摘要： Non-baked color pencil leads are obtained by forming a blend composition from a filler, a coloring agent, a binder without any wax, and a water/oil repellant substance, kneading the mixture with a solvent and/or plasticizer, extruding the kneaded material, drying the extruded articles to remove the solvent and/or plasticizer therefrom to form open pores therein owing to the less wettability of the water/oil repellant substance, and then impregnating the pores with an oil, a fat and/or a wax. Since the oil, the fat and/or the wax is not blended into the composition, bleeding does not occur at the time of the drying, which permits drying the articles at a high temperature for a short period of time, whereby the manufacturing cost can be decreased. The thus obtained non-baked color pencil leads are remarkably excellent in physical properties such as bending strength and pointed end strength and have a smooth writing performance.
