[0005]

A new problem which has not been a problem when a heat roll is used as a heating means when a resin layer on a transfer sheet is thermally transferred onto an image receiving body is a problem when a thermal head is used. Occurs. That is, in the case of a hot roll, when at least one of the stacked transfer sheets and the image receiving body is pressed and passed between two rolls that are hot rolls (rollers with a built-in heater), both rolls are rotating rolls. Therefore, in the case of a thermal head, since one of the thermal heads under pressure and the platen roll is a non-rotating member, the transfer sheet running on the thermal head side is used. However, there is a problem that it cannot run stably.
In other words, the transfer head has sufficient running lubricity and heat resistance against the amount of heat generated by the thermal head when transferring the resin layer of the transfer sheet onto the image receiving member. A transfer sheet that runs stably without causing running scratches or the like during running on a resin layer or the like transferred onto the body has not been obtained.

It is.

The base material has at least a lubricating heat-resistant layer on one side and a laminate of a resin layer and a dye diffusion preventing layer on the other side, and a release layer, a resin layer and a dye layer on the base material. A sequential laminate with a diffusion preventing layer, a sequential laminate of a release layer, a resin layer, a dye diffusion preventing layer and an adhesive layer on a substrate, a sequential laminate of a dye diffusion preventing layer and a resin layer on a substrate, a substrate A layered product of a colored layer and a resin layer on top, or a layered product of a release layer, a resin layer and a colored layer on a base material, etc. can also be constructed.

The substrate 1 is not particularly limited. For example, polyethylene terephthalate (PET), polyethylene naphthalate, aramid, triacetyl cellulose, polyparabanic acid, polysulfone, polypropylene, cellophane,
Each film of moisture-proof cellophane or polyethylene is useful. The thickness of the substrate is not particularly limited. Normal 3
Films of １００100 μm are useful.

The resin layer 2 is made of at least a resin. Either a thermoplastic resin or a thermosetting resin can be used. For example, vinyl resins, urethane resins, acrylic resins, amide resins, ester resins, cellulose resins, epoxy resins, phenol resins, phenoxy resins, silicone resins, and the like can be used. Specifically, vinyl chloride resin, vinyl chloride copolymer (for example,
Binary copolymers such as vinyl chloride-vinyl acetate resin, vinyl chloride-acrylate resin, ternary copolymers such as vinyl chloride-vinyl acetate-vinyl alcohol resin, etc.), chlorinated vinyl chloride resin, methyl (or Ethyl) methacrylate resin, acrylic polyol resin, acrylic copolymer (eg, acrylonitrile-styrene resin, acrylonitrile-butadiene-styrene resin, etc.), polycarbonate resin, saturated polyester resin, polystyrene resin, polyvinyl acetal resin (polyvinyl formal, polyvinyl butyral) Phenoxy resin, urethane resin, alkyd resin, modified alkyd resin (phenol modified, vinyl modified, etc.), epoxy resin, xylene formaldehyde resin, polyamide resin, phenol resin,
Cellulose resins (ethyl cellulose, ethyl hydroxyethyl cellulose, etc.), silicone resins (silicone resins, acryl-modified silicone resins, epoxy-modified silicone resins, etc.), terpene resins and the like. The thickness of the resin layer is not particularly limited. Usually, it is used in the range of 0.3 to 50 μm.

The lubricating heat-resistant layer 3 is constituted by using at least a hydroxyl group-containing resin, a thermoplastic resin, an adhesive, a lubricant and a cross-linking agent. To form a crosslinked structure. The heat-resistant lubricating layer 3 is constituted by using a hydroxyl group-containing resin, a thermoplastic resin, a lubricant and a crosslinking agent, wherein the thermoplastic resin has a heat deformation temperature or a glass transition temperature of 70 ° C. or more, and And the hydroxyl group-containing resin may form a crosslinked structure by a reaction with a crosslinking agent in the slippery heat-resistant layer.

The hydroxyl group-containing resin is not particularly limited as long as it has a hydroxyl group (OH group) in the molecule. For example, acrylic polyol, polyester polyol, polyether polyol, polyurethane polyol, polycarbonate diol, epoxy-modified polyol, polyvinyl acetal resin, and the like can be used.

In the present application, the hydroxyl group-containing resin is
Since it is used in combination with a thermoplastic resin, a resin having a particularly large OH value is desirable so that the addition of the thermoplastic resin does not lower the heat resistance of the entire lubricating heat-resistant layer. For example, a resin having at least an OH value (hydroxyl value) of 10 (mgKOH / g) or more is particularly desirable as the hydroxyl group-containing resin. Particularly good is an OH value of 50 (mg KO).
H / g) or more. Regarding the slipperiness of the thermal head with respect to the thermal head in high-speed recording or high-energy recording, it is effective that the lubricating heat-resistant layer does not easily undergo thermal deformation even in high-speed recording or high-energy recording. When a hydroxyl group-containing resin having a high point is used, a lubricating heat-resistant layer having excellent lubricating properties can be formed. Particularly, a hydroxyl group-containing resin having a Tg of 30 ° C. or more is preferable.

The thermoplastic resin used for the lubricating heat-resistant layer 3 is preferably a resin having a heat deformation temperature or a glass transition temperature of 70 ° C. or more. If at least one of the heat deformation temperature and the glass transition temperature is 70 ° C. or more, it falls within the category of the thermoplastic resin of the present application. The heat distortion temperature was determined by the test method of the American Society for Testing Materials (ASTM, D648, load standard: 18).
20 kPa).

The lubricating heat-resistant layer having a cross-linked structure composed of a hydroxyl group-containing resin, a cross-linking agent, and a lubricant causes a problem that a fine line is generated on the resin layer 2 or the like as a transfer layer when running on a thermal head. There is. As a result of examining this problem by further adding various thermoplastic resins to this system,
It has been found that a resin having a lower heat distortion temperature has a smaller fine line prevention property as a resin has a lower heat deformation temperature, and a resin having a higher heat deformation temperature has a superior fine line prevention characteristic. That is, the heat distortion temperature is 7
When a resin having a temperature of 0 ° C. or higher was used, the fine wire preventing property was improved, and a resin having a heat deformation temperature of 80 ° C. or higher was particularly excellent.
When the thermal head is running, fine running flaws (a factor that causes fine lines on the resin layer 2 or the like as a transfer layer) due to a fine running flaw on the surface of the lubricating heat-resistant layer film are easily caused by the hydroxyl group-containing resin and the crosslinking agent. The film strength of the cured product itself is not very high, and it is considered that the film strength is reduced by the addition of a lubricant, or the degree of cross-linking of the film surface is not sufficient. By adding a high resin, running scratches on the film surface are remarkably improved. Similarly, by using a resin having a glass transition temperature of 70 ° C. or more, the generation of fine wires can be remarkably improved.

It is considered that the transfer sheet and the image receiving body run under the pressing condition applied between the thermal head and the platen roll, and the transfer sheet is caused by uneven pressing when running on the thermal head. Resin with high heat deformation temperature or glass transition temperature against running scratches on the surface of the lubricating heat-resistant layer usually has high film strength due to large molecular weight, and has moderate flexibility when heated compared to cured products. It is considered that the film has sufficient film strength and flexibility to absorb uneven pressing.

The heat deformation temperature or glass transition temperature is 70 ° C.
As the above resin, for example, acrylonitrile-styrene resin, polystyrene, acrylonitrile-butadiene-
There are a styrene resin, a methacrylic resin, a phenoxy resin, a vinyl chloride resin, a chlorinated vinyl chloride resin and the like, and a high molecular weight resin is particularly useful. Particularly, acrylonitrile-styrene resin, methacrylic resin, and phenoxy resin are useful, and resins having a heat deformation temperature of 80 ° C. or more are particularly excellent in preventing fine wires.

The heat deformation temperature or glass transition temperature is 70 ° C.
As described above, examples of the thermoplastic resin containing a hydroxyl group include phenoxy resins, polyvinyl acetal resins, and cellulose resins (various cellulose derivatives and the like). Since these resins also have an OH group, by reacting with a crosslinking agent, the adhesive strength to a substrate such as a PET film is improved. In particular, phenoxy resin is a resin having a high molecular weight and excellent heat resistance, and at least a resin falling within the category of a thermoplastic resin. The adhesive strength to the base material is improved, and the phenoxy resin itself has excellent properties for preventing fine wires due to its hard and ductile properties.

The crosslinking agent is not particularly limited as long as it chemically reacts with the hydroxyl group-containing resin. For example, there are an isocyanate compound, a dialdehyde compound, a phenol resin, a melamine resin, and an epoxy resin. As the isocyanate compound, for example, tolylene diisocyanate,
Hexamethylene diisocyanate, polyisocyanate obtained by reacting 1 mol of trimethylolpropane with 3 mol of tolylene diisocyanate, and the like. The mixing ratio of the crosslinking agent to the hydroxyl group-containing resin is not particularly limited. Usually, a compounding ratio in which the amount of the OH group, which is the reactive group of the hydroxyl group-containing resin, and the amount of the reactive group of the crosslinking agent are equivalent is used. For example, (OH group amount of the hydroxyl group-containing resin / reactive group amount of the crosslinking agent) = (10/1)-(1
/ 4).

It is even better if the slippery heat-resistant layer contains an adhesive. That is, when the lubricating heat-resistant layer is composed of a hydroxyl group-containing resin, a thermoplastic resin, a lubricant and a cross-linking agent, the thermoplastic resin having a high heat distortion temperature or Tg does not have a very large adhesive strength to the base material. It is desirable to add an adhesive. The adhesive has a function of increasing at least the adhesive strength between the thermoplastic resin and the base material. The adhesive is preferably a resin having a heat deformation temperature or Tg lower than the heat deformation temperature or Tg of the thermoplastic resin used for the lubricating heat-resistant layer. The addition of the adhesive prevents peeling of the thermoplastic resin from the base material, particularly, peeling during heating. As the adhesive, for example, saturated polyester resin, urethane resin, polyester urethane resin and the like are preferable.

It is even better if the lubricating heat-resistant layer contains a damage inhibitor. Various silicone-modified resins, various fluorine-modified resins, and the like can be used as the damage inhibitor. As the silicone-modified resin, for example, various silicone graft copolymers (including a multi- or more-component copolymer) such as a silicone-graft acrylic resin, a silicone-graft polyester resin, and a silicone-graft polyurethane resin can be used. For example, a silicone graft polymer [trade name: SYMAC, Toa Gosei Chemical Industry Co., Ltd.], a silicone graft acrylic resin [article number: X
-22-8004, X-22-8909, X-22-8
053, X-22-8015, X-22-8084, X
-22-8019, X-22-8033, X-22-8
095X, etc., Shin-Etsu Chemical Co., Ltd.] silicone-acrylic copolymer [trade name: Dycalak, product number: 5600,
Daido Chemical Co., Ltd.]. Examples of the fluorine-modified resin include a fluorine-modified resin having a perfluoroalkyl group. Particularly useful as a damage inhibitor are various silicone-modified resins, and these resins can impart lubricity to the surface of the lubricating heat-resistant layer, so that the amount of the liquid lubricant useful as a lubricant is relatively small. can do.

Since the damage inhibitor is a solid resin having a binder function, it does not cause much reduction in the film strength of the surface of the lubricating heat-resistant layer as compared with the addition of a liquid lubricant, Since it is a resin having lubricity, even if added in a small amount, it exhibits a property that a function of preventing damage is easily added to the surface of the slippery heat-resistant layer. In other words, the damage inhibitor is a resin having a large amount of silicone and thus having a small film-forming ability as a single resin because of the addition of silicone or the like, so that it is difficult to use, but together with a hydroxyl group-containing resin having high film strength and a thermoplastic resin, It can be considered that the use of such a resin makes it possible to strongly hold the resin in the resin matrix, and since it is a resin having lubricity, it has a large effect of preventing the thermal head from being damaged on the surface of the lubricating heat-resistant layer. From the above, the higher the Tg of the damage inhibitor, the better, and those with a Tg of 50 ° C. or more are particularly good. In particular, when a resin having low heat resistance such as an adhesive is added to the slippery heat-resistant layer, it is preferable to use a combination of a damage inhibitor having a Tg higher than the Tg of the adhesive.

The lubricant is not particularly limited. For example, dimethyl silicone oil, phenyl methyl silicone oil,
Silicone oils such as fluorosilicone oil, various modified silicone oils (epoxy-modified, amino-modified, carboxyl-modified, polyether-modified, alcohol-modified, alkyl-modified, amide-modified, SiH-modified, silanol-modified, alkoxy-modified, etc.), monoglyceride stearate, Fatty acid esters such as stearyl stearate and pentaerythritol tetrastearate, fatty acid amides such as caproic acid amide, various surface lubricants and the like can be used.

The interfacial lubricant is described, for example, in JP-A-59-196.
No. 291 can be used. In particular, the phosphate ester-based lubricant is lubricated or /
It is desirable because it has excellent antistatic properties. For example, phosphanol (product name: RS-410, RS-71)
0, RL-210, RD-510Y, GB-520, Toho Chemical Industry Co., Ltd.). The surfactant is effective in reducing running noise and running frictional resistance due to static electricity generated when the transfer sheet runs on the recording head.

It is even better to use a combination of a reactive silicone oil and a non-reactive silicone oil as a lubricant. That is, by using the reactive silicone oil, the amount of the non-reactive silicone oil to be added can be relatively reduced. For example, liquid reactive silicone oils have a small effect on the heat resistance of the lubricating heat-resistant layer due to solidification or increase in molecular weight due to the formation of a reactant. This makes it difficult for silicone oil to diffuse and transfer to the transfer layer side such as the resin layer 2 which is in contact with the heat-resistant heat-resistant layer. For example, as the reactive silicone oil, a reactive silicone oil having the same reactive group can be used by reacting via a catalyst or the like, or a reactive silicone oil having a reactive group that reacts with each other can be used in combination. it can.
For example, an epoxy-modified silicone oil and an amino-modified silicone oil are used as an interactive silicone oil, and a dimethyl silicone oil is used as a non-reactive silicone oil. A cured product and dimethyl silicone oil can be contained. In addition, a reactive silicone oil having a reactivity with a hydroxyl group-containing resin, a thermoplastic resin, or a crosslinking agent can be used. For example, each modified silicone oil (epoxy-modified, amino-modified, alcohol-modified, etc.) can be used alone or in combination. Non-reactive silicone oils having a small molecular weight tend to diffuse and transfer to the resin layer side during winding storage, whereas those having a high molecular weight are less likely to undergo diffusion transfer.

A polysiloxane-polyoxyalkylene block copolymer having a structural unit represented by the following general formula (Formula 1) is useful because it can be used as a high molecular weight lubricant. As a lubricant, Japanese Patent Application No. 8-33788
The polysiloxane-polyoxyalkylene block copolymer described in No. 6 can be used.

Since the heat-resistant lubricating layer 3 has a cross-linked structure formed by the reaction of the hydroxyl group-containing resin with the cross-linking agent, it has good winding preservability.

The lubricating heat-resistant layer 3 can contain fine particles. Also, a conductive agent such as carbon black may be contained in the lubricating heat-resistant layer to be used as a conductive layer for a current-carrying recording head.

As the fine particles, organic fine particles and inorganic fine particles can be used. For example, JP-A-60-82385, JP-A-60-219094, and JP-A-2-808
No. 7, No. 5-16548, No. 5-17796
The fine particles described in Japanese Patent Publication No. 2 and the like are useful. Examples include synthetic amorphous silica, carbon black, alumina, titanium oxide, talc, calcium carbonate, silicone-based particles, fluorine-based particles, graphite, molybdenum disulfide, and the like.
In particular, synthetic amorphous silica, talc, and silicone-based particles are preferable. Ultrafine particles having an average primary particle diameter of 0.5 μm or less have an effect of preventing the lubricating heat-resistant layer from being scraped off by the recording head and removing adhering substances when dust or resin adheres to the recording head. This is particularly useful because of its excellent (cleaning) properties.

The thickness of the lubricating heat-resistant layer is not particularly limited.
Usually, it is used in a range of 0.01 μm to 5 μm.

The mixing ratio of the thermoplastic resin to the hydroxyl group-containing resin is not particularly limited, but usually, the amount of the thermoplastic resin is 8 to 20 to 95 parts by weight of the hydroxyl group-containing resin.
It is used in the range of 0 to 5 parts by weight.

The mixing ratio of the lubricant to the total amount of the hydroxyl group-containing resin and the thermoplastic resin is not particularly limited.
Used in the range of parts by weight or less.

The compounding ratio of the adhesive to the thermoplastic resin is as follows:
Although not particularly limited, the adhesive is usually used in an amount of 100 parts by weight or less based on 100 parts by weight of the thermoplastic resin.

The compounding ratio of the damage inhibitor to the total amount of the hydroxyl group-containing resin and the thermoplastic resin is not particularly limited, but is usually in the range of 100 parts by weight or less for the total amount of the resin. Used in.

The mixing ratio of the fine particles to the total amount of the hydroxyl group-containing resin and the thermoplastic resin is not particularly limited, but usually the fine particle amount is used in the range of 50 parts by weight or less based on 100 parts by weight of the total resin. .

The release layer 4 has a function of facilitating peeling of the transferred material from the release layer when transferring the transferred material (the resin layer 2 or the like) on the release layer to an image receiving body or the like. The material of the release layer 4 is not particularly limited as long as the transferred material (the resin layer 2 or the like) on the release layer can be peeled from the release layer 4. For example,
Various types of curable resins using heat, light, electron beams, or the like, a configuration including a release agent and a thermoplastic resin, or a configuration including a release agent and various types of curable resins can be used. For example, as a resin, various silicone resins (condensation reaction type, addition reaction type, peroxide curing type, ultraviolet curing type, etc.), acrylate curing type resins (polyester acrylate, epoxy acrylate, urethane acrylate, silicone acrylate, etc.), hydroxyl group-containing Resin (acrylic polyol,
Examples of release agents such as polyester polyols) include various silicone oils, various modified silicone oils, fluororesins, and various surfactants.

The heat-resistant protective layer 5 has a role of protecting the substrate 1 from heat. For example, when a sublimation type ink sheet and a transfer sheet are combined and a thermal head is heated from the ink sheet side to form a sublimation transfer image on the resin layer 2 of the transfer sheet, particularly high density recording (high energy recording) is performed. In such a case, the heat from the thermal head reaches the base material of the transfer sheet, causing a problem that the base material is thermally deformed (eg, thermally contracted). Therefore, a heat-resistant protective layer 5 is provided to prevent thermal deformation of the substrate. When a full-color image is formed on the resin layer of the transfer sheet, usually three colors of yellow, magenta and cyan are sequentially recorded. However, if the base material shrinks when the first color is recorded, the second color is recorded. This is because the dot position of the recording of the second color does not overlap the dot position of the first color, and the dot position shift occurs, which causes deterioration of the image quality. As a material of the heat-resistant protective layer 5, a thermoplastic resin or a thermosetting resin can be used. For example, a combination of a hydroxyl group-containing resin and a polyisocyanate, or an ultraviolet-curable or electron-beam-curable acrylate-based curable resin (such as the polyester acrylate described in the release layer 4) is preferable.

When the resin layer 2 on the transfer sheet is transferred from the transfer sheet onto the image receiving member, the adhesive layer 6 is provided on the resin layer 2 so that the image forming member of the resin layer 2 is formed by the adhesive layer 6. Adhesiveness to the resin layer 2 with low energy
Can be transferred to an image receiving body, and thus has a function of enhancing the adhesiveness of the resin layer 2 and facilitating the transfer. The adhesive layer 6 is preferably made of a thermoplastic resin, such as a saturated polyester resin, an ethylene-vinyl acetate copolymer, or a vinyl chloride resin (vinyl chloride, a vinyl chloride-acrylate copolymer, a vinyl chloride-ethylene copolymer). Etc.), polyvinyl acetal-based resins (eg, polyvinyl butyral), terpene-based resins, and the like.

The dye diffusion preventing layer 7 has a function of preventing the dye recorded on the resin layer 2 from diffusing and moving to the adhesive layer 6 or the image receiving member. As the resin of the dye diffusion preventing layer, a resin having a glass transition point higher than that of the resin of the resin layer 2 or a resin having lower dyeability than the resin layer 2 is preferable. The resin for the dye diffusion preventing layer can be selected from the resins described in the resin layer 2 and used. Further, resins having low dyeing properties such as polyethylene resins and silicone-containing resins can be used.

The coloring layer 8 exists on the other surface of the resin layer on which an image is recorded on one surface, and the coloring layer can be visually observed from the resin layer side through the transparent resin layer. By providing a colored surface on the back of the image for the image, it has a function of giving each color a coloring effect on the back of the recorded image.

The colored layer 8 is white or of each color. For example, a resin layer containing a white pigment or a colored pigment, or a vapor-deposited film (or a sputtered film) of a metal, various compounds, or the like is used. Titanium oxide, barium sulfate, aluminum oxide, silica, calcium carbonate and the like can be used as white pigments, and phthalocyanine, quinacridone and azo pigments can be used as colored pigments. In addition, various dyes can be used as a coloring agent. As the resin of the coloring layer 8, for example, various resins described in the resin layer 2 can be used.

Also, aluminum, as a material for the deposited film, etc.
Materials that can form a thin film, such as gold, silver, copper, and nickel, can be used.
