Abstract

PURPOSE:To cause a coating material layer to be exposed on a copy layer at the time of transfer recording and thereby enable color transfer recording, by using a base sheet obtained by providing a silicone layer as a releasing agent on a main body of a sheet and providing a synthetic resin base coating material layer thereon. CONSTITUTION:The silicone layer 2 comprised of a silicone base resin releasing agent is provided on the main body 1 of the sheet formed of a synthetic resin, a paper or the like, and then a synthetic resin base coating material is uniformly applied onto the silicone layer 2 to form the coating material layer 6. The copy layer 3 is provided on the thus obtained base sheet by a copying machine, and then the entire surface is lightly wiped by a cloth impregnated with a solvent or the like so that the coating material layer 6 at parts where the copy layer 3 is not formed is removed by dissolving in the solvent. Thereafter, an adhesive layer 4 is formed to obtain a color transfer sheet. When this is transferred onto a paper 11, toners contained in the copy layer 3 covered with the coating material layer 6 is released from the silicone layer 2 and is adhered to the paper 11, resulting in color transfer recording.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to the structure of a transfer sheet, particularly a pace sheet for color transfer sorting.

Transfer sorting is generally constructed by printing transfer characters and other information on a sheet body made of synthetic resin film, and as shown in FIG. Overlap, transfer sheet 1
The part of the letter 13 on the top of the letter 2 is transferred to the paper 11 below with a little more force, and it is recently called transfer lettering and is increasingly being used in the design and architectural design departments.

By the way, the transferred characters are printed as described above, and are actually printed by silk screen printing. As is well known, this printing method is a type of stencil printing method similar to a mimeograph, in which a frame is placed on a film or other printing medium, paint is applied to one end of a silk cloth mold, and this is applied with a squeegee. It is applied while stretching,
This printing method requires equipment costs and other costs.
Therefore, the transfer sheet itself has the disadvantage of being a direct value. Furthermore, since conventional transfer sheets are pre-printed with transfer characters, etc., the user has no choice but to select the desired one from among the given printed characters, which limits the use and versatility of the transfer sheet. It also has the disadvantage of being narrow. In fact, in the production of transfer sheets by multi-printing and silk screen printing, the production of only one sheet is practically never done, as Conut prints the E version.

Moreover, the printing of Teller transfer sheets (transfer sheets) was pre-printed with colors such as non-color or yellow, making it nearly impossible to manufacture just one sheet of paper.

The present invention has been made in view of the above-mentioned circumstances, and basically aims to provide a pace sheet for a transfer sheet, which is used in the previously proposed transfer notebook and method for manufacturing the same. That is, the present invention takes the previously proposed transfer sheet φ, which is usually limited to transfer in black color, to a further level, and makes it possible to ultimately eliminate transfer in a desired color. This is what I did.

In order to explain the base sheet of the present invention, the transfer sheet (hereinafter simply referred to as a transfer note) proposed earlier will be explained for convenience, and the present invention will be clearly explained in comparison with this. Make it.

The above-mentioned transfer sheet differs from the normal transfer sheet 1 which was made by Nruknu Clean Instant Printing, and its basic structure is to use electrophotographic copying which has become popular in recent years and can be easily used. This simplifies the production of the transfer sheet, thus lowering the cost, and improves the transfer quality and uses of the sheet itself compared to conventional products. A sheet body 1 such as a resin film or string is sequentially coated with a silicone layer 2 made of a silicone resin mold release agent and a copy layer 3 made of electrophotography.
and an adhesive layer 4 made of a pressure-sensitive adhesive.

The sheet main body 1 is made of synthetic resin film, paper, etc. as described above, but since electrophotography is used in the manufacturing process of the transfer sheet, it includes all sheet-like materials that can be copied. Preferably, the sheet body 1 is subjected to matte processing or other embossing.
'). This is because after the formation of the copy layer 3 and the adhesive layer 4, which will be described in detail later, the spread image powder of the copy layer 3 is not present, and the adhesive particles are in the recesses of the 2nd, jy, and surface of the notebook body 1. The force that enters the copy layer 3 during transfer (is the force that can be transferred well, and the other areas are the paper 1)
1 (See Figure 1) It is a good idea to avoid the problem of sticking with adhesive.

The cone layer 2 is obtained by so-called silicon processing of the sort body 1 (step (a) in Fig. 3).
The transfer of the copy layer 3 to a transfer target such as paper 1 in the figure, and the force required to peel the copy layer 3 against the thick sheet 1! This makes separation extremely easy. According to the inventor's experimental studies, it has been found that when a solvent containing toluene as a main component is used in silicon processing, the copying layer 3 can be transferred well.

The photosensitive material 3 is formed on the silicone layer 2 (0-layer process in FIG. 3), and is an electrophotographic photosensitive material 1.
F: Using a metal oxide, zinc oxide, etc., V) charging with corona group I, etc., and giving it photosensitivity, exposing it to electrostatic latent, and applying ++ powder. The powder image is then transferred to the image forming apparatus, and then the powder image is transferred and processed to produce a photograph (formed using a so-called copying machine).

According to the inventor's experiments, good transfer results have been obtained when the Hirakata layer 3 forms a dust image powder in a dry dust image method (dry method). In this way, since the copying layer 3 can be formed by electrophotography, it is not limited to existing transfer characters such as those on conventional transfer sheets, and can be used to print all types of characters, drawings, etc. that can be copied.
Of course, all the dungeons that you draw yourself can be made into the copy layer 3, and therefore, these can be transferred, greatly expanding the range of material speeds you can use. In addition, in the conventional transfer sheet manufacturing method using silk screen printing, it is virtually impossible to manufacture only one transfer sheet; in other words, it is extremely expensive to manufacture only one sheet. By forming the copying layer 3 by electrophotography as described above, the poisonous condition that inevitably occurs can be easily eliminated.

By the way, in the above-mentioned method for manufacturing a transfer sheet, when forming the copy layer 3, the transfer object 5 (such as characters or drawings) is
(Fig. 3) is added ((b) in Fig. 3).
process). For example, if a character is copied using electrophotography, the character will appear as a copy, but when it is transferred again, the character will appear reversed and upside down. If the characters can be displayed on a transparent film, tracing vapor, etc., the film may be reversed when copying. However, in many cases, the surface of the transfer target is not visible on the transparent film, so it is necessary to reverse the transfer as described above.
be. Therefore, while transferring the characters, drawings, etc., the decoration 5 is reversed with the plate making camera art (- or) Hiki Tsukuda girder,
This is enlarged or reduced to a desired magnification to produce a positive film, that is, a copy manuscript, and this copy manuscript is copied onto the silicone layer 2 of the sheet main body 1 using a kidney scanner.
form. Now, scale to the desired magnification as described above.
It is a tragedy that the content of pleasure should include 2 times the same size.

It should be noted that, in the production of the above-mentioned positive film, it is generally necessary to use a diffusion transfer type photosensitive side.

The adhesive layer 4 made of the pressure-sensitive adhesive is formed on the copying layer 3 (step in FIG. 3) and serves to fix the layer 3 to the object of transfer. In order to facilitate and ensure this fixation while also avoiding the sheet body 1 from sticking to the object, a pressure-sensitive adhesive with appropriate adhesive strength is selected, and the adhesive layer 4 is thin. It should be formed evenly and preferably transparent. The advantages of applying embossing to the sheet body 1 for women's bathing have been described above. According to the inventor's transfer experiments, good results were obtained when the adhesive layer 4 was formed by coating a resin adhesive having an alkyl group. In addition, it is clear that it is impossible to completely combine this adhesive layer 4 with the transfer force 1 and the initial transfer 3 due to the transfer force.

However, if the silicone layer 2 were not present, the transfer would be unsatisfactory and incomplete. In addition, the application of the powder is performed using a squeegee, Nuprey, etc.

The above-mentioned transfer sheet configured in this manner can be manufactured much more easily than conventional silk screen printing, and the manufacturing cost can be reduced. ζ, etc., you can select anything that can be copied on this transfer sheet 1 (wrinkle 1ζ, transferred characters, etc.).
2 also makes it extremely easy to produce only one transfer sheet, which was practically impossible in the past, and its uses and versatility are greatly expanded. In other words, (-'', conventional electronic copying has no ζ-h valleys, which is only on the top of the bee paper!): Although the force exists, and according to this transfer sheet,
Circle =: C71, s - object crab (as a result of expanding to a copyable object, it can be applied to any object such as glass, plastic, wood, etc. that has a transferable surface, and a surface with a surface that has a surface that has a surface that can be copied, and any place) , it became possible to copy indirectly.

A non-inventive feature of the above-mentioned transfer sheet is that it is possible to apply color to the transfer sheet. The base sheet according to the present invention has a basic base sheet of the transfer sheet, that is, a sheet body 1 with a silicone layer 2 formed thereon (FIG. 4), and an additional layer 1 (synthetic fiber paint K round paint layer). 6 (Fig. 5) 8 To explain this in detail, the paint layer 6 is made of a synthetic resin containing a pigment of an arbitrary color on the silicone layer 2. paint,
For example, it can be applied uniformly with a squeegee or the like. The base sheet of the present invention is normally manufactured by the supplier, and general consumers purchase it and, in principle, carry out the manufacturing operations of the series of transfer sheets described above.

When producing a transfer sealer using the Henneseer of the present invention, one step of applying force is applied during the above manufacturing process. A copying layer 3 is formed on the base sheet of the present invention shown in FIG.
The process shown in FIG. 6) is the process of removing the paint layer 6 other than the areas where the copy layer 3 is formed using a solvent, as described above.

This dissolution (ren, - for example, a cloth impregnated with a solvent,
Lightly rub the entire image surface of the base sheet of the present invention with soft paper or the like. At this time, the part where the copy layer 3 is formed, that is, the paint layer 6 where the toner has been completely formed, is masked and retained by the toner, so the solvent 1 (therefore, it is dissolved and removed as described above) is masked and retained by the toner. This is done in the portion where the copy layer 3 does not exist, that is, in the exposed paint tube 6. This state of g is shown in FIG.

After applying the adhesive 4 on the copying layer 3, the Fuffler transfer sheet is completed (FIG. 8). When this is transferred, as shown in FIG. It can be pasted on.

The upper surface of the toner transferred in this way is the paint tube 6, and the color transfer is subsequently smoothed. If the above-mentioned series of steps are compared and shown in FIG. 3, the process chart shown in FIG. 10 will be obtained. That is, when the base sheet of the present invention is used, step 0) is followed by step (a') for forming the paint layer 6, and step ← is followed by step (glue) for dissolving the paint layer 6. The process is incorporated separately.

Next, some supplementary explanation will be given regarding the paint layer 6 in the base sheet of the present invention in relation to the copy layer 3. As already clarified, when the base sheet of the present invention is used for transfer, the paint layer 6 is deposited on the copying layer 3, and as a result, the color 1 of the paint layer 6 itself appears on the surface. There is, but generally the copy layer
Since the toner 36 is black, it is important to pay attention to the color composition between the color of the paint 36 and the black color existing below. If the color is completely opaque and the material layer 6 is not affected by the black color of the material layer 3, there is a problem.・5-1
However, care must be taken as the color may be affected by the opacity of the paint layer 6 and its color (2).
It is preferable to apply a paint having the desired color and then apply a white paint to remove the black color of the toner. As described above, depending on the color of the paint layer 6, a good transfer color could be obtained by so-called two-coating.

In addition, the formation of the paint layer 6 itself, the adhesion of toner when the copy layer 3 is formed on the paint layer 6, and
Due to these series of steps, such as the subsequent dissolution and removal of the paint tube 6, the synthetic rosin-based paint for forming the paint layer 6 has a diameter of φ, which is mainly composed of acrylic resin, and a solvent to dissolve it. When using an alcohol-based product, each transfer experiment showed good quality. The dissolution temperature of these paints is the same as that described above, and the solvent used is one that does not dissolve the toner in the copying layer 3.

As explained above, the base sheet superior to the present invention is one in which a silicone layer is formed on the main body of the sheet, and a paint layer made of a synthetic tree fertilizer-based paint is formed on top of the silicone layer. When a transfer sheet is manufactured, a paint layer appears on the upper surface of the copy layer during transfer, resulting in so-called color transfer. According to the color transfer using the base sheet of the present invention, as an advantage of the production process in general design, it is possible to see a particularly remarkable labor saving in examining the finished state of color printing typified by package design. When designing a package, it is difficult to consider the color scheme of the finished product at the manuscript stage, so usually several so-called dummies are printed in a state similar to the finished product. The production of this dummy requires a lot of time and effort, but is it an uninvented base sheet? By using this method, it becomes possible to know the C state after printing in the case of color printing before the dummy is produced, making it extremely simple, easy, and inexpensive to produce the dummy. In this way, when the invention is used, it becomes possible to directly print color letters and other things on almost anything, and its practical effects are extremely impressive.
