[Problem] To provide a coating agent having a high affinity with a coating substrate, no problem of increasing the number of coating steps, an antistatic function, and a high friction coefficient. A polyurethane water dispersion and conductive carbon black are blended, and the blending ratio is 83:17 to 67:33 in terms of volume fraction of urethane resin and conductive carbon black constituting the polyurethane water dispersion. It is a range. [Selection figure] None |
