Description

Description: TECHNICAL FIELD The present invention relates to a thermal transfer ribbon and a method for decorating a character pattern formed using the same using a metal transfer foil or a pigment transfer foil.

[Prior art] Conventionally, a desired design such as a character pattern is copied by a toner-based copying machine, and a metal transfer foil or a pigment transfer foil is superimposed on the toner and pressed under heating to apply a character according to toner printing. It is known to decorate a desired design such as a pattern in a metallic tone or a pigment color.

On the other hand, a character pattern printed on a conventional thermal transfer ribbon used for a thermal transfer printer in a word processor, a computer, or the like cannot be decorated using a conventional metal transfer foil or pigment transfer foil.

Therefore, the character pattern printed on the conventional thermal transfer ribbon is copied once with a toner-based copying machine, and a metal transfer foil or pigment transfer foil is superimposed on the toner and pressurized under heating to apply the character pattern according to the nonner printing. There is a disadvantage that it is necessary to decorate a desired design with a metallic tone or a pigment color.

[Problems to be Solved by the Invention] In view of the drawbacks of the prior art, the present invention uses a thermal transfer ribbon to print a design such as a desired character pattern using a thermal transfer printer, and then superposes and heats a metal transfer foil or a pigment transfer foil. It is an object of the present invention to make it possible to decorate a desired design such as a character pattern as printed with a metallic tone or a pigment color by applying pressure under or without heating.

[Means for Solving the Problems] That is, the present invention relates to a thermal transfer ribbon for a thermal transfer printer for forming a character pattern for decorating using a transfer foil after thermal transfer printing, wherein a thermal transfer ribbon is provided on a base film. Provided is a thermal transfer ribbon characterized by forming a heat-sensitive and pressure-sensitive adhesive ink layer having a heat transfer property and exhibiting adhesiveness under heating and pressure or a resin exhibiting adhesiveness under pressure at room temperature as a main component. I do.

The present invention further provides a heat-sensitive and pressure-sensitive adhesive ink layer having, as a main component, a resin having thermal transferability and exhibiting adhesiveness under heating and pressure or exhibiting adhesiveness at normal temperature under pressure, on a base film. After printing a desired character pattern with a thermal transfer printer using the formed thermal transfer ribbon, the transfer layer side of the desired metal transfer foil or pigment transfer foil is overlaid and pressurized under heating or non-heating, and the above-described printer is used. Provided is a method for creating a character pattern in which a printed character pattern is decorated with a desired metal transfer foil or pigment transfer foil.

[Functions and Examples] Since the thermal transfer ribbon of the present invention has a heat-sensitive and pressure-sensitive adhesive ink layer, characters and the like printed by using this are copied by a conventional toner-using type copying machine. A metal transfer foil or a pigment transfer foil can be superimposed on the print, and the desired design, such as a character pattern as printed, can be decorated with a metal tone or pigment color by pressing under heating or without heating. And the disadvantages of the prior art are eliminated.
