polymers may also include non ionic monomers useful anionic polymers include copolymers of styrene and maleic acid and their mono esters ab block polymers wherein the a block comprises homopolymers or copolymers prepared from methyl methacrylate mma or butyl methacrylate bma and a b block comprises homopolymers or copolymers prepared from methacrylic acid particularly preferred anionic polymers are ab block polymers with an a block prepared from homopolymers or copolymers of methyl methacrylate mma and butyl methacrylate bma and a b block prepared from homopolymers or copolymers of methacrylic acid particularly preferred are ab block polymers of bma bma maa 10 5 10 and bma maa 10 10 the ink compositions may also contain other ingredients for example the surfactants may be used to alter surface tension as well as maximize penetration however as is known in the art surfactants may destabilize the pigment dispersion in addition it has been observed that the use of surfactants may cause an increase in the amount of bleed over what would be present if the surfactants had not been present accordingly the use of surfactants may tend to negate the advantages offered by the present invention however if it is otherwise desirable or necessary for a surfactant to be present it has been discovered that the adverse effects of the surfactant on bleed can be minimized or eliminated by adding additional polymer water soluble alkyltrimethylammonium salts wherein the alkyl contains from 8 16 carbon atoms such as dodecyltrimethyl ammonium chloride for example have been found to be effective in further reducing bleed when added to cationic pigmented inks preferably a c12 alkyl is used because below 12 carbons bleed is compromised and above.
