Disclosed is an anti-bacterial aqueous ink composition comprising water soluble sodio-sulfonated polyester. The present invention relates to a composite including: a sodium sulfonated polyester matrix of which the sodium sulfonated polyester has a degree of sulfonation of at least about 3.5 mol percent; and a plurality of silver nanoparticles which are dispersed within the matrix. In addition, the present invention relates to an aqueous ink composition including: water; an optional co-solvent; an optional colorant; and a composite comprising a sodium sulfonated polyester matrix of which the sodium sulfonated polyester has a degree of sulfonation of at least about 3.5 mol percent, and a plurality of silver nanoparticles which are dispersed within the matrix. A method includes a step of heating a sodium sulfonated polyester resin in water, wherein the sodium sulfonated polyester has a degree of sulfonation of at least about 3.5 mol percent; a step of adding a silver (I) ion solution to the heated resin in water to form a mixture; a step of optionally adding a reducing agent to the mixture; and a step of forming an emulsion of composite particles comprising a sodium sulfonated polyester matrix and a plurality of silver nanoparticles disposed within the sodium sulfonated polyester matrix. 본 발명은 설폰산나트륨화 폴리에스테르 매트릭스로서, 상기 설폰산나트륨화 폴리에스테르는 적어도 약 3.5 몰%의 설폰화도를 갖는 매트릭스; 및 상기 매트릭스 내에 분산된 다수의 은 나노 입자를 포함하는 복합체에 대해 기재한다. 본 발명은 또한 물; 선택적인 공-용매; 선택적인 착색제; 및 설폰산나트륨화 폴리에스테르 매트릭스로서 상기 설폰산나트륨화 폴리에스테르가 적어도 약 3.5 몰%의 설폰화도를 갖는 매트릭스와 상기 매트릭스 내에 분산된 다수의 은 나노 입자를 포함하는 복합체;를 포함하는 수성 잉크 조성물에 대해 기재한다. 본 발명은 또한 설폰산나트륨화 폴리에스테르 수지로서, 상기 설폰산나트륨화 폴리에스테르가 적어도 약 3.5 몰%의 설폰화도를 갖는 수지를 물에서 가열하는 단계; 물에서 상기 가열된 수지에 은 (I) 이온 용액을 첨가하여 혼합물을 형성하는 단계; 선택적으로, 환원제를 상기 혼합물에 첨가하는 단계; 및 설폰산나트륨화 폴리에스테르 매트릭스 및 상기 설폰산나트륨화 폴리에스테르 매트릭스 내에 배치된 다수의 은 나노입자를 포함하는 복합체 입자의 에멀젼을 형성하는 단계를 포함하는 방법에 대해서도 기재한다.
