There is disclosed novel colorless ferric di-alkylphosphates of the general formula Fe[OOP(OR).sub.2 ].sub.3.X or Fe[OOP(OR).sub.2 ].sub.3 in which each R is independently a branched chain alkyl group and X is an anion selected from F.sup.-, PF.sub.6.sup.-, BF.sub.4.sup.-, Ph.sub.4 B.sup.-, CH.sub.3 COO.sup.-, C.sub.2 H.sub.5 COO.sup.-, C.sub.14 H.sub.29 SO.sub.4.sup.-. These compounds react with chelates to give intense and dark colored results and find utility in thermographic materials.
本发明公开了一种新的无色铁二烷基磷酸盐,其一般化学式为Fe[OOP(OR).sub.2 ].sub.3.X或Fe[OOP(OR).sub.2 ].sub.3,其中每个R独立地是支链烷基,X是从F.sup.-、PF.sub.6.sup.-、BF.sub.4.sup.-、Ph.sub.4 B.sup.-、CH.sub.3 COO.sup.-、C.sub.2 H.sub.5 COO.sup.-、C.sub.14 H.sub.29 SO.sub.4.sup.-中选择的阴离子。这些化合物与螯合剂反应产生强烈和深色的结果,并在热成像材料中发挥作用。
