Pigments for Non-Aqueous Inks and Coatings

A complex represented by Formula (1):

• [Q[SO3−]mMnk+]pDqEr (1)
• wherein:
• Q is an organic pigment moiety;
• D is independently [R1R2N(CH2CH(CH3)O)x(CH2CH2O)yR4];
• E is independently [R1R2R3N(CH2CH(CH3)O)x(CH2CH2O)yR4]+;
• x and y independently range from 0 through 300, provided that for D and E selected independently, the sum of x+y is at least 3;
• M is independently selected from the group consisting of Al, Fe, Ca, Mg, Sr, Ba, Mn, Cu, Ni, Cd, Co, Zn, Cr, Ti, Zr, and NR1R2R3R4;
• R1, R2, and R3 are independently selected from the group consisting of H, alkyl, aryl, alkaryl, poly-(oxyalkylene), provided that for E, if both R1 and R2 are H, then R3 is H;
• R4 is independently selected from the group consisting of H, alkyl, aryl, and alkaryl;
• k is an integer of from 1 through 4;
• m ranges from 0.1 through 6;
• n ranges from 0.1 through 6;
• p ranges from 1 through 99;
• q ranges from 0 through 99;
• r ranges from 0 through 99;
• and
• (q+r) ranges from 0.01 through 99.
