PURPOSE:To obtain a photosensitive resin compsn. having an excellent release property and flexibility by incorporating a specific resin salt, a water insoluble photopolymerizable unsatd. compd. and a water insoluble photoinitiator into the compsn. CONSTITUTION:This photosensitive resin compsn. is prepd. by incorporating the resin salt formed by neutralizing a linear polymer compd. obtd. by copolymerizing >=5 pts.wt. monomer expressed by formula, 10 to 30 pts.wt. vinyl monomer contg. a carboxyl group and 0 to 85 pts.wt. other vinyl monomers at ratios at which the total amt. of the respective components attains 100 pts.wt., the water insoluble photopolymerizable unsatd. compd. and the water insoluble photoinitiator into the compsn. This electrodeposition coating bath is obtd. by using the compsn. A conductive base body is immersed as an anode into the electrodeposition coating bath and is subjected to electrodeposition by energization to form an electrodeposition coating film on the conductive base body. Next, the electrodeposition coating film is irradiated in an image form with active rays, by which the exposed parts are photoset and the unexposed parts are removed by development. In the formula, R<1> is a hydrogen atom, etc.; R<2> is an alkylene group; R<3> is an alkyl group; n is an integer from 1 to 23. |
