Abstract: A method for manufacturing a substrate having electrically conductive circuits on its surface, window-shaped films on the electrically conducive circuits and a frame-shaped film at the regions not occupied with the window-shaped films, includes the steps of:(a) coating the surface of a transparent substrate with a photoresist composition to cover the electrically conductive circuits-carrying surface of the substrate, followed by forming a photoresist film,(b) superposing a photomask on the surface of the photoresist film formed in step (a) and exposing the thus mask-superposed photoresist film to light,(c) subjecting the substrate obtained in step (b) to development,(d) subjecting the photoresist film left in step (c) to heat-treatment, second exposure to light or no treatment,(e) subjecting the substrate passed the steps (a) to electro-deposition using the electrically conductive circuits on the substrate as one electrode to form electro-deposition coating films,(f) eliminating the photoresist film having be

Abstract: A method for manufacturing a substrate useful as a color filter for LCD and having window-shaped coating films and a frame-shaped, functional coating film at the regions not occupied with the window-shaped coating films, which comprises the steps of:(a) forming a functional coating film on a transparent substrate having electrically conductive circuits on a surface thereof,(b) superposing a photomask having a predetermined pattern on the surface of the coating film formed in step (a), and exposing the thus masked coating film to light,(c) subjecting the intermediate product to developing to leave a frame-shaped coating film, and(d) subjecting the resulting substrate formed through steps (a) to (c) to electro-deposition to form electro-deposition coating films on the electrically conductive circuits, enables production of coating films of fine pattern with improved precision.

Abstract: 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.

Abstract: A process for coating an article is provided herein, which process comprises subjecting an article to a powder electrodeposition in a bath containing a water-thinnable cationic synthetic resin and a synthetic resin in the form of a fine powder, and then subjecting the thus coated material, without hardening the formed coating, to an additional electrodeposition in a bath containing an ionic synthetic resin and baking the coated article to effect cross-linking and hardening between the resins; the improvement step which is characterized in spraying hot water of more than 50.degree. C. onto the coated film after finishing the first half powder electrodeposition, but before carrying out the second half electrodeposition step.
