Abstract

PROBLEM TO BE SOLVED: To prevent an inadvertent cutting-out of an image receiving sheet in the case of the sheet is folded and to maintain suitable image receiving performance by penetrating broken line-like perforated lines through the sheet in which an image receiving layer is arranged on a surface of a sheet-like support, and dividing the sheet into a plurality along the perforated lines. SOLUTION: Broken line-like perforated lines penetrating from a front surface to a rear surface of the sublimable thermal transfer image receiving sheet are formed on the sheet, and the sheet is divided into a plurality along the perforated lines. In this case, the perforated lines are set, for example, in a zigzag state, or formed in broken line-like or solid line-like state without zigzag state. That is, the perforated lines are formed suitably in combination by the broken line and the solid line of the zigzag state and the broken line and the solid line without zigzag state. Thus, if the sheet is folded due to a certain reason, the sheet is effectively prevented from being inadvertently cut out, and the sheet is simply cut out when required. Accordingly, image receiving performance of the sheet can be maintained suitably.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sublimation type thermal transfer image receiving sheet for a printer which transfers a sublimable dye by heat to form a dyed image.

[0002]

2. Description of the Related Art In recent years, with the spread of personal computers, VTRs, digital cameras, scanners, and the like as information terminals, the demand for printers that output color images from these still images has been increasing year by year. As a recording method of this full-color printer, there are an electrophotographic method, an ink jet method, a thermal transfer recording method, and the like, and among these, a sublimation type thermal transfer method is sometimes used because a high-definition image such as a photograph can be formed. . This sublimation type thermal transfer system is controlled by an electrical signal such as a laser or a thermal head by bringing an ink ribbon provided with a layer in which a dye which is relatively easily sublimable as a sublimable dye is generally bound with a binder into contact with an image receiving member. The heat energy diffuses and transfers the dye provided on the ink ribbon onto the image receiving body to form an image. At this time, since the sublimable dye is diffused in response to the thermal energy of the laser or thermal head, there is an advantage that the halftone density can be easily obtained and the gradation can be controlled arbitrarily. This is considered the most suitable method.

In order to form high-quality printed images on an image receiving sheet at high speed by using such a thermal printer, it is necessary to provide an image receiving layer on a sheet-like support.
The image receiving layer is composed mainly of a synthetic resin dyeable to a sublimation dye, to which a crosslinking agent, a release agent and the like are added. As the sheet-like support, paper such as coated paper and art paper and various films are used.

In general, the size and size of an image receiving sheet that can be printed by a printer are predetermined. For example, when it is desired to obtain an L-size photograph of an A4 size printer, it is necessary to cut off the image receiving sheet. In addition, since the sublimation type thermal transfer image-receiving sheet is often provided with a resin film layer, it cannot be separated without the above-mentioned processing. That is, after the image is output, it must be cut out using a tool such as scissors or a cutter.

Japanese Patent Application Laid-Open No. 6-127153 proposes that a notch is formed in the image receiving sheet in advance in a dotted line in order to easily cut without using tools such as scissors and a cutter. However, if these cut lines are bent along the cut line when the image receiving sheet is folded and carried, for example, there is a problem that the cut lines are unintentionally cut off. Also, depending on how the cuts are made during printing, the image receiving sheet is easily deformed during printing, and the image forming process of the present invention is characterized by high-definition image output. However, there is a problem that the image is easily affected and an abnormal image is obtained.

[0006]

Therefore, according to the present invention, even if the image receiving sheet is bent for some reason, the image receiving sheet is not unintentionally cut off due to the cut line, and the vicinity of the break during printing is prevented. An object of the present invention is to provide a sublimation type thermal transfer image receiving sheet capable of outputting a high-definition image without deforming the image receiving sheet and causing abnormal image output.

[0007]

Means for Solving the Problems The inventors of the present invention have conducted intensive studies to solve the above-mentioned problems. As a result, the image receiving sheet is folded and carried by providing dashed broken lines zigzag. However, it was found that the image receiving sheet was not unintentionally cut off at the cut line, and the image receiving sheet was not deformed near the break during printing, and the image output did not become abnormal.

Second, in a sublimation type thermal transfer image receiving sheet having a sheet-like support and an image receiving layer formed on the surface thereof and containing a sublimable dye-dyeing resin as a main component, a zigzag penetrating from the front surface to the back surface. Not cut, and a broken cut line provided in a zigzag penetrating from the front surface to the back surface, or a cut line combining them, and divided into two or more portions along these cut lines. The present invention provides a sublimation type thermal transfer image receiving sheet.

Third, in a sublimation type thermal transfer image receiving sheet having a sheet-like support and an image receiving layer formed on the surface thereof and containing a sublimable dye-dyeing resin as a main component, a solid line penetrating from the front surface to the back surface. Has a cutout line in a zigzag shape, a broken line formed in a zigzag penetrating from the front surface to the back surface, or a cut line combining them, and can be divided into two or more portions along these cut lines. The present invention provides a sublimation type thermal transfer image receiving sheet.

Fourthly, in a sublimation type thermal transfer image receiving sheet having a sheet-like support and an image receiving layer formed on the surface thereof and containing a sublimable dyeing resin as a main component, it is not a zigzag penetrating from the front surface to the back surface. It has a dashed cut line, a solid cut line penetrating from the front surface to the back surface, and a dash cut line provided in a zigzag penetrating from the front surface to the back surface, or a cut line combining at least two of them. A sublimation type thermal transfer image receiving sheet is provided which can be divided into two or more portions along these cut lines.

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in more detail. The sublimation type thermal transfer image-receiving sheet of the present invention has a dashed cut line provided in a zigzag penetrating from the front surface to the back surface, and preferably further has a non-zigzag dashed cut line or a solid cut line, It is characterized in that it can be divided into two or more portions along these cut lines.

First, the present invention will be described with reference to the drawings. FIG.
The cut lines of the image receiving sheet according to the first to sixth aspects are shown in FIGS.

FIG. 1 shows a cut line of the image receiving sheet according to the first aspect, and the cut line consists only of a zigzag broken line.

FIG. 2 shows a cut line of the image receiving sheet according to the second aspect, and the cut line is composed of a broken line which is not zigzag and a broken line which is zigzag.

FIG. 3 shows a cut line of the image receiving sheet according to the third aspect, wherein the cut line comprises a solid line and a zigzag broken line.

FIG. 4 shows a cut line of the image receiving sheet according to the fourth aspect, wherein the cut line comprises a non-zigzag broken line, a solid line and a zigzag broken line.

FIG. 5 shows a cut line of the image receiving sheet according to claim 5, wherein the cut line comprises a non-zigzag dashed line, a solid line, and a zigzag dashed line, and the angled portion of the cut line penetrates from the front surface to the back surface. It is a cut line in a shape.

FIG. 6 shows a cut line of the image receiving sheet according to claim 6, wherein the cut line is formed by a solid line and a zigzag broken line, and the cut line is formed by a solid line penetrating the end portion of the image receiving sheet from the front surface to the back surface. It is a cut line.

The image receiving sheet of the present invention (that is, Example 1 described later)
To 7), the cut-out line penetrates from the front surface to the back surface, and the cut-out line is formed in a broken line, and the broken line is provided in a zigzag pattern. Since the sheet is not broken, the image receiving sheet is not unintentionally cut off. In addition, cutting can be performed without using tools such as scissors and cutters.

Further, by providing a non-zigzag dashed cut line or a solid cut line, it is possible to reduce the number of irregularities in the cut and improve the appearance. Furthermore, the angled portion of the cutout line is apt to be erroneously torn in a direction other than the direction to be cut when cutting after printing, but by providing a solid cutout line in this portion, the image receiving sheet can be cut cleanly. Further, when the cut line reaches the end of the image receiving sheet, the cut line near the end is formed as a solid cut line penetrating from the front surface to the back surface, so that the cut line can be easily cut. Also,
If a so-called half-cut is performed on the portion provided with the cutout line from the back surface to the middle of the image receiving sheet, it becomes easier to separate the image receiving sheet.

If the length of the portion that does not penetrate between the portion penetrated by the broken line and the next portion penetrates, if it is too long, the unevenness increases after cutting off, and the dot breaks during printing, and Since a shift occurs, it is necessary to make the length appropriate. If it is less than 50 μm, it will be torn during printing, and if it exceeds 1 mm, unevenness will be noticeable.
m is good.

The cut line on the dashed line used in the present invention is used for general perforation processing, micro perforation processing, and the like.
Any processing method may be used.

The sheet-like base material used for the image receiving sheet of the present invention is a sheet-like sheet of 10 to 1000 μm such as paper or synthetic resin. Conventionally used paper such as synthetic paper and plain paper made of natural fibers is used. As the synthetic paper, various stretched films and various nonwoven fabrics in which synthetic fibers are bound with an adhesive are used.For plain paper, high quality paper, medium quality paper, coated paper, art paper, cast coated paper, Processed paper impregnated with or coated with a synthetic resin or rubber or internally added can be used. The film may be a transparent film, various colored films, or the like.

The sheet-like substrate may be provided with an intermediate layer such as a hollow particle layer or a hollow film between the image receiving layer. The hollow particle layer imparts cushioning and heat insulating properties to the image receiving sheet or the image receiving body, and the relative speed of the recording medium to the image receiving body is 1 / n times (n> 1) (that is, the speed of the image receiving body is recorded). Even when heating and printing from the substrate side of the recording body (at a speed higher than the speed of the body), density unevenness due to paper formation can be prevented. In the sublimation type thermal transfer printing of the present invention, the hollow particle layer of the paper substrate is dispersed in a resin solution or a resin dispersion that does not dissolve and break the hollow particles, and is coated on the paper by various coating methods. Obtained by:

The diameter of the hollow particles in the hollow particle layer is 0.2 μm.
The thickness is preferably 30 μm or less, and if it is less than 0.2 μm, sufficient cushioning properties and heat insulation properties cannot be obtained, so that density unevenness corresponding to formation cannot be prevented. If it exceeds 30 μm, the image quality becomes white and deteriorates due to unevenness of the surface due to particles. In particular, 1 μm or more and 15
Hollow particles having a diameter of not more than μm are preferable because sufficient cushioning properties and heat insulating properties can be obtained and a flat coating film can be easily obtained. The volume hollow ratio of the hollow particles needs to be 50% or more. If the volume hollow ratio is less than 50%, sufficient cushioning properties and heat insulating properties cannot be obtained.

Hollow particles are generally difficult to handle because of their low specific gravity. Therefore, it is preferable to use hollow particles coated with an inorganic pigment because the specific gravity becomes high and the handling becomes easy. Examples of the inorganic pigment for coating the hollow particles include calcium carbonate, talc, titanium oxide, and the like, and these are coated on the hollow particles by heat fusion or the like. The hollow particles are preferably obtained by microencapsulating a low-boiling liquid such as butane or pentane with a resin or copolymer such as polyvinylidene chloride, polyacrylonitrile, or methyl methacrylate. There are pre-expanded hollow particles and unexpanded hollow particles, but unexpanded hollow particles are difficult to foam uniformly with heat at the time of printing and do not result in a uniform image. The image is better when used. As a resin that binds hollow particles,
A resin such as a general thermoplastic or thermosetting resin is used.A water-soluble resin such as polyvinyl alcohol is used as a solvent for water, a resin insoluble in water is used as an emulsion, or a resin is dissolved in an organic solvent. Or use it.

When it is desired to prevent the hollow particles from dissolving and breaking when coating the upper image receiving layer or the like, the binder resin of the hollow particle layer should be a resin that does not dissolve in the above-mentioned coating solution. . The content of the hollow particles in the hollow particle layer is 10% to
Preferably it is 90%. If it is less than 10%, sufficient cushioning and heat insulation cannot be obtained. Further, even if it exceeds 90%, no clear improvement is seen in the cushioning property and the heat insulating property, and it is particularly preferably 20% to 80%. The application of the intermediate layer containing the foamed particles can be performed by a method such as roll coating, bar coating, gravure coating, gravure reverse coating, etc. In particular, in the case of die coating, a uniform coating film can be obtained.

As the image-receiving layer which can be dyed with a dye, various thermoplastic resins or thermosetting resins are used. For example, vinyl acetate resin, polyester resin, polyvinyl chloride resin, vinyl chloride-vinyl acetate copolymer, cellulose ester Resin, epoxy resin, polyvinyl butyral resin, polyurethane resin, polyacrylate resin, polymethacrylate resin, polycarbonate resin, polyvinyl alcohol resin, polystyrene resin, polyetherimide resin, polyamide resin, polyethylene oxide resin, polyvinyl ether resin or Any known thermoplastic resin such as a polyacrylonitrile resin can be used, and a reaction-cured product with a cross-linking agent, or a mixture of two or more thereof may be used. In particular, the polyvinyl acetal resin forms a high-density image and has good image storability.

The thickness of the dyeing layer is preferably about 1 to 20 μm, particularly preferably 1 to 10 μm. In addition, a lubricant can be added to increase lubricity, and if necessary, a curing agent, a filler, a surfactant, an ultraviolet absorber, an antioxidant, an optical brightener, a curing reaction accelerating catalyst, etc. are known. May be added. These materials are dissolved in an appropriate organic solvent, applied on a foamed layer of the base film by an optional coating machine such as a roll coater, a bar coater, a gravure coater, a die coater, and dried to form an image receiving layer. If a reaction system material is used, such as when a curing agent is used, or if the solvent is likely to remain, aging is further performed at an appropriate temperature to carry out the reaction sufficiently or reduce the residual solvent to reduce the storage stability. It needs to be improved.

By providing a release layer on the resin layer, fusion or sticking of the image receiving layer and the recording layer hardly occurs. In particular, since the foamed particle-containing layer has low heat resistance and low mechanical strength, it is considered that if the runnability is improved by the release layer, the load on the foamed layer is reduced, and sticking becomes very advantageous. The release layer may be a conventionally known resin as long as it is a resin having a release property, for example, a silicone resin. Further, by adding a lubricating substance, it becomes even better. For example, petroleum lubricating oils such as liquid paraffin, halogenated hydrocarbons, diester oils, silicone oils, synthetic lubricating oils such as fluorosilicone, and various modified silicone oils (epoxy-modified, amino-modified) , Alkyl-modified, polyether-modified, etc.), silicone-based lubricating substances or silicone copolymers such as copolymers of organic compounds such as polyoxyalkylene glycol and silicon, silicone copolymers, fluoroalkyl compounds and other fluorine-based surfactants, trifluoro Fluorinated lubricating substances such as ethylene chloride low polymer, waxes such as paraffin wax and polyethylene wax, higher fatty alcohols, higher fatty acid amides, higher fatty acid esters, higher fatty acid salts, molybdenum disulfide and the like can be used. In particular, silicone copolymer (resin Silicon those formed by block- or graft-copolymerization) is good. These lubricating substances may be used alone or in combination of two or more. The thickness of the release layer is 0.05 μm to 10
It is preferably about μm.

As known additives, ultraviolet absorbers, antioxidants, light stabilizers and the like may be added. In addition, by performing a heat treatment after the image is formed, the dye transferred to the image receiving body is diffused inside, and storage stability, plasticizer resistance, and light resistance are improved. These heat treatments may be performed once, but are further improved by performing the heat treatments twice or more. These materials are dissolved in an appropriate organic solvent, applied on a foamed layer of the base film by an optional coating machine such as a roll coater, a bar coater, a gravure coater, a die coater, and dried to form an image receiving layer. If a reaction system material is used, such as when a curing agent is used, or if the solvent is likely to remain, aging is further performed at an appropriate temperature to carry out the reaction sufficiently or reduce the residual solvent to reduce the storage stability. It needs to be improved.

A back layer can be provided on the lower surface of the sheet-like support by using a conventionally known material, or can be subjected to surface treatment, heat and energy treatment.

In the recording method used in combination with the image receiving sheet of the present invention, the relative speed of the recording medium to the image receiving sheet is 1 / n times (n> 1) (that is, the speed of the image receiving sheet is smaller than the speed of the recording medium). By performing heating printing from the substrate side of the recording medium (at a higher speed), the running cost can be reduced.
