Abstract

PURPOSE: To obtain a colored leader tape which has a sufficient cleaning effect and is easy to discriminate, by causing particles of a specific stiffness and a specific particle diameter to adhere to the part near the colored support material face without a binder.
CONSTITUTION: 1W10 particles (for example, iron oxide, tungsten carbide, etc.,) 14 of Mohs hardness of 5 or moroe (desirably, 5.5 or more) and an average particle diameter of 8μ or less (desirably, 0.4W4μ) are caused to adhere per support material surface 100μ2 into concave 13 of support material 11 which is colored and is caused to include filling particles 15 and is made rough by providing convexes 12 and concaves 13. In respect to the method to cuse particles 14 to adhere to concaves 13, for example, suspension of particles of an average particle diameter of approximately 0.5W30μ is sprayed to the support material surface strongly, and next, the support material is washed with water to remove excessive particles. (Particles of a large diameter are exfoliated and removed, and as the result, particles of a diameter of approximately 6W8μ of less are held in concaves and are left).
