BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer film for thermal transfer printing used in thermal transfer printing, and more particularly to at least one reflection coating layer and transmission coating layer on one surface of a substrate film via a release layer. The present invention relates to a transfer film for thermal transfer printing, in which a transfer coating film layer having a plurality of layers laminated on each other is formed and an adhesive layer for adhering the transfer coating film layer to a mating member is formed on the transfer coating film layer.

[0003]

2. Description of the Related Art Conventionally, as a transfer film for this type of thermal transfer printing, for example, as disclosed in Japanese Patent Publication No. 59-19834, a release layer, a reflective coating layer and a metal vapor deposition layer are formed on one surface of a base film. Only a proposal has been made of one prepared by sequentially laminating a transfer coating layer composed of the above and the adhesive layer one by one.

[0004]

[Problems to be Solved] However, in a conventional transfer film for thermal transfer printing, it is only necessary to dispose a transfer coating film layer composed of a reflective coating film layer and a metal vapor deposition film layer, etc. on a substrate film via a release layer. Therefore, when the transfer coating film layer was transferred to the mating member, if the mating member was formed of an opaque material, there was no problem in visually recognizing the transfer coating film layer by reflected light. (i) If the mating member is formed of a transparent or light-transmissive material, the transfer coating layer is thin and inferior in light shielding property as compared with the case where the transfer coating layer is formed by coating or the like. There is a drawback that the reflectance of light is too low to be visible by reflected light, and a turbid color (that is, dark color tone) is exhibited, and (ii) Attempt to visually check the transfer coating layer by transmitted light at night. Sometimes the color of the transferred coating layer is reflected light because it is easily affected by the color tone of transmitted light. There is a drawback that it is visually recognized differently from the color when viewed, and (iii) it cannot be practically adopted when transferring to a partner member formed of a transparent or light-transmittable material, and the range of use cannot be expanded. There was a flaw.

Therefore, in order to eliminate these drawbacks, the present invention provides a transfer having at least one reflection coating layer and transmission coating layer laminated on one surface of a substrate film with a release layer interposed therebetween. It is intended to provide a transfer film for thermal transfer printing in which a coating film layer is formed and an adhesive layer for adhering the transfer coating film layer to a counterpart member is formed on the transfer coating film layer.

And a transfer coating layer 13 for providing an appropriate color by reflected light and transmitted light when heat-transfer printed on the counterpart member W, and thermal transfer to the counterpart member W disposed on the surface of the transfer coating layer 13. An adhesive layer 14 formed of an appropriate known material is provided for suitably bonding the transfer coating layer 13 to the mating member W during printing. Transfer coating layer
13 is an appropriate coating pattern (here, four strips) corresponding to the coloring pattern of the mating member W (that is, the pattern of the coloring region). Along with this, the release layer 12 and the adhesive layer 14 may also have an appropriate coating pattern (here, four strips) corresponding to the coloring pattern of the mating member W (that is, the pattern of the colored region).

The transfer coating layer 13 has a reflective coating layer 13A formed by applying or printing a paint or ink having a desired color on the surface of the release layer 12 and a surface of the reflective coating layer 13A.

When printing the reflection coating layer 13A and the transmission coating layer 13B of the transfer coating layer 13, well-known printing techniques such as gravure printing, offset printing, silk screen printing may be adopted as desired. The thickness of the transfer coating layer 13 may be appropriately determined as desired or necessary, but may be 10 μm or less, for example. The pigment contained in the paint or the ink for forming the reflective coating layer 13A and the transparent coating layer 13B of the transfer coating layer 13 is clearly visible when viewed by both reflected light and transmitted light. It is rarely used alone as it is preferred. Transfer coating layer
