<p><P>PROBLEM TO BE SOLVED: To provide a curing agent used for an epoxy resin which can obtain a cured produce having excellent water solubility and further having more excellent coating film strength and corrosion resistance while maintaining emulsion stability to an epoxy resin. <P>SOLUTION: The amine-based curing agent is composed of the aromatic diamine adduct body of an epoxy resin having a polyethylene glycol monoalkyl ether residue at side chains obtained by reacting an epoxy resin (I) having a polyethylene glycol monoalkyl ether residue at side chains which is obtained by reacting a compound having at least two or more carboxy groups in one molecule and a polyethylene glycol monoalkyl ether residue which is obtained by esterification-reacting polyethylene glycol monoalkyl ether with an acid anhydride derived from polycarboxylic acid having three or four carboxy groups in one molecule with an epoxy resin having two or more epoxy groups in one molecule with aromatic diamine (II). <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
