Summary: | Provided is a slurry composition for a non-aqueous secondary battery heat-resistant layer that has excellent dispersion stability and coatability and that can form a heat-resistant layer for a non-aqueous secondary battery having excellent heat shrinkage resistance. The slurry composition contains a water-soluble polymer, non-conductive particles, and water. The water-soluble polymer includes an amide group-containing monomer unit and an acid group-containing monomer unit, with the proportional content of the amide group-containing monomer unit being 60 mass % to 98 mass % and the proportional content of the acid group-containing monomer unit being 1 mass % to 25 mass % in the water-soluble polymer. The slurry composition has a pH of 7.0 to 10.0, a viscosity of 10 mPa·s to 300 mPa·s, and a contact angle with a polyethylene substrate of 20° to 50°. |
