PROBLEM TO BE SOLVED: To provide a composition for flameproofing, enabling an active ingredient to be present sufficiently at the vicinity of the surface even if the composition for the flameproofing is applied on the surface of a base material into the inside of which the composition easily infiltrates, hardly migrating to a neighboring layer even if the composition is laminated, heated and pressurized, and capable of forming a sufficient carbonized layer; to provide a sheet for the flameproofing by utilizing the composition for the flameproofing; and to provide a flame-retardant decorative sheet. SOLUTION: The composition for the flameproofing is obtained by compounding aluminum phosphite, a water-soluble binder and a scaly inorganic material. The aluminum phosphite itself foams and forms a foamed layer. The scaly inorganic material functions as an obstacle for blocking the infiltration into the inside of the base material or the migration to the neighboring layer of a flowable component in the composition for the flameproofing containing the aluminum phosphite as the main component. A region having an extremely high abundance ratio of the composition for the flameproofing can be formed by the composition for the flameproofing, and the sufficiently foamed and carbonized layer can be formed.
