Abstract: The present invention provides a method of forming a multilayer coating film comprising the step (I) of coating an article to be coated with an electrodeposition coating containing two resin components incompatible with each other followed by curing by heating to form an electrodeposited coating film, the step (II) of applying a water-borne intermediate coating onto the electrodeposited coating film to form an uncured intermediate coating film, the step (III) of applying a water-borne base coating onto the intermediate coating film to form an uncured base coating film, the step (IV) of applying a clear coating onto the base coating film to form an uncured clear coating film and the step (V) of curing the intermediate coating film, the base coating film and the clear coating film simultaneously by heating to thereby obtain a multilayer coating film.

Abstract: The present invention is to provide a method of forming a multilayer coating film by which the multilayer coating film comparable in shock resistance, in particular chipping resistance, to the conventional three-coat films can be formed in the three-wet one-bake coating system which is intended for coating process curtailment, cost reduction and environmental impact reduction.

Abstract: A video camera having an image tube and a detector for detecting the operation state of the image tube. The light intensity from an object to the image tube is controlled in accordance with the output signal from said detector.
