    • A fixer fluid having reduced kogation. The fixer fluid includes at least one phosphate ester surfactant and at least one cationic polymer, wherein the fixer fluid is formulated so that the at least one phosphate ester surfactant does not precipitate with the at least one cationic polymer. The at least one phosphate ester surfactant may be an anionic phosphate ester surfactant or an amphoteric phosphate ester surfactant. If the at least one phosphate ester surfactant is an anionic phosphate ester surfactant, it may have greater than or equal to approximately 2 moles of ethylene oxide per mole of the phosphate ester surfactant. The present invention also relates to an inkjet ink having reduced kogation and a method of producing a fixer fluid having reduced kogation.
    • 定影液具有减少的结垢。 定影液包括至少一种磷酸酯表面活性剂和至少一种阳离子聚合物,其中定影液被配制成使得至少一种磷酸酯表面活性剂不与至少一种阳离子聚合物一起沉淀。 所述至少一种磷酸酯表面活性剂可以是阴离子磷酸酯表面活性剂或两性磷酸酯表面活性剂。 如果至少一种磷酸酯表面活性剂是阴离子磷酸酯表面活性剂,则每摩尔磷酸酯表面活性剂可具有大于或等于约2摩尔环氧乙烷。 本发明还涉及一种具有减少的结垢的喷墨油墨和一种生产具有减少的结垢的定影液的方法。
