CONSTITUTION:Silicone oil having polyether groups therein is caused to be contained at least in the outermost layer of an image-receiving layer applied to the surface of a paper supporter laminated with film on both sides thereof, so that, when heated, coloring matters are transferred from a thermal transfer color donating material to be received by said image-receving layer to form an image. Polyether denaturated silicone of 0.1-10wt.% of coloring matter receiving polymer which is applied to the image-receiving layer can be used. As a sheet of paper with its both sides being laminated with film, a polyolefin laminate paper can be used. As the polyolefin, there are high-density polyethylene, low-density polyethylene, polypropylene etc., and layer thickness thereof is preferably 5-100mum on one side.

Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a thermal transfer image-receiving material used in a thermal transfer method using a heat-transferable dye. The present invention relates to a thermal transfer image-receiving material with improved handling properties.

(Background technology) In recent years, with the rapid development of the information industry, various information processing systems have been developed, and each information processing system
Suitable recording methods and devices have also been developed and adopted. The thermal transfer recording method is one of these recording methods.The equipment used is lightweight, compact, noiseless, easy to operate,
It has been widely used recently as it has excellent maintainability and can be easily colored. This thermal transfer recording method can be roughly divided into two types: a thermal melting type and a thermal transfer type. In the latter method, a thermal transfer dye-providing material having a dye-providing layer containing pie/goo and a heat-transferable dye on a support is superimposed on a thermal transfer image-receiving material, and heat is applied from the support side of the dye-providing material. A transfer pattern is obtained by transferring the heat-transferable dye to a recording medium (thermal transfer image-receiving material) in the form of a pattern.

Note that the term "thermally transferable dye" as used herein refers to a dye that can be transferred from a thermal transfer dye-providing material to a thermal transfer image-receiving material by sublimation or diffusion in a medium.

(Problems to be Solved by the Invention) Synthetic paper, paper supports, plastic films, etc. are used as supports for thermal transfer image-receiving materials, but among them, polyolefin coated paper (or laminated paper) is prone to concave shapes due to heating during thermal transfer. Due to the deformation of <<, excellent whiteness,
It also has features such as less curling. However, when thermal transfer image-receiving materials made using polyolefin laminated paper are stacked and set in a thermal transfer printer and automatically fed, more than one sheet overlaps and is fed at the same time. It has become clear that there is a problem with paper, which is more likely to cause malfunctions.

(Rounding means for solving the above problems) In order to solve the above problems, the inventors have repeatedly investigated various methods such as adding lubricants, building release agents, and anti-static agents, and found that a certain type of silicone oil I was saddened to discover that it has a remarkable effect on improving paper feeding problems. That is, the above problem is solved by providing at least one image-receiving layer on a paper support laminated with films on both sides to form an image by receiving the dye that migrates from the thermal transfer dye-providing material when heated. The problem has been solved by a thermal transfer image-receiving material characterized in that at least the outermost layer of the surface coated with the image-receiving layer contains a silicone oil containing a polyether group.

Furthermore, it has been found that the polyether-modified silicone oil used in the present invention is highly effective in improving thermal fusion failures that occur when a thermal transfer dye-providing material and a thermal transfer image-receiving material are laminated and heated with a thermal head.

The silicone oil containing a polyether group used in the present invention is represented by the following general formula [1].

The amount of IO'Jl can be used, preferably 0.1 to 1% by weight, particularly preferably /-7% by weight. If it exceeds io% by weight, bleeding of the color image may occur during storage of the transferred print, and thermal fusion with the dye-providing material may be accelerated during thermal transfer.

The paper laminated with film on both sides used in the present invention is described, for example, in "Fundamentals of Photographic Engineering (Silver Salt Photography M)" edited by the Photographic Society of Japan (published by Corona Publishing Co., Ltd., / 7th edition), pages 223-0. One example is polyolefin laminated paper. This polyolefin laminate paper basically consists of a support sheet and a polyolefin layer laminated to the surface of the support sheet. The support sheet must be made of something other than synthetic resin - high-quality paper is used for boat fishing.

The polyolefin laminate may be applied by any method as long as the polyolefin layer is in close contact with the surface of the support sheet, but it is usually applied by an extrusion method.

The polyurethane labanate layer may be provided only on the surface of the support sheet on which the receptor layer is provided, but it may also be provided on both the front and back surfaces.

Polyolefins used include high-density polyethylene, low-density polyethylene, and polypropylene.
Either one may be used. However, in view of the heat insulation effect during transfer, it is preferable to use low-density polyethylene, which has low thermal conductivity, on the side where the receiving layer is provided.

The thickness of the polyolefin layer is not particularly limited, but it is usually preferred that the thickness be 100 μm on one side. However, in order to obtain a high transfer density, it is preferable that the polyolefin layer on the receiving layer side be thin. Pigments and fillers such as rounded titanium oxide and ultramarine blue may be added to the polyolefin layer to increase whiteness. In addition, the polyolefin inolaminated paper has a coating of 0.0j to
A gelatin layer as thin as O9a g /m2 may be provided.

The thermal transfer image-receiving material is provided with an image-receiving layer. This image-receiving layer receives the heat-transferable dye that migrates from the heat-transferable dye-providing material during printing, and is made of a material capable of receiving the heat-transferable dye that has the function of dyeing the heat-transferable dye. Alone or together with other binder materials, the thickness 0.

The high-boiling organic solvent and/or thermal solvent can also be used alone in microdispersed form in the image-receiving layer;
It can also be used in combination with a polymer that can accept heat-transferable dyes.

Further, the above-mentioned high-boiling organic solvents and thermal solvents may be used for the purpose of improving shearability, peelability, curl balance, and the like.

The image receiving layer may be composed of a layer of 2N or more. In that case, the layer closer to the support should be made of a synthetic resin with a low glass transition point, or a high-boiling organic solvent or hot solvent should be used to increase dye dyeing properties, and the outermost layer should have a glass transition point. Avoid sticky surfaces, adhesion to other materials, and reuse on other materials after transfer by using synthetic resins with higher points or by minimizing or not using high-boiling point organic solvents or hot solvents. It is desirable to have a configuration that prevents failures such as transfer and blocking with the thermal transfer dye-providing material.

The total thickness of the image-receiving layer is 0.5 to 50 μm, particularly 3 to 30 μm.
A range of μm is preferred. In case of 2N configuration, the outermost layer is 0.1
The amount is preferably in the range of .about.2 .mu.l, particularly 0.2-1 .mu.m.

The intermediate layer can be a cushion layer, a porous layer, or a
This layer has one of the functions of a dye diffusion prevention layer or a layer having two or more of these functions, and in some cases also serves as an adhesive.

The dye diffusion-preventing layer plays the role of particularly preventing the heat-transferable dye from diffusing into the support. The binder constituting this diffusion prevention layer may be water-soluble or organic solvent-soluble, but preferably a water-soluble binder.
Preferred examples include the water-soluble binders mentioned above as binders for the image-receiving layer, particularly gelatin.

The porous layer is a layer that prevents the heat applied during thermal transfer from diffusing from the image-receiving layer to the support and effectively utilizes the applied heat.

The thermal transfer dye-providing material used in combination with the thermal transfer image-receiving material of the present invention includes a thermal transfer dye-providing material having a layer containing a heat-transferable dye on a support, in which the dye is thermally transferred in a pattern by applying heat.

μ. An undercoat layer may be provided if necessary. Further, a dye diffusion preventing layer made of a hydrophilic polymer may be provided between the support and the dye-donating layer. This further improves the transfer density. As the hydrophilic polymer, the water-soluble polymers described above can be used.

A slipping layer may also be provided to prevent the thermal head from sticking to the dye-donating material. This slipping layer is composed of lubricating substances, such as surfactants, solid or liquid lubricants or mixtures thereof, with or without polymeric binders.

For the dye-providing layer, the dye is selected so that the desired hue can be transferred when printed, and if necessary, 2M with different dyes may be used.
The above dye-providing layers may be formed side by side in one thermal transfer dye-providing material. For example, when printing each color repeatedly according to color separation signals to form an image such as a color photograph, it is desirable that the hues of the print are cyan, magenta, and yellow. Three dye-donor layers containing the dye to be provided are arranged.

Alternatively, a dye-donating layer containing a dye that provides a black hue in addition to cyan, magenta, and yellow may be added. It is preferable to provide a mark for position detection at the same time as the formation of any of the dye-donating layers, since this eliminates the need for an ink or printing process separate from the formation of the dye-donating layer.

Printing was carried out under the conditions of /j~/jmsec, dot density t dots/parallel, and magenta dye was imagewise dyed on the image receiving layer of the thermal transfer image receiving material.

The reflection density of the saturated portion ([)max) of the recorded thermal transfer image-receiving material obtained was measured using a Status A filter, and the results are shown in Table 7.

Further, the recorded thermal transfer image-receiving material obtained was stored in a 6000 incubator for 1 month, and the bleeding of the color was observed. The degree of bleeding was expressed on a scale of A (no bleeding) to D (large bleeding), and the results are shown in Table 1.

Heat fusion with the dye-donating material reduces the output of the thermal head to 20

The adhesion rate of the dye-donor layer was evaluated as 10% or more, 50 to 20% as ×, 0% to 1 as Δ, and no adhesion at all as ○, and the results are shown in the table.

Paper feeding performance in a thermal transfer printer was evaluated as follows.

These results are shown in Table-/.

The results in Table 2 show that polyether-modified silicone oil has a remarkable effect on feeding a large number of sheets.

Furthermore, even if the polyether-modified silicone oil is added, thermal fusion is hardly deteriorated, and as long as the amount added is within io t% of the dye-receiving polymer, the transferred image-receiving material will not be affected during storage. It can be seen that the color image bleeding (bleeding over time) hardly worsens. Furthermore, the amount added is 70% by weight.
Even if this value is exceeded, the bleeding deteriorates slightly over time, but it shows a remarkable improvement effect when feeding a large number of sheets.
