[0015]

FIG. 1 is a schematic view showing an example of a method for manufacturing a lenticular lens sheet print 24 of the present invention. As described in detail in FIG. 2, the thermal transfer sheet used here includes a color material transfer section 22 in which at least one or more sublimable dye layers 14 are provided on a base film 12 in a plane-sequential manner. White layer transfer unit 23 provided with at least a white layer 16 having a total light transmittance of 60% or less.
Are integrated thermal transfer sheets (hereinafter, referred to as thermal transfer sheets 4) provided face-to-face. When the lenticular lens sheet 1 has poor dyeing properties, the receiving layer transfer section 21 in which at least the receiving layer 18 is provided on the base film 12
The thermal transfer sheet 4 provided on the same surface of the base film 12 in the order of the receiving layer transfer section 21, the color material transfer section 22, and the white layer transfer section 23 can be used.

The formation of a pseudo image on the back surface 3 of the lenticular lens sheet 1 is performed by placing a thermal transfer sheet 4 and a lenticular lens sheet 1 between a flat platen 7 or a platen roller (not shown) and a heating device 6 such as a thermal head. The lenticular lens sheet 1 is heated by the heating device 6 while moving the lenticular lens sheet 1 in the direction A in this state, and each transfer layer is transferred and formed from the thermal transfer sheet 4 onto the lenticular lens sheet 1. .

The lenticular lens sheet 1 is moved by moving the flat platen 7 or rotating the platen roller.
Move in the direction. The thermal transfer sheet 4 is wound by the take-up roll 5 at the same speed as the moving speed of the lenticular lens sheet 1, and while the lenticular lens sheet 1 is moving in the A direction, one transfer layer is formed by the lenticular lens. The transfer is formed on the sheet 1.

The receiving layer 18 is transferred onto the lenticular lens sheet 1, the dye of each color is transferred to the receiving layer 18, and the white layer 16 and the like are sequentially transferred. When the lenticular lens sheet 1 moves in the direction A, first the receiving layer 18 is moved.
Is transferred. Next, the lenticular lens sheet 1
Is returned to the direction B, and stops at a predetermined position.
The first color dye layer 1 of the thermal transfer sheet 4 when moving in the direction
From 4 the dye migrates. Further, after the lenticular lens sheet 1 is returned in the B direction and stopped at a predetermined position, when the lenticular lens sheet 1 moves again in the A direction, the dye is transferred from the second dye layer 14 of the thermal transfer sheet 4. Thus, A → B
The moving direction is changed in the order of → A → B →, and each dye layer 14 of the thermal transfer sheet 4 is placed on the lenticular lens sheet 1.
The white layer 16 having a total light transmittance of 60% or less after transfer is transferred to form a lenticular lens sheet print 24 having excellent white hiding properties. When returning to the direction B, the close contact between the heating device 6 and the lenticular lens sheet 1 is released.

When the lenticular lens sheet 1 is returned in the direction B, the thermal transfer sheet 4 wound up at the same speed as the lenticular lens sheet 1 is not rewound with the lenticular lens sheet 1 and remains as it is. The cue of the layer to be transferred is performed. Thus, the thermal transfer sheet 4
Are sequentially transferred to obtain a lenticular lens sheet print 24.

As described above, according to the method of manufacturing the lenticular lens sheet print 24, the transfer layers formed on the same base film 12 are transferred to the back of the lenticular lens sheet 1 by a series of continuous transfer operations. 3 to form a pseudo image.

Conventionally, an integrated thermal transfer sheet has not been used, and the dye layer 14 and the white layer 16 could not be formed on the same lenticular lens sheet 1 face-to-face.
After the dye layer 14 was transferred to form a pseudo image once, it was necessary to form the white layer 16 in a separate step, so that the pseudo image and the white layer 16 could not be accurately and simply provided in a short time. However, in the present invention, the dye layer 14 and the white layer 16 are transferred onto the same lenticular lens sheet 1 in a series of continuous operations by using an integrated thermal transfer sheet, and one thermal head (heating device 6) is used.
Therefore, the pseudo image is less likely to be misaligned, and its formation is extremely simple. As a result, the pseudo image and the white layer 16 could be provided on the lenticular lens sheet 1 accurately, simply and in a short time. As a result, it becomes possible to form a pseudo image in a small printer, so that it is hardly contaminated by dust and the like, and there is little color blur due to misregistration,
A lenticular lens sheet print 24 on which a high quality pseudo image is formed can be obtained.

FIG. 2 shows a thermal transfer sheet 4 used in the method for producing a lenticular lens sheet print 24 of the present invention.
It is a schematic diagram which shows an example of a structure. The thermal transfer sheet 4 used in the present invention has a receiving layer transfer section 21 in which a release layer 17, a receiving layer 18, and an adhesive layer 19 are laminated in this order on one surface of the base film 12, A color material transfer section 22 in which yellow, magenta and cyan dye layers 14 are provided in a plane-sequential manner, and a white layer transfer section 23 in which a release layer 15 and a white layer 16 are laminated in this order are provided in a face-to-face manner. ing.

The base film 12 is provided on the other side,
One provided with the heat-resistant layer 13 can be used.

The white layer 16 has a total light transmittance of 6 after the transfer.
The heating device 6 (thermal head or the like) having the same size as the pseudo image or a size slightly larger than the pseudo image on the formed pseudo image adjusted by the white pigment and the binder resin so as to be 0% or less. Is transferred and formed.

The white layer 16 may contain an adhesive resin binder, if necessary, and may be transferred onto a pseudo image without using an adhesive layer. In the case where the lenticular lens sheet 1 has poor dyeing properties, the receiving layer transfer section 21 is placed on the base material film 12 by the color material transfer section 22.
It is preferable to provide the receiving layer transfer portion 21 when the lenticular lens sheet 1 has good dyeing properties.

As described above, in the thermal transfer sheet 4 used in the present invention, all necessary layers such as the receiving layer 18, the dye layer 14, the white layer 16 and the like are provided on the same surface of the base film 12. Therefore, a pseudo image can be simply and efficiently formed on the lenticular lens sheet 1 from one thermal transfer sheet 4 by a series of continuous transfer operations.

FIG. 3 is a sectional view showing an example of the lenticular lens sheet print 24 of the present invention. The lenticular lens sheet print 24 is formed by the method described above.
The image is transferred from the thermal transfer sheet 4 onto the back surface 3 of the lenticular lens sheet 1, and an adhesive layer 19, a receiving layer 18 (including a pseudo image), a white layer 16 and a release layer 15 are laminated and formed in this order.

The receiving layer 18 having excellent dyeing properties is separated from the boundary surface with the release layer 17 provided with good adhesion on the base film 12, and is provided on the back surface 3 of the lenticular lens sheet 1 via the adhesive layer 19. Is transferred and formed. For this reason, it is possible to form a pseudo image even on the lenticular lens sheet 1 having poor dyeing properties. In the case where the lenticular lens sheet 1 has excellent dyeing properties, the pseudo image can be obtained without providing the receiving layer 18.
Can be formed directly on top.

When the dye layer 14 is not provided on the base film 12 with good adhesion, the adhesion between the base film 12 and the dye layer 14 is improved by subjecting the base film 12 to an easy adhesion treatment. Can be done.

On the other hand, the adhesion between the base film 12 and the receiving layer 18 may be unnecessarily strong by the easy adhesion treatment. However, the receiving layer 18 must be easily separated from the base film 12 and transferred to the lenticular lens sheet 1. Therefore, the receiving layer 18 can be easily transferred onto the lenticular lens sheet 1 by providing the release layer 17 between the base film 12 that has been subjected to the easy adhesion treatment and the receiving layer 18. Further, in order to improve the releasability of the receiving layer 18 itself, a predetermined ratio of a release agent as described later may be contained in the receiving layer 18.

After the transfer of the receiving layer 18, the heat transfer sheet 4
Yellow, magenta,
A pseudo image is formed by sequentially transferring the dyes in the cyan dye layer 14 to the receiving layer 18 by thermal transfer. At this time, a black dye layer can be provided if necessary. Each dye layer 14 may be a sublimable dye or a hot-melt ink, and is provided with good adhesion on the base film 12 that has been subjected to the easy adhesion treatment.
The dye can be transferred to the receiving layer 18 satisfactorily, and a synthesized pseudo image with good gradation can be formed.

On the receiving layer 18 on which the pseudo image is formed,
The white layer 16 provided on the same surface of the thermal transfer sheet 4
It is transferred and formed together with the release layer 15 by thermal transfer. In the white layer 16, the ratio between the white pigment and the binder resin is adjusted to an appropriate range so that the total light transmittance after transfer is 60% or less.

In order to further improve the white opacity, the release layer 15 transferred simultaneously with the white layer 16 may contain a white pigment. Thereby, even if the ratio of the white pigment in the white layer 16 is reduced and the total light transmittance exceeds 60% and the white hiding property is insufficient, the shortage can be compensated.

As described above, according to the present invention, when the lenticular lens sheet 1 has a dyeing property, the color material transfer part 22 and the white layer transfer part 23 or the lenticular lens sheet 1 has a dyeing property. In the case of being poor, the receiving layer transfer unit 21, the color material transfer unit 22, and the white layer transfer unit 23
Since they are provided on the same base film 12 in a plane-sequential manner, it is possible to efficiently form a pseudo image and manufacture the lenticular lens sheet print 24 by a series of continuous transfer operations. For this reason, it is possible to prevent dust from being mixed, and it is suitable for minimizing the positional deviation at the time of forming the pseudo image, so that the pseudo image can be transferred and formed with high accuracy, and the lenticular lens sheet printing The manufacture of the product 24 is also facilitated. In addition, the size and cost of a printer for transferring images can be reduced. Further, by adjusting the ratio of the white pigment and the binder resin in the white layer 16 or by including the white pigment in the release layer 15, the white hiding property can be maintained or improved, and the white hiding property is excellent. The lenticular lens sheet print 24 can be manufactured easily and in a short time. Further, by adjusting the white pigment, it becomes possible to obtain a backlight type lenticular lens sheet print 24 having good transparency.

In order to enhance the releasability from the substrate film 12 during transfer, polysiloxane grafted to the main chain of an acrylic, vinyl, polyester, polyurethane, polyamide or cellulose resin is used. A graft copolymer having at least one releasable segment selected from a segment, a fluorocarbon segment and a long-chain alkyl segment may be used as the binder resin.

The organic filler contained in the dye layer 14 may be any organic filler having good wettability with the coating solution for the dye layer.
The following polymer materials or fillers of a composition composed mainly of them can be used. For example, phenol resin, melamine resin, urethane resin, epoxy resin, silicone resin, urea resin, diallyl phthalate resin,

Apply the coating liquid to the base film 12
It can be formed on the top by applying by means of a gravure printing method, a screen printing method or a reverse coating method using a gravure plate and drying.

Next, the white layer transfer section 23 will be described. The white layer transfer section 23 includes a white layer 16 for imparting an appropriate concealing property and the like to the lenticular lens sheet print 24 after transfer, and a release layer for smoothly releasing the white layer 16 from the base film 12. 15 is provided.

(White Layer) The white layer 16 used in the thermal transfer sheet 1 is composed of a white pigment for imparting an appropriate white hiding property and light diffusing property to the printed matter 24 after transfer, and a binder resin. I have. In the case where the white layer 16 is transferred onto the pseudo image without using the adhesive layer, a conventionally known binder resin having adhesiveness may be used, or an adhesive may be contained. As the white pigment, a filler can be used in addition to a typical white pigment. Therefore, the filler is included in the white pigment here.

The white pigment is hard solid particles, for example, a white pigment such as titanium oxide or zinc oxide, silica,
Uses inorganic fillers such as alumina, clay, talc, calcium carbonate or barium sulfate, and resin particles (plastic pigments) such as acrylic resin, epoxy resin, polyurethane resin, phenol resin, melamine resin, benzoguanamine resin, fluororesin or silicone resin. Can be Note that the titanium oxide includes rutile-type titanium oxide and anatase-type titanium oxide, and any of them may be used.

The white layer 16 may contain a fluorescent whitening agent in addition to the white pigment and the binder resin.
As the fluorescent whitening agent, a known compound having a fluorescent whitening effect, such as a stilbenzene compound or a pyrazoline compound, can be used. Further, the white layer 16 may contain some coloring agent.

When the lenticular lens sheet print 24 to which the white layer 16 has been transferred is viewed with transmitted light from a backlight, the white layer 16 needs to have appropriate light diffusion and light transmittance. When the lenticular lens sheet print 24 to which the lenticular lens sheet is transferred is viewed with reflected light from the front, it is necessary to have appropriate light diffusion and light reflection. In the latter case, the total light transmittance of the white layer 16 after transfer is preferably 60% or less, and particularly 50% in the case of forming a pseudo image as a continuous image.
The following is preferred.

The total light transmittance of the white layer 16 after transfer is 60
% Or less, and in order to impart sufficient white hiding power, the ratio between the binder resin (A) and the white pigment (B) constituting the white layer 16 is adjusted so that A / B = 1/1 to 1/10. It is preferable to set the range. It is particularly preferable to set the lower limit of the ratio to 1 / 1.5 or the upper limit to 1/6. The ratio of A / B is appropriately set within the range according to the material of the lenticular lens sheet 1 or the receiving layer 18 to which the white layer 16 is to be transferred. A / B is 1/1
If it is larger than this, the total light transmittance may exceed 60% and the white opacity may decrease. Further, if the ratio of A / B is smaller than 1/10 by increasing the amount of white pigment, the coating properties are deteriorated, so that the abrasion may be inferior or the adhesiveness may be lowered due to the decrease in the resin content.

The thickness of the white layer 16 is about 0.5 to 10 μm.

The measurement of the total light transmittance is performed according to JIS K71.
05. White layer transfer section 23 of thermal transfer sheet 4

(Release Layer) The release layer 15 used in the thermal transfer sheet 4 constitutes a white layer transfer portion 23 together with the white layer 16 and is formed between the base film 12 and the white layer 16. The release layer 15 prevents fusion between the thermal transfer sheet 4 and the lenticular lens sheet 1 and allows the white layer 16 to be easily transferred onto the receiving layer 18 provided on the lenticular lens sheet 1 without transfer unevenness. Provided.

As the release layer 15, for example, the release layer 15
And a release layer separated at the interface of the base film 12 and
Cohesive failure occurs in the release layer 15 and the base film 1
A cohesive release layer that separates from the cohesive release layer can be formed.

The release layer can be formed by adding a release material to the binder resin as required. Usable binder resins include thermoplastic resins such as polymethyl methacrylate, polyethyl methacrylate, acrylic resins such as polybutyl acrylate, polyvinyl acetate, vinyl chloride-vinyl acetate copolymer, polyvinyl alcohol, and polyvinyl alcohol. Vinyl resins such as butyral, cellulose derivatives such as ethyl cellulose, nitrocellulose, and cellulose acetate, or thermosetting resins such as unsaturated polyester resins, polyester resins, polyeletan resins, amino alkyd resins, and the like. Alternatively, the releasable release layer can be composed of a composition comprising two or more kinds.

As the releasing material, waxes,
Resin having releasability such as silicone wax, silicone oil, silicone resin, melamine resin and fluorine resin, fine particles of talc and silica, and lubricant such as surfactant and metal soap can be used.

The releasable release layer may be made of a resin having releasability. In this case, silicone resin,
Melamine resin, fluorine-based resin, etc. can be used, using a graft polymer in which a releasable segment such as a polysiloxane segment or a fluorocarbon segment is grafted into resin molecules such as an acrylic resin, a vinyl-based resin, or a polyester resin. Or a composition composed of one or more of the above resins. In addition to the above-mentioned materials, a conventionally known fluorescent whitening agent having a fluorescent image whitening effect such as stilbenzene or pyrazoline may be added to the release layer.

When the white layer transfer portion 23 is transferred onto the receiving layer 18, the cohesive failure release layer causes a so-called cohesive failure near the middle of the release layer 15 in the thickness direction. The remaining part is not removed from the material film 12, and the other part is transferred onto the print 24. When the cohesive failure release layer is peeled off and transferred onto the lenticular lens sheet 1, the print 2
On the outermost surface of No. 4, an uneven shape of the cohesive failure surface is formed. The unevenness formed on the outermost surface of the print 24 diffuses and reflects the irradiated light, for example, in the case of viewing with transmitted light from a backlight. This replenishes the light diffusing property of the white layer 16 and can form a print 24 having good light diffusing property and light transmitting property and having good appearance.

As a material for forming the cohesive failure release layer, a binder resin and a release material added as necessary are used. As the binder resin, a thermoplastic resin such as polymethyl methacrylate, an acrylic resin such as polyethyl methacrylate or polybutyl acrylate, polyvinyl acetate, a vinyl chloride-vinyl acetate copolymer, polyvinyl alcohol or polyvinyl butyral, etc. One or more resins such as a vinyl resin, a cellulose derivative such as ethyl cellulose, nitrocellulose or cellulose acetate, a polyester resin or a polyurethane resin can be used.
