PROBLEM TO BE SOLVED: To provide a color drawing material which has a lighter writing touch than known color drawing materials using fats and oils such as liquid paraffin, waxes such as carnauba wax, and terpene resins to give stickiness, has good color developing properties, and generates a very small amount of residues in layered coating. SOLUTION: The color drawing material at least comprises a coloring agent, a polybutene, and one or a mixture of two or more selected from an ethylene-propylene-butene copolymer, an amorphous polypropylene, an ethylene-polar monomer copolymer, a polyethylene, a polyisobutylene, and an amorphous poly-α-olefin.
