- Patent Document 2 JP-A-01-283583
- the present invention provides a method for transferring holograms and the like with stable quality including on-demand information using a thermal transfer sheet on which holograms and the like are laminated.
- the inventor of the present invention has found that the area unit of the thermal energy applied from the heating element as the heat source is small! / ⁇ When transferring a hologram or the like by a thermal head or the like, the energy is applied sequentially, We found that irregularities of about 0.5 m-several / zm were formed in each of the forming units, and that the interference effect caused by interference fringes and diffraction gratings formed on the assumption of a flat surface without irregularities was broken. In addition, it has been found that the irregularities generated for each of the forming units are almost horizontal in the direction in which they are continuously formed, and almost do not hinder the interference effect.
- the hologram and the like are thermally transferred so that the direction of continuous heating by the heat source and the direction of recorded information for enhancing the optical effect of the hologram and the like are the same.
- the recorded information is recorded substantially horizontally, and the optical effect of the recorded information is not lost.
- the heat source may be a heating element of a thermal head or a laser.
- the hologram may be a rainbow hologram, or an interference fringe may be formed in an interference fringe forming area constituting the entire hologram in units of an element area obtained by dividing the area horizontally. It may be a hologram.
- the "forming unit” corresponds to an area unit of heat energy applied from a heat source.
- the heat source is a heating element, it refers to a range that can be heated by one heating element.
- the irradiation range that can be irradiated at one time.
- the “direction of recording information for enhancing the optical effect” means, for example, that interference fringes formed based on object light having correlation only in the horizontal direction are ignored, ignoring object light diffused in the vertical direction. Accordingly, a hologram that forms a hologram image that takes into account only parallax in the horizontal direction refers to the horizontal direction.
- the “direction of the recorded information” is the horizontal direction.
- the "small area unit” is only required to be sufficiently smaller than the area of the hologram or the like to which the above-mentioned formation unit is to be transferred.
- the present invention may be embodied as a medium to which the hologram or the diffraction grating has been transferred by the transfer method described above.
- the direction in which heating is performed continuously by a heat source in units of minute areas and the direction of recording information for enhancing the optical effect of a hologram or a diffraction grating are in the same direction.
- FIG. 1 is a view showing an example of a thermal transfer sheet used in the present embodiment.
- FIG. 2 is an enlarged view of a part of interference fringes of a computer generated hologram provided on a transfer layer of the thermal transfer sheet of FIG.
- FIG. 3A is a view showing how the thermal transfer sheet of FIG. 1 is heated by a thermal head.
- FIG. 3B is a view showing heating by the heating element of FIG. 3A.
- FIG. 4 is a view showing how the thermal transfer sheet of FIG. 1 is heated by a laser.
- FIG. 5 is a view showing how a diffraction grating expressing a color image is transferred.
- FIG. 1 is a view showing an example of a thermal transfer sheet for realizing the present invention.
- the thermal transfer sheet 1 has a transfer layer 3 and an adhesive layer 4 laminated on a base film 2.
- interference fringes of a computer generated hologram are formed.
- information on light interference is recorded so that characters and images can be represented by the reproduction light when transferred to the transfer-receiving medium.
- the details of the interference fringes of the computer generated hologram in the transfer layer 3 will be described later.
- the transfer medium is applied to the adhesive layer 4 side, and when heat energy from a predetermined heat source is sequentially applied in the substrate film side force direction A, the adhesive layer 4 adheres to the transfer medium and the transfer layer 3 becomes the base material.
- the film is peeled from the film 2 and the computer generated hologram in the transfer layer 3 is transferred to the transfer medium.
- the direction A is referred to as a heating direction A.
- interference fringes of a computer generated hologram in the transfer layer 3 will be described with reference to FIG. 2 in which a part of the computer generated hologram is enlarged.
- the interference fringes of the computer generated hologram of the present embodiment are formed in units of band-shaped element regions 5 obtained by slicing the interference fringe formation region in the horizontal direction B with a predetermined slice width P.
- the slice width P is 10 ⁇ m-100 ⁇ m. Dry in each element area 5 Parallax information in the horizontal direction B is recorded in the interference fringes.
- the computer generated hologram in the present embodiment expresses a hologram using only the parallax information in the horizontal direction B. That is, the direction of the recorded information for enhancing the optical effect of the computer generated hologram in the present embodiment is the horizontal direction B.
- Such a computer generated hologram can be obtained by a known computer generated hologram manufacturing method.
- this horizontal direction B is referred to as the interference fringe direction B.
- the computer generated hologram is provided on the transfer layer 3 such that the heating direction A of the thermal transfer sheet 1 and the direction B of the interference fringes are the same.
- the thermal head 10 of the present embodiment is configured by arranging a plurality of heating elements 11...
- the thermal transfer sheet 1 is continuously heated in the heating direction A by applying the thermal head 10 to the base film 2 side of the thermal transfer sheet 1 and moving in the heating direction A.
- the direction B of the interference fringes of the computer generated hologram forming the transfer layer 3 that is, the direction of the recording information for enhancing the optical effect is the same as the heating direction A. Therefore, the transfer layer 3 is sequentially heated in the direction of the recording information.
- the thermal head 10 moves in the heating direction A, a plurality of transfer units 12 having a transfer width q corresponding to each heating element 11 are formed.
- the transfer unit 12 will be described with reference to FIG.
- the heating range 13 heated by the heating element 11 has a substantially circular shape.
- the heating range 13 also moves in the heating direction A.
- substantially band-shaped transfer units 12 having a drawing width q are formed corresponding to the respective heating elements 11.
- the drawing width q is a value proportional to the heating range 13 of the heating element 11, and is 50 m to several hundreds / z m in the present embodiment.
- irregularities that cause a problem hardly occur in the transfer unit 12, but irregularities that are a problem easily occur between adjacent transfer units 12, that is, in a side portion 12a parallel to the heating direction A.
- the unevenness generated between the transfer units 12 occurs in the same direction as the heating direction A, that is, the direction B of the interference fringes, the optical effect of the interference fringes of the computer generated hologram is not impaired.
- the present invention is not limited to the above-described embodiment, and may be implemented in various embodiments.
- heating Alternatively, a force laser using a thermal head may be used.
- the transfer medium is applied to the adhesive layer 4 side of the thermal transfer sheet 1 and the laser is applied from the base film 2 side to move in the direction C.
- this is referred to as irradiation direction C.
- This irradiation direction C is the heating direction. Therefore, as shown in FIG. 4, the irradiation may be performed so that the irradiation direction C and the direction B of the interference fringes coincide.
- the hologram formed on the transfer layer 3 may be a rainbow hologram.
- the transfer layer 3 is laminated on the thermal transfer sheet 1 so that the direction in which the parallax information is recorded as the interference fringe is the direction B of the interference fringe, and the thermal head or the thermal hologram is formed in the same manner as in the case of the computer generated hologram described above. What is necessary is just to heat in the heating direction A or C with a laser. Further, a release layer may be provided between the transfer layer 3 and the base film 2 to enhance the releasability due to heat, or another transfer layer on which other necessary or temporary information is printed may be provided. It may be further laminated on the base film 2. When a laser is used as the heat source, a light-to-heat conversion layer may be provided between the base film and the transfer layer.
- the transfer layer 3 may be provided not only with interference fringes forming a hologram but also with a diffraction grating.
- a color image 20 as shown in FIG. 5 is represented by a diffraction grating
- a color is represented by the area ratio of the diffraction gratings 22R, 22G, and 22B that represent RGB for each pixel 21.
- the “direction of the recording information that enhances the optical effect” is the direction D in which the diffraction grating in the direction perpendicular to the color image 20 is recorded. Therefore, for example, when the thermal transfer sheet 1 is heated by the thermal head 10, the thermal head 10 may be moved in the same direction as the direction D so that the heating direction matches the direction D.
