    • Pigment compositions and methods are provided comprising coupling agents. In various embodiments, a pigment is provided comprising titanium dioxide and a coupling agent having the formula: (R′O)(q-n)M(XRm)n wherein M is Ti, Zr, Sn, or Al; X is —CO2, ═PO2, —PO2(OH), ═PO2PO2(OH), or —SO3; m is 1 or 2; n is 1, 2, or 3 and q is 4 when M is Ti, Zr or Sn,or n is 1 or 2and q is 3 when M is Al; R′ is a substituted or unsubstituted alkyl, alkynyl, alkydiyl, alkyleno, alkanyl, alkenyl, alkoxy, aryl, arylalkyl, arylaryl, aryldiyl, or aryleno; and R is a substituted or unsubstituted alkyl, alkynyl, alkydiyl, alkyleno, alkanyl, alkenyl, alkoxy, aryl, arylalkyl, arylaryl, aryldiyl, or aryleno, wherein R comprises a carbon chain of 2 to 30 carbon atoms. The pigment compositions have improved lacing resistance, dispersibility, stability or combinations thereof.
    • 提供了包含偶联剂的颜料组合物和方法。 在各种实施方案中,提供了包含二氧化钛和具有下式的偶联剂的颜料:(R'O)(qn)M(XR m)n 其中M是Ti,Zr,Sn或Al; X是-CO 2,-PO 2,-PO 2(OH),-PO 2 PO 3, (OH)或-SO 3 N; m为1或2; 当M为Ti,Zr或Sn时,n为1,2或3,q为4,当M为Al时,n为1或2,q为3; 烷基,烷基,烷基,烯基,烷氧基,芳基,芳基烷基,芳基芳基,芳基二芳基或芳烯基; R'是取代或未取代的烷基,炔基, 烷基,烷基,烯基,烷氧基,芳基,芳烷基,芳基芳基,芳基二基或芳烯基,其中R包含2至30个碳原子的碳链。 颜料组合物具有改善的耐拉链性,分散性,稳定性或其组合。
