[Related Art] In recent years, a thermal transfer sheet is heated by a thermal head or the like in which heat generation is controlled by an electric signal, and dyes in a color material layer of the thermal transfer sheet are transferred onto a thermal transfer sheet to perform recording according to image information. The thermal transfer recording method has attracted attention because an image such as a photograph can be easily obtained directly from an electric signal. A conventional thermal transfer sheet used in the thermal transfer recording system generally includes a sheet substrate and a receiving layer provided on the substrate and capable of receiving a dye transferred from the thermal transfer sheet. The image receiving layer of this type of heat transfer sheet mainly uses a polyester resin or the like as a material for forming the image receiving layer, and dissolves or disperses this resin material in a solvent and prints, coats, or the like on the sheet substrate. Is formed by coating. [Problems to be Solved by the Invention] However, the conventional heat-transferred sheet has poor surface smoothness, so the transferred image is rough and lacks sharpness, and the image receiving layer is formed using a polyester resin or the like. Although the dyeing properties of the dyes are good, the transferred images are blurred due to migration of the dyes during the preservation of the sheet after the transfer recording, or the images themselves are faded, and the images after the transfer are transferred. There was a problem that storage stability was poor. Further, the image receiving layer formed by using a polyester resin or the like is usually formed by coating an ink made of a polyester resin on a sheet substrate, and in particular, a heat transfer sheet including the image receiving layer is used as an OHP sheet or the like. If
Although it is necessary to make the image receiving layer thick, there is a problem in that the image receiving layer itself has no cushioning property and flexibility, and the image density is low, which causes problems in practical use. [Means for solving the problems] In view of the above problems, the present inventors have conducted intensive studies,
Polyvinyl chloride as the main component, while adding ethylene-vinyl acetate copolymer as a polymer plasticizer,
A heat transfer sheet having an image receiving layer formed using a resin composition to which at least one plasticizer other than an ethylene-vinyl acetate copolymer is added has excellent surface smoothness, and can transfer and record a clear image. It has been found that the image transfer stability is good, and that the heat transfer sheet can be configured as a simple structure that does not necessarily require the sheet substrate, which is a necessary component of the conventional heat transfer sheet, The present invention has been completed. That is, the present invention provides (1) a heat-receiving sheet having an image receiving layer for receiving a dye transferred from the thermal transfer sheet when heated, wherein an ethylene-vinyl acetate copolymer is added as a polymer plasticizer; The image receiving layer is formed of a resin composition containing polyvinyl chloride as a main component to which at least one other plasticizer is added in addition to the ethylene-vinyl acetate copolymer, and the image receiving layer is peeled off on the back surface side. A heat transfer sheet, wherein a release member is formed by providing a support member via an adhesive layer so that the adhesive does not remain on the release surface on the image receiving layer side, and (2) the image receiving layer is formed as a film. The heat transfer sheet according to claim 1, which is a film-formed film,
(3) The heat-transferable sheet according to claim 1 or 2, wherein a plasticizer is added to the resin composition containing polyvinyl chloride as a main component in an amount of 5 to 60% by weight. The heat transfer sheet according to any one of claims 1 to 3, wherein a heat releasing agent is added to a resin composition as a component. Embodiment An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the heat transfer sheet of the present invention comprises an image receiving layer 1 and a support member 3 provided on the back side of the image receiving layer 1 via a weak adhesive layer 8 to form a release layer 4. It is of a configuration. The image receiving layer 1 is formed by using a resin composition containing polyvinyl chloride as a main component. The resin composition containing polyvinyl chloride as a main component refers to a resin composition containing 50% by weight or more of polyvinyl chloride, and specific examples thereof include a homopolymer of only polyvinyl chloride; A copolymer obtained by copolymerizing 5 to 20% of vinylidene chloride, acrylate or the like; and a mixed resin obtained by blending polyvinyl chloride with another resin such as ethylene-vinyl acetate. In the present invention, an ethylene-vinyl acetate copolymer is added as a polymer plasticizer to the resin composition containing polyvinyl chloride as a main component, and at least one other type of ethylene-vinyl acetate copolymer is used. Add plasticizer. Plasticizers other than the ethylene-vinyl acetate copolymer include phthalic esters such as di-n-alkyl phthalate and diisoalkyl phthalate; dibasic esters such as dioctyl adipate and dibutyl sebacate; tricresyl phosphate And the like. Inorganic acid esters such as, for example, glycol esters and polyhydric alcohol esters; fatty acid esters; epoxy resin acid esters which also function as stabilizers. By adding these plasticizers, the flexibility of the image receiving layer 1 can be improved, and as a result, the image receiving layer can be rich in cushioning property and can record an image corresponding to image information with little noise and with good reproducibility. it can. In particular, by adding an ethylene-vinyl acetate copolymer as a polymer plasticizer,
There is an advantage that the effect of preventing bleeding of a transferred image is enhanced. The plasticizer can be added to the resin composition containing polyvinyl chloride as a main component in an amount of 5 to 60% by weight, preferably 10 to 60% by weight. If the amount of the plasticizer is less than 5% by weight, the image receiving layer becomes hard and the dyeing property of the dye at the time of transfer is reduced.
When the amount is more than 10% by weight, although the dyeing property of the image receiving layer to the dye is greatly improved, bleeding of the image with the passage of time is apt to occur, and the long term storability of the image is poor. In forming the image receiving layer 1, an ethylene-vinyl acetate copolymer was added as a polymeric plasticizer as described above, and one or more other plasticizers other than the ethylene-vinyl acetate copolymer were added. It is preferable that a film is formed by a casting method (solution casting method) or a calendar method using a resin composition containing polyvinyl chloride as a main component to form a film. If the image receiving layer in the present invention is formed into a film by processing the film in advance, the image receiving layer can be easily obtained only by the film forming process. There is also. Specifically, a residual solvent expelling step, which is necessary in the production of a conventional heat transfer sheet formed by coating and forming an image receiving layer on a sheet substrate, causes a release agent (such as silicone) to float on the surface of the image receiving layer. A so-called thermal curing step or the like, which is followed by heating and curing, is not required. The image receiving layer 1 can be easily obtained in various thicknesses, and the thickness is 5 to 300 μm, preferably 50 to 200 μm.
It is. Further, a heat releasing agent may be added to the resin composition used for forming the image receiving layer 1 as needed.
The imparting agent at least exhibits a releasability function at least when heated, and by adding this imparting agent, the image receiving layer surface is thermally fused to the thermal transfer sheet by heating a thermal head or the like during transfer recording. It is possible to perform good separation from the thermal transfer sheet. Examples of the heat releasing agent include paraffin, polyethylene wax, higher fatty acid, fatty acid amide, fatty acid ester, metal soap, phosphoric acid ester, silicone oil and the like, and the addition amount is preferably 10% by weight or less. In the present invention, the release layer 4 is provided on the back side of the image receiving layer 1 so that the adhesive does not remain on the release surface on the image receiving layer 1 side after the release. The heat-transferable sheet of the present invention can be suitably used as a heat-transfer sheet for producing a transmission type original, and the transmission type original creation sheet is transparent itself at the stage of being mounted on a projector such as an OHP after transfer recording. However, in order to improve the running property in the printer during transfer, for example, as shown in FIG. The support member 3 may be provided between the image receiving layer 1 and the weak adhesive layer 8 after image transfer, and used after removing the image. The support 3 may be transparent or opaque, but if it has transparency, the white coat layer 2 is formed on the lower surface of the support 3.
May be provided. Further, as shown in FIG. 1B, a transparent reinforcing material 9 may be provided in order to have the strength of the image receiving layer 1 used as a transmission type original sheet, and the reinforcing material 9 is made of polyethylene. A transparent film such as a terephthalate film is provided on the back surface of the image receiving layer 1 via an adhesive layer. In the heat transfer sheet shown in FIGS. 1A and 1B, the lower surface of the image receiving layer 1 (see FIG.
Alternatively, a release layer can be provided on the lower surface (B in the same figure) of the reinforcing member 9. The heat transfer sheet of the present invention is white and can be easily peeled off from the image receiving layer in the form of a film in order to make it easy to confirm the transferred image recorded on the image receiving layer 1 as shown in FIG. A certain release coat layer 10 may be provided as the release layer 4. As described above, the heat transfer sheet of the present invention can be used even when the support material 3 or the release coating layer 10 is provided as the release layer 4 on the back surface side of the image receiving layer 1 when these release layers 4 are released after image transfer. Since the adhesive does not remain on the back surface of the image receiving layer 1, it is suitably used as an OHP sheet. The heat transfer sheet of the present invention has an antistatic property on the image receiving layer, the support material 3 and the peeling layer such as the peelable coat layer 10 in order to make the sliding of the sheets smoother and to prevent the heat transfer sheet from adhering dust and the like. Material can be included. It is also possible to provide a detection mark on the heat transfer sheet of the present invention. The detection mark is extremely convenient when positioning the heat transfer sheet and the heat transfer target sheet.
A detection mark that can be detected by the photoelectric tube detection device can be provided on the back surface of the sheet or the like by printing or the like. The heat-transferred sheet of the present invention having the above-described configuration is superimposed on the heat-transfer sheet so that the color material layer of the heat-transfer sheet and the receptor layer of the heat-transfer sheet come into contact with each other, and heated by a thermal head or the like from the support material side of the heat-transfer sheet. Then, the dye of the color material layer is transferred to the image receiving layer by peeling off the thermal transfer sheet, whereby an image corresponding to the image information is recorded on the thermal transfer sheet. [Effects of the Invention] As described above, the heat-transferred sheet of the present invention includes an ethylene-vinyl acetate copolymer as a polymer plasticizer, and one or more other types of ethylene-vinyl acetate copolymers. By forming the image receiving layer using a resin composition containing polyvinyl chloride as a main component to which a plasticizer is added, the image receiving layer can be compared with a conventional heat transfer sheet in which the image receiving layer is formed using a polyester resin or the like. Because of its excellent surface smoothness and elasticity, it is possible to record a clear transfer image with high density without roughness. In addition, the dye is excellent in dyeing properties, the transferred image is hardly blurred or faded with time, and the image storage stability is excellent. Further, since the image receiving layer can be formed as a film, there is an effect that it is not necessary to remove the residual solvent in the coating layer (image receiving layer) in the manufacturing process. Further, by adding a plasticizer, the flexibility of the image receiving layer can be improved, and as a result, the image receiving layer can be rich in cushioning property and can record an image corresponding to image information with little noise with good reproducibility. In particular, by adding an ethylene-vinyl acetate copolymer as a polymer plasticizer, the effect of preventing bleeding of a transferred image can be enhanced. Furthermore, in the heat transfer sheet of the present invention, since a support member is provided on the back surface of the image receiving layer via a weak adhesive layer so that the adhesive does not remain on the release surface on the image receiving layer side after peeling, the release layer is formed. The thermal transfer sheet has good running properties in a printer and does not leave a weak adhesive on the image receiving layer side even when the release layer is peeled off after image transfer, so that it is suitably used as an OHP sheet.
