Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer paper for room temperature printing,

The present invention relates to a transfer sheet for printing at room temperature printing capable of printing using a pressurized press extractor. More particularly, the present invention relates to a transfer sheet for a normal temperature printing using a transfer sheet and a hard thermoplastic resin material (acrylic / PC / PET / ABS / PVC / ) Or soft thermoplastic resin material (PU / TPU / PVC / artificial leather) and natural leather by penetrating and fusing the ultra-thin print layer on the front or back side of the product. High quality, resolution, , Durability, and the like, and relates to a transfer sheet for ordinary temperature printing which does not use heat, fire, water or the like, and a manufacturing method thereof.

Transfer printing refers to transferring a printable image onto a transfer sheet, and then transferring the printable image onto a printed matter to be printed again.

However, a printing method in which a special transfer paper is floated on the water surface by water-mediated water transfer method and presses the printing medium (printing object) can not obtain a printed printed product because the printing form may be diffused before the transfer.

In the case of porcelain printing in the case of the conventional thermal transfer method, after printing on transfer paper, varnish is applied after the ink of the printed material is dried, varnish is applied to the porcelain, and the transfer paper is coated with water before being dried When the transfer paper is peeled off, the pigment is transferred. When the porcelain is baked at a suitable temperature in the baking furnace, the pigment is fused.

However, in the transfer method using water and heat as described above, there is a fear that the printing format may be damaged due to heat or moisture, and the printing process is complicated.

Therefore, in order to overcome such disadvantages, Korean Patent Registration No. 10-0287257 discloses a novel printing composition and a printing method and apparatus using the same.

However, when printed by the printing method described above, the sharpness is degraded, yellowing occurs over time, the printed surface is broken, the printed image is broken, the uniformity is lost, and the partial deviation occurs.

In addition, when a transfer sheet is peeled off, a pinhole phenomenon such as a hole is generated, so that a discontinuous portion is formed in the printed product, and a transfer sheet is stuck and a heterogeneous feeling is generated.

Meanwhile, Korean Patent Publication No. 10-1284511 discloses a novel printing composition, a transfer sheet, and a printed matter and a production using the same, which are configured to be printed at room temperature.

However, there is a problem in that coloring, partial bleaching, bubble, whitening phenomenon, snow flake phenomenon, lack of adhesion, decomposition and dissolution of ink components, change in print color, yellowing, discoloration, generation of static electricity, , Cutting, laser cutting, Thompson processing, etc.), there was a problem that the cutting surface was broken or the cutting surface was cracked.

As a conventional technique, a substrate to be printed using general sheet paper or the like, especially glass, PMMA (polymethylmethacrylate), PC (polycarbonate), PET (polyethylene terephthalate), ABS (acrylonitrile- When it is desired to perform back printing on a TPU (thermoplastic polyurethane), a PVC (polyvinyl chloride), a soft, a hard transparent film or a semi-transparent film or sheet, offset printing using gravure ink, gravure printing Solvent, aqueous dye, and toner. However, after a lapse of time, color bleeding and substrate separation occur, and in the process of degreasing, a phenomenon of separation occurs in the printed matter, bubble phenomenon, And color bleeding phenomenon.

Further, it is known that toxic substances such as toluene, arginine, DMF (dimethylformamide), and DOP (dioctyl phthalate) are used in the process of producing a printing composition using a new printing composition and a transfer- There is a problem.
