ABSTRACT:
This invention relates to aqueous ammoniacal combinations of benzenephosphonic acid/melamine salts as flame-retardants and a polymeric chlorine-containing film-forming latex as a carrier for the flame-retardants, for the post-treatment of flammable flexible polyurethane foamed plastics to provide products that are self-quenching and substantially resistant to both flame-initiation and flame-propagation after free flame exposures.
