| titleOfInvention | Manufacturing method of fired colored pencil lead |
| abstract | [57] [Abstract] [PROBLEMS] To draw a line with excellent light resistance and weather resistance while having vivid coloration and sufficient line density, excellent mechanical strength such as bending strength, and easy to erase with an eraser. In particular, the present invention provides a method for producing a fired colored pencil lead suitable for a small-diameter colored pencil lead for a mechanical pencil. SOLUTION: A white or light-colored porous fired core is formed, and at least the following formula (I) is contained in pores of the fired core. After dissolving the compound represented by in an organic solvent and filling, A method for producing a fired colored pencil lead, wherein the compound is heated to form a pigment in the pores.
