Fire retardant laminates including a textile layer, a protective layer, and a fire retardant are provided. The protective layer includes a porous membrane and a coating layer. The porous membrane is positioned between the textile layer and the coating layer. The fire retardant includes one or more phosphonate esters of the general formula: where n=0 or 1, Rand Rare C-Calkyl, Ris H or C-Calkyl, and Ris a linear or branched alkyl. At least a portion of the phosphonate ester in the fire retardant laminate resides in the coating layer. The fire retardant laminates are suitable for use in protective garments that provide full flammability and burn protection, even after exposure to flammable materials such as petroleum, oils, and lubricants. A method of rendering the fire retardant laminate fire retardant is also provided.
