Zusammenfassung:	To provide a cationic electro-deposition coating composition which exhibits higher corrosion resistance, and good performance, especially, even in a cycle corrosion test.SOLUTION: A cationic electro-deposition coating composition contains an aminated epoxy resin, a blocked polyisocyanate curing agent, and a polyamine polymer having an N-substituted diallylamine segment. The polyamine polymer has an N-substituted diallylamine segment represented by the following formula (1), or its acid addition salt. In the formula (1), p and q represent 0 or 1, when p is 1, q is 0, and when p is 0, q is 1; and R1 is the same or different, and represents an alkyl group which may have a hydroxyl group and has 1 to 10 carbon atoms or an aralkyl group having 7 to 10 carbon atoms.SELECTED DRAWING: None 【課題】より高い防食性、特にサイクル腐食試験でも良好な性能を示すカチオン電着塗料組成物を提供する。【解決手段】アミン化エポキシ樹脂、ブロック化ポリイソシアネート硬化剤およびＮ置換ジアリルアミンセグメントを有するポリアミン重合体を含有するカチオン電着塗料組成物を提供する。ポリアミン重合体は、下記式：TIFF2022129791000017.tif3777（式中、ｐおよびｑはいずれも０または１を示し、ｐが１の時にはｑは０で、ｐが０の時にはｑは１である。Ｒ１は、同一または異なって、水酸基を有してもよい炭素数１～１０のアルキル基または炭素数７～１０のアラルキル基を示す。）で表されるＮ置換ジアリルアミンセグメントまたはその酸付加塩を有する。【選択図】なし
