Ozone Stable Ink-Jet Inks

An ozone stable magenta ink comprising:

• an ozone stable magenta dye;
• and
• a liquid vehicle including a fluorocarbon surfactant formed at least in part from a polymer comprising Formula 1:
• Where R1=H, OH, or CH3;
• and R2=O(CH2)m-(CF2)n-CF3 with m=1-3 and n=0-3, wherein the fluorocarbon surfactant is represented by Formula 3:
• wherein
• Q1 and Q2 are independently selected from the group consisting of H, SO3−W+, COO−W+, and COOH and wherein W is selected from the group consisting of NH4, Li, Na, and K;
• R4 and R2, are independently selected from the group consisting of H and OH;
• R1, and R5 are independently selected from the group consisting of O(CH2)m—(CF2)n—CF3 wherein m=1-3 and n=0-3;
• R3 is selected from the group consisting of (CH2)L and
• L=1-4;
• x=1-10;
• y=1-30;
• and z=1-10.

An ink set comprising

• an ozone stable cyan ink including an ozone stable cyan dye having the following structure
• Formula 4
• Wherein M represents a hydrogen atom, a metal atom or an oxide, hydroxide or halide thereof;
• Pc represents a (k+l)-valent phthalocyanine nucleus represented by Formula 4;
• X represents both X1 and X2, with t representing a value of 0<t≦2;
• X1 and X2 each independently represents a substituent selected from the group consisting of —SO—R1, —SO2—R1 and —SO2NR2R3 and at least one substituent represented by X1 and at least one substituent represented by X2 are present in respective rings of four benzene rings (A, B, C and D in Formula 4 of the phthalocyanine nucleus, provided that X1 and X2 are not the same and at least one of X1 and X2 has an ionic hydrophilic group as a substituent;
• R1 represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group or a substituted or unsubstituted heterocyclic group;
• R2 represents a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group or a substituted or unsubstituted heterocyclic group;
• R3 represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group or a substituted or unsubstituted heterocyclic group;
• k and l represent an integer of 0<k<8 and an integer of 0<l<8, provided that k and/or l each independently represents a number satisfying 4≦k+l≦8.
