Abstract
PURPOSE:To accurately protrude the leading end of each color ink layer, by covering a base with a back coat layer having a coefficient of friction lower than that of the base, on the back side opposite to the side of the ink layers and markers. CONSTITUTION:A color ink ribbon 1 comprises ink layers 3A, 3B, 3C provided on a base 2, and markers 4 different in length provided on the base 2. A colorless transparent back coat layer 5 is provided on a surface of the base 2, the layer 5 being formed of a material having a coefficient of friction by far lower than that of the base 2. When color printing is conducted, the color ink ribbon 1 is fed at a constantly fixed velocity together with a paper 20 notwithstanding the contact of the base 2 with the paper 20, because the coefficient of friction of the surface of the back coat layer 5 making contact with a thermal head 16 is by far lower than that of the base 2. Since the back coat layer 5 is colorless and transparent, it does not hinder the passage of light which is to travel from a light emitter 23 to a light receiver 24, and a sensor 10 accurately discriminates the colors of the ink layers 3 by the markers 4. Accordingly, an operation of protruding the leading end of each of the ink layers 3 can be carried out accurately, and color printing with favorable quality can be performed.
