Abstract

PROBLEM TO BE SOLVED: To simply form an arbitrary size and a pattern at each of various base materials by adhering a transfer sheet formed with a pattern or the like with an ink containing a sublimable dye through a printer to a base material made of a synthetic resin, and thereafter pressurizing the material while heating. SOLUTION: As a transfer sheet 1, for example, a metal sheet such as an aluminum foil, steel foil or the like, cellophane, plastic sheet or the like is used. As an ink 3 containing a sublimable dye, for example, an ink obtained by kneading a drying oil such as a linseed oil or the like in a varnish made of an alkyd resin or the like modified by the oil or the like is used. A pattern or the like is formed on the sheet 1 by an ink jet printer or an electrostatic printer. Thereafter, the sheet 1 is adhered to a base material (floor material made of a synthetic resin or the like) 2, pressurized at predetermined pressure at a predetermined temperature, the material 2 is impregnated with the ink 3, a clear pattern is transferred, and then the sheet 1 is released to complete its work.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for transferring a printed pattern made of a sublimable dye to a synthetic resin substrate.

[0002]

2. Description of the Related Art Conventionally, a transfer sheet on which a pattern or the like is printed with an ink containing a sublimable dye is superimposed on a synthetic resin and heated to permeate and solidify the sublimated material.
Transfer printing methods for forming dyed patterns are known. However, as a base material, especially, a floor material made of synthetic resin, etc.
There is a problem that a clear pattern cannot be obtained.

[0003]

SUMMARY OF THE INVENTION Therefore, the present invention has been found to provide a method which is simple and capable of performing transfer printing on various substrates.

[0004]

According to the transfer printing method of the present invention, first, a transfer sheet for forming a pattern or the like is formed by a printer or the like using an ink containing a sublimable dye. Then, the transfer sheet is attached to a synthetic resin base material, and is subjected to a pressure treatment under heating, whereby the ink containing the sublimable dye sublimates and is fixed. According to the transfer printing method of the second aspect, printing can be performed more clearly by sandwiching a thin film that can transmit the sublimation ink between the transfer sheet and the synthetic resin base material. According to the transfer printing method of the third aspect, the base material can be prevented from being curved by bringing the form material into close contact with the periphery of the base material.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings.
Metal sheets such as aluminum foil and steel foil, cellophane, plastic sheets, paper coated with synthetic resin on the surface, and the like are used.

The ink 3 containing the sublimable dye is desirably a die-subliminal ink (manufactured by Xerox Corporation of the United States, a specialty toner company of the United States). Alternatively, an ink or the like dispersed or dissolved in a vehicle composed of a binder such as a cellulose derivative such as nitrocellulose, an acrylic resin, and a solvent such as a lower alcohol, a ketone, and water may be used.

Then, a pattern or the like is formed on the transfer sheet 1 using the ink by an ink jet printer or an electrostatic printer. Then, as shown in FIG. 1A, the transfer sheet 1 is used as a base material (a floor material made of synthetic resin (such as vinyl chloride)).
2 、 Temperature 130 ℃ ～ 150 ℃ 、 Pressure 0.7〜
When the transfer sheet is peeled off after maintaining at 1.0 (gauge pressure) for 3 to 5 minutes, the sublimation ink 3 penetrates into the base material 2 and forms a clear pattern. As described above, printing can be favorably performed on a floor material made of vinyl chloride, which cannot be directly drawn in the related art.

Next, as shown in FIG. 1B, as another printing method, the sublimation ink 3 can be transmitted between the transfer sheet 1 and a base material (such as vinyl chloride flooring material) 2. A small hole sandwiches a thin permeable film 5 made of polyethylene or the like. Then, under the same conditions as above, the temperature is 130 ° C. to 150 ° C.
When maintained at a temperature of 0.7 ° C. and a pressure of 0.7 to 1.0 (gauge pressure) for 3 to 5 minutes, the sublimation ink 3 of the transfer sheet 1 penetrates through the permeable film 5 and penetrates the base material 2, Plays a clear pattern. On the other hand, the transparent film 5 adheres to the transfer sheet 1 and peels off, and does not stain the substrate 2.

Next, as shown in FIG. 1C, a frame material such as a phenol resin plate having a different coefficient of thermal expansion from that of the base material is provided around a base material (such as vinyl chloride flooring material) 2. Closely attach 10
Under the same conditions as above, a temperature of 130 ° C to 150 ° C and a pressure of 0.
Printing is performed at 7-1 gauge pressure and maintained for 3-5 minutes. The base material 2 can be prevented from being curved by the high temperature by the mold material 10 and can be finished almost flat.

The base material may be made of another synthetic resin in addition to the floor material made of vinyl chloride. In addition, since an ink jet printer or the like is used, various patterns of black and white and other colors can be easily formed on the transfer sheet, and the size thereof can be easily changed.

[0011]

According to the transfer printing method of the first aspect of the present invention, since the transfer sheet is prepared by using an ink jet printer or the like, the size and the pattern can be easily prepared, and the transfer sheet can be pasted on a synthetic resin base material. After putting on, heat and pressure treatment can be done,
It can be easily manufactured. Further, the transfer printing method according to the second aspect can print more clearly, and the transfer printing method according to the third aspect can prevent the substrate from being curved, thereby improving the finish.
