Claims
- 1. A polymeric binder suitable for use in an inkjet ink composition, comprising an emulsion-polymerized addition copolymer formed from a monomer mixture consisting essentially of ethylenically unsaturated monomers including from more than 4to 15 wt % based on the weight of said mixture of at least one ethylenically unsaturated carboxylic acid functional monomer, and from 0.05 to 5 wt % based on the weight of said mixture of at least one polymerizable surfactant monomer comprising hydrophobic and hydrophilic functional groups, wherein said hydrophobic functional group comprises a polymerizable group within it.
- 2. A polymeric binder as claimed in claim 1, wherein the polymerizable surfactant comprises a polymerizable group selected from (meth)acryl and (meth)allyl.
- 3. A polymeric binder as claimed in claim 2, wherein the polymerizable surfactant is selected from the group of polymerizable surfactant monomers consisting of nonylphenoxy propenyl polyethoxylated sulphate; sodium alkyl allyl sulphosuccinate; ammonium di-(tricyclo(5.2.1.0 2,6) dec-3-en-(8 or 9)oxyethyl) sulfosuccinate; and ammonium di-(tricyclo(5.2.1.0 2,6) dec-3-en-(8 or 9) sulfosuccinate.
- 4. A polymeric binder as claimed in claim 1, wherein the acid functional monomer is one or more monomers selected from the group consisting of C3 to C20 ethylenically unsaturated carboxylic acids, their basic salts, and mixtures of such monomers.
- 5. A polymeric binder as claimed in claim 1, wherein said monomer mixture comprises one or mare monomers selected from the group of monomers consisting of substituted and unsubstituted (C1 to C50) alkyl (met) acrylates, styrene and substituted styrenes, vinyl acrylates, vinyl acetates, fluoromethacrylates, acrylamide, substituted acrylamides, and methacrylamides, substituted methacrylamides.
