SLURRY COMPOSITION FOR NON-AQUEOUS SECONDARY BATTERY HEAT-RESISTANT LAYER, HEAT-RESISTANT LAYER FOR NON-AQUEOUS SECONDARY BATTERY, AND NON-AQUEOUS SECONDARY BATTERY

Provided is a slurry composition for a non-aqueous secondary battery heat-resistant layer that has excellent dispersion stability and coatability and can form a heat-resistant layer for a non-aqueous secondary battery having both excellent heat shrinkage resistance and reduced residual water content. The slurry composition contains a water-soluble polymer, non-conductive organic particles, and water. The water-soluble polymer includes an amide group-containing monomer unit, an acid group-containing monomer unit, and a hydroxyl group-containing monomer unit. The proportional content of the amide group-containing monomer unit in the water-soluble polymer is not less than 63 mass % and not more than 98 mass %, and the proportional content of the acid group-containing monomer unit in the water-soluble polymer is not less than 1 mass % and not more than 20 mass %. The non-conductive organic particles include a cross-linkable monomer unit with a proportional content of not less than 20 mass % and not more than 95 mass %.
