Latest Patents
Choung Lai's latest patents include innovative processes for producing ink toner particles. The first patent describes a method for creating a colored toner with a textured surface. This process involves forming a polymer composition that includes at least one polymer and a colorant, where the polymer has a softening temperature ranging from about 60°C to about 160°C. The method also includes forming an aqueous mineral suspension of at least one multivalent metal phosphate and combining it with the polymer composition to create dispersed particles. The dispersion is then heated and cooled to recover the particles.
The second patent focuses on the production of toner for printing applications. This process also begins with a polymer composition and involves forming an aqueous mineral suspension of multivalent metal phosphate. The method emphasizes controlling the growth of the phosphate through the use of crystal growth inhibitors, ensuring the pH of the suspension is maintained between 5.5 and 14. The polymer composition is then added to the suspension under agitation to form a solid portion of dispersed particles.
