Abstract

PURPOSE:To obtain a transfer material inexpensive in the running cost capable of using many times by containing heat sensitive fusible ink on a woven cloth of a laminate made of a woven cloth of various fibers and a film of a specific resin. CONSTITUTION:Heat sensitive fusible ink is contained in a cloth of laminate formed of a woven cloth selected from polyester fiber, fluorine fiber, triacetate fiber, glass fiber, carbon fiber, viscous rayon, cotton and silk, and a film selected from a polyester, triacetate and fluorine resin. The cloth used includes warps or wefts of fiber having 80 denier or less to be twisted or both yarns, and preferably 100/2.54cm or larger of warp density, 100/2.54cm or larger of weft density is preferable. This can be used many times to provide inexpensive runing cost.

Description

DETAILED DESCRIPTION OF THE INVENTION The original description relates to a heat-sensitive multiple transfer material.

Conventionally, a resin component, a solid component that is immiscible with the resin component and becomes liquid in a normal vortex and becomes liquid under heat π, and a colorant, as shown in Japanese Patent Publication No. 54-68253 (1), have been used. A composition consisting of a component (hot bath meltable ink) and a volatile bath component that disperses the ink of the solid component and colorant component in a solvent for the resin component is applied to a support and dried. Those containing thermally meltable ink in the pores,
An ink material such as that disclosed in Japanese Patent Application Laid-open No. 56-89984 was mixed with fine powder, and the ink layer was adjusted to wear out gradually starting from the surface layer and used repeatedly.

However, since the durability was only about 10 times, running loss was still high.

The present invention includes polyester fibers, fluorine fibers, triacetate fibers, glass fibers, carbon fibers, viscose rayon,
In a laminate consisting of a woven fabric selected from cotton and silk and a θ) film selected from polyester, triacetate, and fluororesin films, the woven fabric may contain heat-sensitive ink. The inventors have discovered that it is possible to eliminate the above-mentioned drawbacks, create a heat-sensitive multi-transfer material that can be used many times and has a very low running cost, and have completed the present invention.

The woven fabric used in the present invention is polynisdel fiber [
For example, product names: Asahi Kasei Ester (Asahi Hisei), Rikizoe Bou Ester (Kanebo), Cuffre Ester (Kuraray), Tisinbutron (large quantity), Torezotron (Agashi), etc.), fluorine fiber product name, Toyoflon, etc. (East).

Polyflon (Taikin Industries), Palflon (Nippon Palto Industries)], triacetate fibers (e.g., part name: Soalon (Mitsubishi Acetate)), glass fibers (e.g., Asahi Fiberglass, Central Glass, etc.), carbon fibers (e.g., Kureha Chemical, etc.) Nippon Carbon, Azuma et al. are used.

Woven fabrics such as nylon used as ink ribbons have poor heat resistance and durability of the printing surface, and no noticeable effect can be obtained even when used.

The woven fabric used in the present invention preferably uses fibers with a twisting length of 7"L1" and 80"F" or less for the warp, weft, or warp, and has a warp density of 100 fibers. /inch (2,54 crn) or more, latitude density t
A woven fabric constructed with a weave density of 0'0 threads/inch (2,54α) or more has a long lifespan.

However, by using twisted, t'L1, 5-50 annealed fibers for the warp or weft or warp and warp, the warp density is 130-350 pieces/inner (2,54 crn) and the weft density is 110-250 pieces/inch (2,54 crn). The optimal weave density is 54 cm), and when these values are used, (1) the transfer material is resistant to damage, and the printing durability is very good. 7t, the intended multiple printing can sometimes be performed effectively, and (2) the thermally conductive car can print more quickly and clearly.

Examples of the film used in the present invention include the following five films. Examples of polynisual films include Lumirror (manufactured by Toshi) and Diafoil (manufactured by Diafoil ■), and examples of triacetate films include Fushitac (manufactured by Fuji Photo Film).
Examples of fluororesin films include polyvinyl fluoride film and polyvinyl tetrafluoride film, and commercially available products include Polyflon (manufactured by Daikin Industries),
Examples include Teflon (manufactured by Mitsui 70 Rochemical).

Next, the thickness of the above film used in the present invention is 30 μm.
The following is preferable, but better results will be obtained if a value of 10μ to 1μ is used.

The heat-sensitive bath-fusible ink contained in the woven fabric can be a conventional heat-sensitive bath-fusible ink. Further, as a method for incorporating the woven fabric, a composition consisting of a coloring agent, a binder agent, etc. may be applied or immersed in the liquid.

The woven fabric and film do not need to be bonded together, but it is better to bond one side with a thermoset resin or (thermo) crosslinked resin for better thermal conductivity and ease of handling, or to bond the entire surface. is good.

The figure shows a schematic cross-sectional view of one embodiment of the heat-sensitive multiple transfer material of the present invention, which is made by laminating a woven fabric 1 containing a heat-sensitive melting ink and a film 2.

Example 1 Twisted 80 denier polyester fibers, warp density 200 fibers/inch (2,54 tyn), weft density 150
Book/Inner (2.54cm) ” Heat-sensitive bath-fusible ink consisting of a woven fabric woven at 100 degrees, conventionally known color additives, and a wax-based binder. The excess heat-sensitive bath-meltable ink was removed, and the ink was cooled and solidified.

Next, I combined this with a 4μ polyester film [manufactured by "Diafoil" (product name) Tire Foil] and printed it on a P6 printer manufactured by Fujishichi Rocks.
Even if the same 9[ is printed 30 times or more, there is no change in density. Example 2: 50 tenier carbon fiber twisted together @ 1zso
A woven fabric woven with a weave density of 200 threads/inch (2,54 cm ) and a weft density of 200 threads/inch (2,54 L: nl) is coated with a conventionally known coloring agent, a binder agent mainly composed of resin, and an organic bath. When I applied Ra liquid, a heat-sensitive bath-meltable ink consisting of a drying agent, and dried Lf, I combined this with a 4μ polyester film and printed on a Fuji Xerox P6 printer, and the same spot was printed over 30 times. However, there was only one change in concentration.
