Abstract
Provided is a composition for a non-aqueous secondary battery functional layer with which it is possible to form a functional layer that has excellent heat shrinkage resistance and adhesiveness after immersion in electrolyte solution and that can cause a non-aqueous secondary battery to display excellent cycle characteristics. The composition for a functional layer contains first organic particles, second organic particles, and a solvent. The first organic particles include a polyfunctional ethylenically unsaturated monomer unit in a proportion of not less than 20 mass % and not more than 90 mass %. The second organic particles include a nitrile group-containing monomer unit in a proportion of not less than 20 mass % and not more than 80 mass % and a cross-linkable monomer unit in a proportion of not less than 0.1 mass % and not more than 10 mass %.
