ABSTRACT An aqueous composition comprising an insoluble ammonium polyphosphate, a surfactant and a heat curable resin, which may also contain a soluble ammonium polyphosphate and/or a carbamic acid derivative, forms a shearable paste which, when applied to the back of a fabric and heat cured, flame retards the fabric without exuding to the front face and causing resin and/or salt marks. |
