RESIN FINE PARTICLE FOR POWER STORAGE DEVICE UNDERLYING LAYER, INK FOR UNDERLYING LAYER FORMATION, UNDERLYING LAYER-ATTACHED COLLECTOR, POWER STORAGE DEVICE ELECTRODE, AND POWER STORAGE DEVICE

摘要

PROBLEM TO BE SOLVED: To provide resin fine particles for an underlying layer of a power storage device, which makes possible to offer an underlying layer superior in adhesion with a collector or an electrode plate layer and superior in water resistance and a power storage device superior in charge and discharge cycle characteristics.SOLUTION: The above problem is solved by a resin fine particle (A) for an underlying layer of a power storage device which is produced by emulsion polymerization of monomers including 0.1-20 wt% of at least one ethylenic unsaturated monomer selected from a group consisting of a monomer (a) having a monofunctional or polyfunctional alkoxy silyl group, a monomer (b) having a monofunctional or polyfunctional isocyanate group, a monomer (c) having a monofunctional or polyfunctional block isocyanate group, and a monomer (d) having a monofunctional or polyfunctional alkylolamide group, and 80-99.9 wt% of an ethylenic unsaturated monomer (e) other than the monomers (a) to (d).
