ABSTRACT:
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)nwherein 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 2 and 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.
