In this paper the functional composite-pigment was prepared by dry impact-blending method, using inorganic materials used for paper coating such as TiO₂, CaCO₃, and clay. Dry impact-blending is used for making new functional material by surface modification and composition. After considering particle size of inorganic pigment, selected core powder and fine powder were mixed at a suitable mixing ratio. When powder was electrified, the fine particles of them could be adhered on the larger ones called'core particles' by static electricity, and then formed an ordered mixture. Afterward, these were susceptible to be composited by impact force resulting from very high-speed air circulation. Composite pigment formed was tested with powder physics tester and resulted in improvement of both fluidity and flushing. It also resulted in excellent optical property. Since design of particle pigment and application to a field of paper can be come true, it is thought that complementation in terms of both principle and application is possible, and that R&D for the production of various functional paper products can be activated.
