azelate dibutyl maleate and the like triethyl citrate glycerol triacetyl ester butyl laurate and polyalkylene glycol phenyl ethers such as polyethylene glycol phenyl ether polypropylene glycol phenyl ether and the like among them particular preference is given to polyalkylene glycol phenyl ethers examples of the base as used for the neutralization of carboxyl groups of the organic polymer binder are ammonia alkanol amines and amines such as triethylamine and the like the present electrodeposition bath of cationic photosensitive resin composition may be composed of cationic group bearing e g amino onium and the like organic polymer binder ethylenically unsaturated compound s sensitizer and plasticizer and prepared by neutralizing the cationic groups e g amino groups of said organic binder with an acid and dispersing the composition into water as the amino bearing organic polymer binder use can be made of for example copolymer of amino bearing acrylate or methacrylate and at least one of the polymerizable monomers selected from acrylate ester methacrylate ester styrene butadiene acrylonitrile and the like alternatively a hydroxy bearing polymer is reacted with an isocyanate bearing unsaturated monomer and thus obtained product may be used as the organic polymer binder as the ethylenically unsaturated compound sensitizer and plasticizer reference should be made to the statements hereinbefore given in regard to the anionic photosensitive resin composition examples of acid to be used for the neutralization of amino groups of said cationic organic polymer binder are acetic acid crotonic acid itaconic acid and the like from the standpoint of adhesion to substrate flexibility of resinous coating developing property of photosensitive resin composition especially of anionic nature and other objects of this invention particularly preferred anionic.
