COMPOSITIONS AND METHOD FOR PREVENTING THE STAINING OF NITROCELLULOSE FINISHED SHOE UPPERS ATTACHED TO POLYURETHANE SHOE SOLES

摘要

To prevent the staining of a nitrocellulose coated shoe upper by a polyurethane shoe sole prepared from a mixture comprising a polyisocyanate, a polyol, a chain extender, a tertiary amine catalyst, a surfactant and water, an effective amount of a reactive organic halogen compound, preferably a halogenated fire retardant, is added.
