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.

The present invention provides a process for forming a solder mask on an electric circuit board without any defects. The process comprises forming an electric circuit on a substrate, coating a negative type photosensitive solder resist on the obtained electric circuit board, and then exposing to light through a negative film followed by developing, characterized in that the negative type photosensitive solder resist is electrodepositable and said coating of the solder resist is conducted by electrocoating the resist on an electroconductive transfer substrate which is different from the electric circuit board and then transferring the coated film onto the electric circuit board.
