Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording sheet and a label, and more particularly to a recording sheet and a label having a cloth-like feel and a metallic luster without curling or cockling.

[0002]

2. Description of the Related Art Ink-jet recording is a method in which minute droplets of ink are made to fly and adhere to a recording sheet such as paper by various operating principles to record images and characters. It has features such as easy multi-coloring, great flexibility in recording patterns, and no need for development-fixing, and is rapidly spreading in various applications as a recording device for various figures including Chinese characters and color images. Furthermore, the image formed by the multi-color inkjet method is
It is possible to obtain a record comparable to multicolor printing by the plate making method. In addition, in applications requiring a small number of copies, it is being widely applied to the field of full-color image recording because of its low cost.

As recording sheets used in the ink jet recording system, efforts have been made in terms of apparatuses and ink compositions in order to use high-quality paper and coated paper used for ordinary printing and writing. However, with the improvement of the performance of ink jet recording apparatuses such as high-speed, high-definition and full-color apparatuses, and expansion of applications, more advanced characteristics are also required for recording sheets.

[0004] That is, the recording sheet has a high density of print dots, a bright and vivid color tone, quick absorption of ink, no ink bleeding or bleeding even when the print dots overlap, High image reproducibility is required such that the diffusion in the horizontal direction is not unnecessarily large and the periphery is smooth and not blurred. It is also necessary to improve the water resistance of an image, which is due to the fact that the ink used for ink jet recording is water-soluble.

[0005] However, in addition to the direction of pursuing high image reproducibility, the direction of using an ink jet recording sheet as a poster or label is also being established. The images used in them are pop art or low resolution photographic images. Rather, the emphasis is on the eye-catching effect, which is more eye-catching than high-definition images.

Means for enhancing the eye catch effect include:
There are large-format, eye-catching coloring. Large format can be realized by increasing the size of the inkjet printer or using a plotter. However, with regard to eye-catching colors, printable colors consist of a combination of cyan, magenta, yellow, and black inks, and it has heretofore been difficult to express colors differentiated from other inkjet printed matter. Accordingly, papers having a glossy print surface so as to be noticeable have been developed. If you look at the glossiness, you will reach a metal foil typified by aluminum foil, but in ink-jet printing, the ink used is often aqueous, the metal foil itself has no solvent absorption, and there is no drying process, so the ink must be used. It was not possible to settle on the surface.

On the other hand, in the fields of design, events, advertisements and the like, color image recording using a durable or water-resistant support and characterized by the texture of the support itself has become widespread. Under such circumstances, various ink jet recording sheets using a cloth as a support have been proposed (Japanese Patent Application Laid-Open No. 02-09-1990).
9677, JP-A-02-219679). But,
In the fields of design, events, advertising, etc., it ’s important to get a lot of attention.
Naturally, there is a limit to eye catching.

As a result of intensive studies, the present inventors have invented a metallic glossy ink-jet paper having a metallic gloss on the recording surface and applied for a patent. In the metallic glossy ink jet recording sheet, since a metal foil is used, even when a cloth is used for the support, a cloth-like texture cannot always be realized.

[0009]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a recording sheet having a metallic luster while maintaining a cloth-like texture and having a high eye-catching effect which can be printed using an ink jet printer. And provide labels.

[0010]

Means for Solving the Problems The present inventors have made intensive studies to solve the above-mentioned problems, and as a result, have reached the following invention.

That is, the invention relates to an ink jet recording sheet in which a fabric, a synthetic resin layer, a metal deposition layer, and an ink receiving layer are laminated.

[0012] Further, the invention is the ink jet recording sheet described above, wherein the back sheet is pseudo-adherable to the opposite surface of the ink receiving layer in a releasable manner.

Further, a cloth, a synthetic resin layer, a metal deposition layer,
An ink jet recording label in which an ink receiving layer is sequentially laminated, and an adhesive layer and a release paper are laminated on a surface of the nonwoven fabric opposite to the ink receiving layer.

Further, the present invention is the above-mentioned ink jet recording sheet or label wherein the synthetic resin layer is laminated with a nonwoven fabric by a hot melt extrusion lamination method.

Further, the invention is the above-mentioned ink jet recording sheet or label, wherein the synthetic resin layer comprises at least one selected from the group consisting of polyethylene, polypropylene and ethylene-vinyl acetate copolymer.

[0016]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A feature of the present invention resides in the metallic glossiness of an ink jet recording surface. In the present invention, a metal vapor-deposited layer is provided to impart a metallic luster to the ink jet recording surface. However, even if a metal vapor deposition layer is provided directly on the surface of the nonwoven fabric, the metallic luster becomes unsatisfactory. Therefore, in the present invention, the synthetic resin layer provided between the nonwoven fabric and the metal deposition layer is essential. Further, by providing the synthetic resin layer with one or more kinds selected from polyethylene, polypropylene and ethylene-vinyl acetate copolymer by a laminating method, the surface retains the texture of the fabric and has a metallic gloss, that is, an eye catch. It turned out that the effect could be raised. Further, although not expected at first, it was found that curling after printing was suppressed, and that cockling of the printing portion did not occur.

The fabric in the present invention refers to a woven fabric, a knitted fabric, and a nonwoven fabric. For woven fabrics, weave fabrics such as plain weave, twill weave, satin weave, and for knitted fabrics, weft knitting such as plain knitting, rubber knitting, pearl knitting, double sided knitting, single tricot knitting, single atlas knitting, single cord knitting, Half tricot knit, plain tricot knit,
Warp knitted fabrics such as queens cord knitting and spelling are used.

The nonwoven fabric is roughly classified into a wet nonwoven fabric, a dry nonwoven fabric by a stitch bond method, a spun bond method, a melt blown method, a thermal bond method, or the like, or a spunlace nonwoven fabric using a wet nonwoven fabric or a dry nonwoven fabric. Preferably, a wet nonwoven fabric or a spunlace nonwoven fabric using the wet nonwoven fabric is more preferably used because of its flexibility.

The fibers constituting the fabric of the present invention include, for example, organic synthetic fibers such as polyester fibers, polyolefin fibers, polyacrylonitrile fibers, polyvinyl alcohol fibers, nylon fibers and urethane fibers, and recycled fibers. Fibers such as fibers, semi-synthetic fibers, and natural fibers are exemplified.

The polyester-based fibers are fibers comprising homopolymers and copolymers such as polyethylene terephthalate, polybutylene terephthalate, and modified polymers of these polymers. What is polyolefin fiber?
Fibers composed of homopolymers and copolymers such as polypropylene, polyethylene, polystyrene, and modified polymers thereof. What is polyacrylonitrile fiber?
Acrylic fiber, modacrylic fiber, etc. The nylon fiber refers to a fiber made of a polymer such as nylon 6, nylon 66, and nylon 12. Semi-synthetic fibers refer to fibers such as acetate fibers. The regenerated fiber is a fiber obtained by spinning a regenerated cellulose fiber such as viscose rayon, polynosic rayon, or lyocell, or a solution of collagen, alginic acid, or chitin. What is natural fiber?
Cellulose fibers such as hemp and cotton, and protein fibers such as wool and silk.

The method of vapor deposition when the metal vapor deposition layer of the present invention is provided is, for example, a method in which a vacuum tank is set to a high vacuum of about 10 ^-4 Torr or more, and then a high purity aluminum, nickel, zinc, copper, silver, gold, etc. In this method, when a metal is heated and melted in a crucible and evaporated, fine metal particles adhere to and aggregate on the synthetic resin layer to form a metal deposition film. Aluminum is preferably used as the metal because of its stability and appearance.

The thickness of the metal deposition film is generally 50 to 5
000 angstroms. If the thickness is less than 50 angstroms, it is difficult to obtain a metallic luster, and if the thickness is more than 5000 angstroms, the adhesion strength to the synthetic resin layer of the present invention tends to decrease, and disadvantages are caused in terms of vapor deposition processing cost.

In the present invention, by providing a synthetic resin layer between the cloth and the metal deposition layer, the metallic glossiness of the ink receiving layer surface can be improved and the eye catching effect can be enhanced. Further, by providing the synthetic resin layer, curl after printing is reduced, and cockling of the printed portion is eliminated.

The provision of the synthetic resin layer improves the metallic luster on the surface of the ink receiving layer when the unevenness on the surface of the metal deposition layer is provided directly on the cloth surface by providing the synthetic resin layer. It is presumed that diffuse reflection on the surface decreases due to further reduction.

The curl reduction after printing and the elimination of cockling in the printed portion are presumed to be due to the increase in rigidity and the suppression of the penetration of the ink solvent into the fabric by providing the synthetic resin layer. .

The method of providing a synthetic resin layer on a cloth in the present invention is as follows: (1) A thermoplastic resin composition is cast on a running cloth by using a hot-melt extruder and cast from a slit die into a film. A so-called hot-melt extrusion laminating method for coating, (2) a so-called film laminating method for laminating a thermoplastic synthetic resin film and a fabric and integrating them by a heat and pressure treatment, or laminating the synthetic resin film to the fabric with an adhesive; (3) A so-called coating method in which a solution or dispersion of a synthetic resin is applied to the surface of a fabric, followed by drying, smoothing, etc. to provide a synthetic resin layer.

Preferably, the synthetic resin layer is coated on the fabric by a hot melt extrusion lamination method. The reason for this is that, in addition to the good adhesiveness to the fabric, fine unevenness derived from fibers on the surface of the fabric is also reflected on the surface of the synthetic resin layer, so that the apparent glossiness is good, and the eye catching property is excellent.
Further, a post-process such as a drying device and a solvent recovery device in the case of using an adhesive is not required, which is preferable in terms of working environment.

In the film lamination method, fine irregularities on the surface of the fabric are hardly reflected on the film surface, so that the surface becomes a smooth flat surface, and the apparent glossiness is inferior to that of the hot melt extrusion lamination method.

In the coating method, in addition to fine irregularities derived from the fibers of the fabric, uneven coating and cracks occur on the coated surface, and even after-treatment such as hot calendering, a uniform surface such as the hot melt extrusion lamination method is used. Is not obtained, and the apparent glossiness is inferior. Operability also increases the number of processes.

In the hot-melt extrusion laminating method, the temperature at the time of hot-melt extrusion is appropriately selected depending on the type of the resin. However, when a heat-fusible fiber is used for the fabric, the softening temperature is higher than the melting temperature. Temperature is preferred. In general,
The temperature for extruding polyolefin is 200-340
° C. As the slit die, a flat die such as a T-type die, an L-type die, or a fishtail type die is preferable, and the slit opening diameter is desirably 0.1 to 2 mm.

Before laminating the thermoplastic resin composition to the fabric, it is preferable to perform an activation treatment such as a corona discharge treatment or a flame treatment in order to improve the adhesion between the fabric and the synthetic resin layer. .

Further, it is preferable to make the surface of the cooling roll used at the time of lamination a mirror surface, since a good metallic luster can be obtained, particularly when a vapor deposition treatment is subsequently performed.

The synthetic resin forming the synthetic resin layer of the present invention includes polyethylene, polypropylene, ethylene-vinyl acetate copolymer, polyvinyl chloride, polyvinyl alcohol, styrene-butadiene copolymer, polyethylene terephthalate, polyacrylonitrile, polystyrene, and the like. Those modified resins and the like are used.

In particular, when a synthetic resin layer is provided by a hot-melt extrusion lamination method, when polyethylene, polypropylene, or ethylene-vinyl acetate copolymer is used as the synthetic resin, it is difficult to delaminate the sheet from a fabric. This is preferable in terms of tactile sensation.

In the synthetic resin layer of the present invention, a copper phthalocyanine-based pigment,
It is also possible to add titanium oxide, cadmium-based pigments, ultramarine blue coloring pigments, dyes and the like for coloring.

The thickness of the synthetic resin layer is not limited, but is generally in the range of 5 to 100 μm, particularly preferably in the range of 10 to 50 μm. If it is thinner than 5 μm, it is difficult to obtain uniform characteristics,
The appearance tends to be uneven. If the thickness is more than 100 μm, the stiffness increases and the texture becomes inferior. In order to reflect subtle irregularities due to fibers on the surface of the fabric, it is preferable that the thickness of the synthetic resin layer is thin, and the thickness is preferably 50 μm or less because the glossiness is excellent.

In the ink jet recording sheet and label of the present invention, when an ink receiving layer is provided on a synthetic resin layer surface of a composite sheet having a synthetic resin layer provided on a fabric (hereinafter, abbreviated as a composite sheet), a corona discharge treatment, Activation treatment such as flame treatment can also be performed.

Or less, more preferably 10 g / m ² or more and 40 g / m ² or less. If the coating amount is less than 5 g / m ² , the ink absorbing ability is reduced and bleeding occurs, and the printing quality is reduced. On the other hand, when the coating amount exceeds 50 g / m ² , the ink receiving component is too thick to cover the composite sheet surface, so that the powder drop of the ink receiving component becomes conspicuous, which also lowers the print quality.

The ink receiving component of the present invention can contain a cationic dye fixing agent. Examples of the cationic dye fixing agent include secondary amines, tertiary amines, and quaternary ammonium salts. These cationic dye fixing agents include a water-soluble direct dye, which is a dye component of an aqueous ink in an ink receiving component, and a water-soluble dye. To form an insoluble salt with the sulfonic acid group, carboxyl group, amino group, etc. in the acidic acid dye, the dye is captured by the ink receiving component, and water is dropped and moisture is absorbed by improving color and forming an insoluble salt. Of the ink and the bleeding of the ink can be suppressed, and the water resistance can be improved.

The adhesive used in the ink receiving component of the present invention includes, for example, polyvinyl alcohol, vinyl acetate, oxidized starch, etherified starch, cellulose derivatives such as carboxymethylcellulose, hydroxyethylcellulose, casein, gelatin, soybean protein. Conjugated diene copolymer latex such as styrene-butadiene copolymer and methyl methacrylate-butadiene copolymer; polymer or copolymer of acrylic acid ester and methacrylic acid ester; acrylic acid and methacrylic acid Acrylic polymer latex such as acid polymer or copolymer; Vinyl polymer latex such as ethylene-vinyl acetate copolymer; or functional group based on functional group-containing monomer such as carboxyl group of these various polymers Modified polymer latte Box; melamine resins, water-based adhesives of thermosetting synthetic resin such as a urea resin; polymethyl methacrylate, polyurethane resin, unsaturated polyester resin,

A back sheet can be quasi-adhered to the surface of the ink jet recording sheet of the present invention opposite to the ink receiving layer. The pseudo-adhesion of the back sheet improves the frictional resistance between the front and back sides of the recording sheet. When performing inkjet printing on the sheet, it does not cause conveyance troubles such as heavy running, skew, etc. Can be realized.

As the back sheet, high quality paper, kraft paper, glassine paper, plastic film, etc. are used.
There is no particular limitation on basis weight, thickness, and the like. As will be described later, there is no problem even if a silicone resin is applied to these back sheets as a release agent, that is, release paper is used.

The means for simulating the adhesion is not particularly limited as long as the back sheet is adhered so that the back sheet can be peeled off after printing. In general, a wet lamination or a dry lamination is carried out using an adhesive. Or a lamination method using a polyolefin resin, or a bonding method using an electron beam-curable resin or an ultraviolet-curable resin.

Further, an ink jet recording label can be obtained by sequentially laminating an adhesive layer and a release paper on the surface opposite to the ink receiving layer of the ink jet recording sheet of the present invention. By adopting this embodiment, the field of application of the ink jet recording sheet of the present invention is expanded, and further, due to the presence of the release paper, it is possible to improve printer transportability, reduce curling, and facilitate handling.

Resins such as polyurethane can be used alone or in the form of a solution, an aqueous solution, or an emulsion. Preferably, a synthetic resin is used. As a method for setting these adhesives, any method such as heat drying and hot melt may be used.

The pressure-sensitive adhesive may be removable. In order for the removable adhesive to function effectively, the adhesiveness (anchoring property) between the fabric and the adhesive is strong, while the cohesive force of the adhesive is strong and the adhesiveness between the adherend and the adhesive is required. Is required. Among these required properties, the dilemma is that the molecular weight of the pressure-sensitive adhesive polymer is preferably low in order to improve the anchoring property, and conversely it is preferable that the molecular weight of the pressure-sensitive adhesive polymer is high in order to satisfy the other two. There is a means for clearing this, for example, a two-component re-peelable pressure-sensitive adhesive. This is to adjust the adhesive force between the pressure-sensitive adhesive and the adherend by securing the anchoring property to the fabric with a low-molecular-weight pressure-sensitive adhesive polymer serving as the main agent, and then crosslinking the polymer with a suitable cross-linking agent to increase the molecular weight. Generally, an acrylic copolymer resin or the like is used as a main agent, and an epoxy resin or the like is used as a cross-linking agent. Alternatively, a functional group that adjusts the adhesive force with the adherend by the physical socket effect of the microsphere adhesive or relaxes the electric coupling between the adherend and the adhesive caused by the surface polarity of the adhesive is used. There is also a method of adjusting the adhesive force by copolymerizing with an adhesive.

Specific one-part adhesives include common acrylic resins, natural and synthetic rubbers, styrene / butadiene copolymers, polyvinyl acetate, vinyl acetate / ethylene copolymers, starch, Silicone compounds,
Resins such as glue, casein, polyvinyl alcohol, polyurethane and polyurethane can be used alone or in the form of a solution, an aqueous solution or an emulsion.

<Test Method> 1) Eye Catch Effect The ink-jet papers obtained in Examples and Comparative Examples were cut to A3 size, and an appropriate image was recorded by an ink-jet printer (Epson PM-5000C). Originally, it is attached to a white background wall and visually observed from a point 10 m away. Those that are distinguished from the whiteness of the wall and whose presence is emphasized are judged to be excellent in eye catch effect, and those that are assimilated to the whiteness of the wall and whose existence is not clear are judged to be poor in eye catching effect.

2) Printer transportability The ink-jet papers prepared in Examples and Comparative Examples were
After cutting to 2 sizes, the sheet was set in 1 inkjet printer (JV2-130 manufactured by Mimaki Engineering) and printed. Printing was performed over 20 sheets, and the number of troubles, such as those that were skewed and those that were not conveyed, were counted. It is best to transport 20 sheets without any problem and the number of troubles is 0, but if the number of troubles is 2 or less, it is judged that there is almost no practical problem. 3) Cockling After cutting the recording sheets prepared in Examples and Comparative Examples to A1 size, 100% of each color of black, cyan, magenta and yellow was printed on the front side by an ink jet printer (JV2-130 manufactured by Mimaki Engineering).

The curl was measured by standing still on a flat desk under an environment of 20 ° C. and a relative humidity of 65%. The curl is represented by the average value of the heights of the lifts at the four corners, the curl is excellent when the average curl is less than 3 mm, and the curl is lined up from 3 mm to 7 mm,
Further curls were judged to be inferior.

[Table 1]

Evaluation: As is clear from the table, the ink jet recording sheet and the label of the present invention are excellent in the eye catch effect due to its metallic luster. However, even if a metal vapor-deposited layer is directly provided on the cloth for Comparative Example 2, the desired glossiness cannot be obtained, and the eye catch effect cannot be improved. In Comparative Examples 1 and 3 having no metal vapor-deposited layer, there is no eye catch effect at all.

Furthermore, in the ink jet recording sheet and label of the present invention, cockling and curling do not occur. In a recording sheet having no synthetic resin layer as in Comparative Examples 1 and 2, cockling occurs and rubbing with the head occurs. Comparative Example 3
It can be seen that in the recording sheet in which only the synthetic resin layer is provided on the cloth as described above, cockling is not eliminated and curling is inferior, probably because there is no metal evaporation layer.

The ink jet recording sheet and label of the present invention have both the texture of the fabric and the metallic luster, and are effective in giving posters, displays and the like a peculiar taste.
