ABSTRACT OF THE DISCLOSURE An additive composition for use in paper- making comprises a water-soluble polymer having in aluminum chloride and an aqueous solvent. Because of formation of a kind of crosslinking structure between the water-soluble polymer molecules through the poly- aluminum chloride, the above composition exerts an effect of enhancing the paper strength when used alone and an effect of enhancing both the sizing effect and the paper strength when used together with a sizing agent. The composition further increases the paper strength when used in combination with a conventional paper-strength improver.
