for colorization of a liquid crystal display. In particular, the light-shielding electrodeposition coating is first formed in a transparent electric conductive circuit pattern so as to suppress the reaction of a photo-setting material against light which is to be applied to the electrodeposition coating.

A process is provided for applying an anticorrosive coating on an automobile body member. The process comprises subjecting the whole or lower portion of the body member to an electrodeposition in an aqueous bath containing (A) a cationic resinous binder and (B) a synthetic resin in the form of fine powder which is solid at room temperature but can melt at an elevated temperature, the weight ratio of (A)/(B) being 1/0.05-5. Subsequently the whole of the body member is subjected, without hardening the deposited film, to an electrodeposition in an aqueous bath containing an anionic or cationic resin. The thus treated article is washed with water and baked to effect the hardening thereof.
