摘要： An erasable ink composition contains a dispersion of solid particles of water-insoluble polymer-encapsulated colorant obtained from the emulsion polymerization of at least one emulsion-polymerizable monomer in the presence of solid colorant particles. The ink is intended for use in any of a variety of marking instruments, in particular, a ball-point pen.

摘要： Novel, improved ink compositions are aqueous-based, shock-resistant, shear-thinning inks for writing instruments having a shear index greater than 0.6. The inks are a substantially uniform dispersion including colorant(s), a water dispersible, polymeric shear-thinning material selected from the group consisting of welan gum, rhamsan gum and combinations thereof, and a substantially water-soluble polymeric viscosity modifier in a polar solvent system. While the ink compositions have a high viscosity at low shear rates, they undergo shear-thinning and are readily flowable in response to shear rates produced in writing to provide a writing ink having an especially desirable combination of performance characteristics.
摘要翻译： 新颖的改进的油墨组合物是用于书写具有大于0.6的剪切指数的仪器的基于水的，抗冲击的剪切稀释油墨。 油墨是基本均匀的分散体，包括着色剂，水分散性，聚合物剪切稀化材料，其选自韦兰胶，罗姆沙胶及其组合，以及极性溶剂中基本上水溶性的聚合粘度改进剂 系统。 虽然油墨组合物在低剪切速率下具有高粘度，但它们经历剪切变稀，并且响应于书面产生的剪切速率容易流动，以提供具有特别期望的性能特性组合的书写油墨。
