<P>PROBLEM TO BE SOLVED: To provide a composition for a nonaqueous secondary battery electrode which is excellent in adhesion with a current collector or an electrode and capable of providing a nonaqueous secondary battery retaining high discharge capacity even after repetition of charge-discharge cycles or even under high-temperature environment due to heat generation, to provide the nonaqueous secondary battery electrode which has reduced influence on an electrode active material and achieves charge-discharge cycle characteristics and high capacity by securing current collection property and improving the utilization rate, and to provide the nonaqueous secondary battery using the same electrode. <P>SOLUTION: The composition for the nonaqueous secondary battery electrode comprises an active material and an urethane resin particulate water dispersion. The urethane resin water particulate water dispersion comprises polyisocyanate (A), polyol (B) having a molecular weight of 500 to 4000, polyol (C) having a molecular weight of less than 500, and diol (D) having a carboxyl group. <P>COPYRIGHT: (C)2013,JPO&INPIT |
