Zusammenfassung:A flame-resistant print media coating composition includes water and polyurethane particles dispersed in the water. The polyurethane particles include a polyurethane polymer having a polyurethane backbone with urethane linkage groups coupling polymerized diisocyanates and polymerized polymeric diols along the polyurethane backbone. The polyurethane polymer in this example includes aliphatic phosphonium salt capping groups.
