Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transfer printing sheet which is novel and has many practical uses.

Conventionally, as a method for printing three-dimensional raised patterns on cloth or sheet-like materials, a method similar to the pigment resin printing method has been used, for example, using a mixture of a resin and a substance that expands the resin film by heating. A pattern that is raised on cloth, etc. by creating a base paste or a mixture of a substance and resin that expands when heated, and then applying ordinary printing, low temperature drying, high temperature drying, etc. It was known to express

Of these two methods, the former is a polymeric resin and a solvent, or a polymeric resin emulsion, which forms a film upon drying and is decomposed by heating to produce a large amount of gas. The resin film is mixed with a substance that expands the volume of the resin film by gas pressure, and the latter mainly uses thermoplastic particles that expand by force heat and resin as an adhesive.

However, in the former case, in order to effectively use the generated gas to expand and bulge the resin film, if the resin film has not already been formed before the knife heating, the loss of gas scattering will be significant, making it difficult to bulge. It is also disadvantageous if the formed film is thin or has micropores, and usually does not rise unless there is a very large amount of solid resin layer.

Therefore, the base glue (: consists of resin components with a high solid content), and as a result, problems such as clogging and gum up during printing operations are likely to occur, and film formation and upheaval are performed in different processes, making it stable. Furthermore, the texture of the raised design portion is extremely poor.

In addition, in the latter case, the source of gas, etc., which causes expansion during heating, is already included in the film, so the loss of such gas, etc. is prevented quite effectively, but as in the former case, in general, Cloth has an uneven surface, which tends to result in uneven printing layers, and the glue paste penetrates into the structure of the material, which has many voids, and expands inside, creating a desired raised design pattern on the surface. More importantly, it is difficult to obtain a raised print that is stable at all times unless the printing, drying, and raising steps are carried out under careful control.

As a result of various studies in order to improve the above-mentioned drawbacks of conventional methods, the present inventors have discovered that a thermally expandable material that can be included on a removable resin layer that covers the entire surface or a portion of a base sheet expands by expansion. A raised resin layer containing a mixture of granules formed of a wall film made of a thermoplastic polymer compound, an elastic polymer resin, and a coloring agent if necessary is printed in a design pattern, and then a raised resin layer is formed on the raised resin layer. A transfer printing sheet obtained by coating the whole structure with a white pigment resin layer containing an elastic polymer resin and a white pigment is applied to an object to be transferred, such as cloth or a sheet-like object, with the surface of the white pigment resin layer. By applying Calorie pressure and heating for a short time, the raised resin layer and white pigment resin layer are melted or softened and transferred to the surface of cloth, etc., and at the same time, the granules also expand, thus creating a stable three-dimensional shape at all times. The target raised pattern appears in one operation, and the elastic polymer resin mixed and contained in the raised resin layer or the white pigment resin layer has thermal crosslinking properties, and the white pigment resin layer or the white pigment resin layer or The inventors have discovered that if the raised resin layer is mixed with a crosslinking catalyst corresponding to the elastic polymer resin having thermal crosslinkability, the crosslinking effect becomes more pronounced, thereby completing the present invention. .

Next, the configuration of the present invention will be specifically explained with reference to the drawings showing one implementation.

Reference numeral 1 denotes a base sheet, which may be made of cellulose paper, synthetic fiber paper, synthetic paper, cellophane, synthetic resin film, etc., and since the printed pattern described below can be seen through the base sheet 1, it may be a transparent sheet or It is desirable to use translucent sheets.

2 is a releasable resin layer coated on the base sheet 1; 3 is a raised resin layer printed in a pattern on the releasable resin layer 2; 4 is a raised resin layer 3. The peelable resin layer 2 is a white pigment resin layer that covers the entire surface, and the peelable resin layer 2 is made of cellulose derivatives such as methyl cellulose and acetyl butyl cellulose, carnauba wax, natural resins such as rosin, polyolefin resins, vinyl resins, It is formed by applying one or a mixture of synthetic resins such as amide resins, silicone resins, and fluororesins onto the base sheet 1 in a solution or molten state over the entire or partial surface of the base sheet 1.

Such a removable resin layer 2 prevents the pigment and resin of the three components of the raised resin layer printed on it in a pattern from penetrating into the base sheet 1, and also prevents the raised resin layer from penetrating into the base sheet 1 during transfer. The effect is to smoothly separate the adhesive resin layer 3 from the adhesive resin layer 3.

Next, the raised resin layer 3 printed in a pattern on the peelable resin layer 2 is a granular resin layer 3 formed of a wall film made of a thermoplastic polymer compound that expands due to the expansion of the thermally expandable material it encapsulates. Printing is mainly composed of a mixture of particles and an elastic polymer resin, and a coloring agent may be added if necessary, and the particulate material and an elastic polymer resin are mixed and contained on the peelable resin layer 2. Using ink, the desired pattern is printed on a plate that is the opposite of that used for normal printing.

Examples of the thermally expandable substances include those that decompose upon heating and generate large amounts of nitrogen, carbon dioxide, etc., such as adupis isobutyronitrino L/, azodicarbonamide, benzene sulfonyl hydrazide, and inorganic substances. Examples include carbonates, etc., or substances that increase in volume through gasification due to heating, such as ether, pentane, hexane, etc., which are included in the wall film made of a thermoplastic polymer compound in advance. However, it is sensitive to short-term pressurization and heating and expands and bulges.
Those in the latter group are preferred.

Examples of the thermoplastic polymer compound include synthetic glues such as polyvinyl methyl ether, polyvinyl alcohol, polyacrylic acid copolymers, and maleic acid copolymers; natural resins or glues such as dammar and ethyl cellulose; Examples include synthetic resins such as polyolefins, polyvinyls, polyacrylic esters, polyurethanes, polycarbonates, natural rubber, synthetic rubber, etc.
These may form a wall film alone or in a mixed state.

They can also be used in monomeric or polymeric form, which can be granulated during polymerization, gelation, and other operations, and can be further crosslinked to increase the strength of the film and more completely shield the expandable substance content from the outside world. can.

These thermoplastic polymer compounds are not particularly limited, but they do not dissolve or expand in thermally expandable substances, are not affected by the solvents that make up the printing ink, and can easily expand. In addition, a material with a small shrinkage rate after expansion is selected, and among the above, synthetic resins are particularly preferred.

The granulation force method for the expandable granules is generally referred to as microencapsulation technology, and a phase separation method, an interfacial polymerization method, a porous rotating tube method, etc. are appropriately adopted, but the granules used in the present invention are Among these, those obtained by interfacial polymerization are recognized as particularly effective.

The obtained granules are (a) Particle diameters must be uniform.

(b) Being stably dispersed in the printing ink (disintegration,
Do not disappear.

). (c) Do not destroy it due to mechanical force during printing operations.

(d) The elastic polymer resin expands sensitively at the same time as it softens or melts.

(e) It is difficult to contract easily after swelling and swelling.

It is preferable to have various conditions such as printing force type and its conditions, pressure and zero force heat conditions during thermal transfer, and the raised effect and fastness of the final product. A 1-40 gravimetric autopsy is used.

Next, the polymeric elastic resin that is mixed with the expandable particulate material to form the raised resin layer 3 is also known as a polymeric elastomer, and the formed film is flexible and has rubber elasticity or similar properties. It has elasticity, and includes vinyl chloride resin, ethylene-vinyl acetate copolymer resin, ethylene-acrylic acid ester copolymer resin, acrylic acid ester resin, chlorosulfonated polyethylene resin, chlorinated polyolefin resin, saturated polyester resin, polyamide resin. You can list the date of the month, etc.

These resins have a melting point or softening point of 50 to 150°C, and are fixed to the transferred material 5 such as cloth or sheet material together with the white pigment resin layer 4 in a molten state or a softened state, and have a flexible feel and are resistant to wind. It functions to maintain fastness to rubbing and fastness to washing without impairing the properties of the coating.

In this case, an elastic polymer resin having thermal crosslinkability is used as the elastic polymer resin in the raised resin layer 3, and
By containing a corresponding crosslinking catalyst in the white pigment resin layer 4, the thermal crosslinkability in the raised resin layer 3 can be improved by partially merging the raised resin layer 3 and the white pigment resin layer 4 during thermal transfer. The elastic polymer resin in the white pigment resin layer 4 contacts the crosslinking catalyst in the white pigment resin layer 4 to generate crosslinks, thereby improving the washing robustness of the transferred material 5 at high temperatures and the fastness to hand rubbing when wet, and It is possible to prevent deformation and loss of bulges in the design due to hot pressing with an iron press, and to improve fastness to dry cleaning.

Here, the polymer elastic resin having thermal crosslinking properties is, for example,
Examples include alkoxymethyl acrylamide copolymer resin, methylol acrylamide copolymer resin, glycidyl methacrylate copolymer resin, and alkoxymethylated nylon resin.

Examples of crosslinking catalysts used include ammonium chloride, zinc nitrate, monoethanolamine hydrochloride, maleic anhydride, dicyandiamide, benzine, boron trifluoride amine complex salt, imidazole, dihydrazide, redulucin, and the like.

Coloring agents that may be mixed in the above-mentioned raised resin layer 3 if necessary include inorganic pigments such as iron oxide, ultramarine blue, carbon black, and titanium white, and organic pigments such as azo thread, anthraquinone thread, and shanine-based pigments. , dye lakes, dye solid solution pigments, metal powders, metallized powders, oil-soluble dyes, disperse dyes, and mixtures thereof.

Incidentally, the raised resin layer 3 contains, in addition to the above-mentioned expandable granules and polymeric elastic resin, a solvent, and if necessary, the above-mentioned colorant, thermosetting resin, plasticizer, surfactant, and stabilizer. A printing ink containing lubricants, ultraviolet absorbers, optical brighteners, viscosity modifiers, oils and fats, etc. is printed on the removable resin layer 2, and then dried to remove volatile substances such as organic solvents and water. Formed by removing matter.

Next, the coated white pigment resin layer 4 contains a mixture of a polymer elastic resin and a white pigment, and the pattern of the raised resin layer 3 on the transferred object 5 penetrates into the structure of the transferred object 5. Therefore, when the transferred material 5 is a colored material, it has the effect of hiding the background color and sharpening the design pattern. This makes it possible to firmly hold the transfer material 5 on the transfer material 5 and to make it easy to realize the thermal transfer and thermal ridges of the transfer printing sheet of the present invention at the same time.

As the elastic polymer resin used for the white pigment resin layer 4, the same resin as the elastic polymer resin used for the raised resin layer 3 is applied, but it is not necessarily necessary to use the same type of resin. Different types of resins may be used as long as they have adhesive properties between the white pigment resin layer 3 and the white pigment resin layer 4.

In this case, if a thermally crosslinkable resin is used as the polymeric elastic resin used in the white pigment resin layer 4 and a corresponding crosslinking catalyst is contained in the raised resin layer 3, The same effect as in the case described above can be obtained in which an elastic polymer resin having thermal crosslinking properties is contained in the resin.

Examples of the white pigment used in the white pigment resin layer 4 include zinc oxide titanium oxide, calcium carbonate, barium sulfate, aluminum silicate, and the like.
Weight capital is used.

The white pigment resin layer 4 is made by adding a thermosetting resin, a plasticizer, a surfactant, a stabilizer, a lubricant, and a viscosity modifier to the printing ink containing the above-mentioned elastic polymer resin, white pigment, and organic solvent, if necessary. It is formed by applying pressure [ ] and printing on the entire surface of the raised resin layer 3 .

The thus obtained transfer printing sheet is heated, for example, at 120 to 220° C., by bringing the white pigment resin layer 4 and the surface of the transfer object 5 into contact with each other, using an iron, a hot press, or the like.
If the base sheet 1 is separated from the transferred object 5 as shown in FIG. 2 by applying pressure and heating for 7 seconds, the transfer and expansion of the raised resin layer 3 will be performed simultaneously, resulting in a three-dimensional shape as shown in FIG. 3. In this way, a printed product with a raised design pattern is obtained.

Transferred object 5 which is the transfer target of the transfer printing sheet according to the present invention
Examples include natural fibers such as cotton, hemp, silk, and wool; recycled or semi-synthetic fibers such as rayon, cupro, polynosic, and acetate; polyamides, polyesters, polyacrylics, polyurethanes, polyolefins, and polyvinyls. Examples include woven fabrics, knitted fabrics, interwoven fabrics, interwoven fabrics, blended fabrics, nonwoven fabrics, etc. made of all kinds of fibers such as synthetic fibers and glass fibers, as well as sheet-like products such as leather, natural rubber, and synthetic rubber.

Note that the surface of the transferred object 5 may be subjected to various processing, or
Even if the sheet is porous, the sheet of the present invention can be used in any case.

Next, the effects of the present invention will be listed.

(1) According to the sheet of the present invention, a constant three-dimensional raised pattern can always be obtained with only one step of pressurization and heating.

(2) According to the sheet of the present invention, by the extremely simple operation of applying pressure and heating, the texture of the transferred object is not impaired.

(3) In the sheet of the present invention, the elastic polymeric resin having thermal crosslinkability and the crosslinking catalyst can be separated between the two layers of the raised resin layer and the white pigment resin layer, so the transfer printing sheet has excellent storage stability. In that case, the transferred raised design pattern is fixed with a polymeric elastic resin in which expanded granules are cross-linked, so the resin will not soften during high-temperature washing, hot pressing, or ironing. or without melting,
The transferred pattern does not fall off from the transferred object or stain other parts.

(4) By using the sheet of the present invention, it is possible to very easily apply three-dimensional raised printing to the desired location of any shape such as a rolled, cut, or sewn product.

(5) When the sheet of the present invention is used, thermally expandable particles, resin, etc. adhere to the surface of the cloth, so the printing pattern can be raised efficiently, and its fastness can be ensured with a relatively small amount of resin. Therefore, its texture is flexible.
