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 can cause a non-aqueous secondary battery to display excellent cycle characteristics. The composition for a non-aqueous secondary battery functional layer contains organic particles and a solvent. The organic particles include a polyfunctional ethylenically unsaturated monomer unit in a proportion of not less than 55 mass % and not more than 90 mass %, and have a volume-average particle diameter of not less than 50 nm and not more than 370 nm.
