Latest Patents
Chung's latest patents focus on innovative recording materials. One patent describes a recording material that includes a support with at least one colored surface and a layer of polymeric material. This layer consists of polymeric particles with a core/shell structure. The particles are designed to have either an outermost polymer shell with a calculated Tg ranging from 40° C. to 80° C., or an inner polymer shell with a Tg from 40° C. to 130° C. and an outer polymer shell with a Tg from −55° C. to 50° C. The outer polymer shell's Tg is lower than that of the inner shell, and the particles contain at least one void that provides opacity to the layer. The colored surface is designed to have sufficient color density to contrast visibly with the surface of the subsequent layer containing the polymeric particles. Another patent details a recording material that includes a support and at least one layer of core/shell polymeric particles, which also have at least one void when dry, along with an opacity reducer. Additionally, a method for providing an image using the recording sheet is included.
