PURPOSE:A flameproofing agent composition, obtained by incorporating guanidine sulfamate with guanidine methylolsulfamate and ammonium sulfamate, etc. in a specific proportion, and capable of keeping the flameproofing effect for a long period without discoloring paper nor deteriorating strength thereof. CONSTITUTION:A flameproofing agent composition obtained by incorporating (A) 61-85wt% guanidine sulfamate with (B) 10-39wt% guanidine methylolsulfamate, (C) 2-19wt% ammonium sulfamate and (D) <=20wt% organic nitrogen compound selected from the group consisting of dicyandiamide, methyloldicyandiamide and hexamethylenetetramine. The amount of the above-mentioned composition to be applied to paper is suitably 3-35wt% active constituents except solvents, e.g. water.
