| titleOfInvention | Water-soluble calcined colored pencil lead and method for producing the same |
| abstract | (57) [abstract] (with correction) [PROBLEMS] To provide a water-soluble calcined pencil lead excellent in coloring, drawing line density, light resistance, and water-soluble drawing line and suitable for a high-strength mechanical pencil, and a method for producing the same. I do. SOLUTION: A pencil lead containing a pigment represented by the formula (I) and at least one of compounds represented by the formulas (II) to (IV) in pores of a fired core of a white or light colored happiness room. A (B) x ... (I) (x: an integer of 1 to 8, A: a chromophore residue such as quinacridone, anthraquinone, etc., represented by an atom for maintaining one of N, O, and S in A) B and B, B: H, or at least one of -C (O) -L other than H, and L is a group that expresses solubility) (R: alkyl having 10 to 20 carbon atoms, alkenyl, n: 2 An integer greater than or equal to 0) |
