An emulsion-polymerized addition copolymer formed from a monomer mixture
comprising ethylenically unsaturated monomers including from more than 4
to 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, is useful as a binder in an ink jet ink
having improved print quality.
Um copolymer emulsion-polimerizado da adição deu forma de uma mistura do monomer que compreende os monomers ethylenically unsaturated que incluem de mais de 4 a 15 pesos % baseado no peso de mistura dita ao menos de um monomer funcional ethylenically unsaturated do ácido carboxylic, e 0.05 a 5 pesos % baseado no peso de mistura dita ao menos de um compreender polymerizable do monomer do surfactant hydrophobic e os grupos funcionais hydrophilic, wherein o grupo funcional hydrophobic dito compreende um grupo polymerizable dentro dele, são úteis como uma pasta em uma tinta do jato da tinta que melhora a qualidade de cópia.
