摘要：
A method of preparing an aqueous dispersion comprising silver particles of mean diameter from 0.5 to 25 nm by weight and an aqueous carrier liquid, including the steps of i) providing a mixture comprising at least one silver salt, aqueous carrier liquid and a stabiliser for the particles ii) contacting the mixture with a non-ionic or covalent reducing agent to form a reaction mixture iii) causing the at least one silver salt to react with the reducing agent to form a dispersion comprising silver particles and acid wherein step iii) is partly or completely performed in the presence of anion exchange resin whereby the acid is exchanged for a hydroxide ion from the resin and/or is sorbed by the resin.
摘要（中）：
一种制备包含平均直径为0.5至25nm的银颗粒和水性载体液体的水性分散体的方法，包括以下步骤：i）提供包含至少一种银盐，含水载体液体和稳定剂的混合物， 颗粒ii）使混合物与非离子或共价还原剂接触以形成反应混合物; iii）使至少一种银盐与还原剂反应形成包含银颗粒和酸的分散体，其中步骤iii）部分 或在阴离子交换树脂的存在下完全进行，由此将酸从树脂中更换为氢氧根离子和/或被树脂吸附。
