Description

[0001] The present invention relates to a printing film using a high-resolution coating composition for ink-

The present invention relates to an output film using a coating composition for ink-jet printing, and more particularly, to a coating composition for ink-jet printing, which is produced by mixing micro beads whose surface tension is controlled, anti- And more particularly, to an output film using a coating composition for ink jet printing which reduces the frictional force to improve the scratch resistance and prolongs the life of the rubber roll for feeding.

In the industry, the fabric used as a digital print advertising material is hard-coated on a transparent PVC or PET fabric to protect the surface due to inadequate scratch resistance of the ink layer after printing, and then thermocompressed or pressure- .

This additional process and use of raw materials is a serious cost factor in the production of digital print advertising fabric, and therefore it is necessary to shorten the process and improve the material development.

The anti - blocking characteristic is one of the most important physical properties in fabric production. Anti - blocking characteristics are more important when winding the fabric.

When the anti-blocking characteristic is insufficient, the pressure concentrated at the central portion increases as the load becomes heavy, which increases the possibility of causing sticking between the fabrics.

Advertising fabrics for digital printing use binders with low glass transition temperature because they must contain or function with ink during printing, and in many cases, they cause blocking defects for the same reason in high temperature and high humidity conditions such as summer.

A wide range of digital printing printers used for industrial purposes is expensive equipment costing several tens of millions of won, but has a disadvantage that its service life is not very long compared to its investment cost.

The life span of the printer for digital printing is generally shortened due to abrasion of the feeding rubber roll due to use for a long time.

Large companies such as Hurlpackard, a provider of digital printing printers, are taking a strategy to raise revenue through refilling ink cartridges instead of offering digital printing printers at relatively low prices, which is relatively lukewarm or investment- It is possible to repair by paying the cost.

If a large amount of digital printing advertisement fabric is wound up in a large quantity, blocking is caused by fusion due to the weight of the inner film in the inner core portion, resulting in a large loss.

Also, when inkjet printing is performed, it often occurs that the paper is stuck to the feeding rubber roll or causes friction depending on the room temperature or season, thereby causing defective paper feeding in the printing machine.

In order to solve such problems, the present invention relates to a coating composition for ink-jet printing which comprises mixing micro-beads whose surface tension is controlled, anti-blocking properties by the surface tension of microparticles, And to provide an output film using the coating composition for ink-jet printing which reduces frictional force to improve scratch resistance and prolongs the life of the rubber roll for feeding.

According to an aspect of the present invention, there is provided an output film using a high-resolution coating composition for ink-

And a coating composition for adding 0.5 to 10% of a bead of 5 to 20 micrometers to the binder resin solution,

Characterized in that the coating composition is coated on one side of a substrate layer made of one of transparent, translucent or opaque film to a thickness of 5 to 40 탆.

According to the present invention, by reducing the specific surface area of the output film including the micro-bead whose surface tension is controlled by direct contact with the rubber roll, frictional force is reduced to improve the scratch resistance and prolong the life of the rubber roll for feeding So that a smooth feeding ability is exhibited with low frictional force.

The present invention has excellent scratch resistance, excellent paper feeding ability, and no blocking property by mixing a microbead whose surface tension is controlled on the output film and another specific substance.

The high-resolution coating composition 110 for ink-jet printing according to the first embodiment of the present invention may be prepared by adding a small amount of 0.5 to 10% of 5 to 20 micro-sized beads 112 to the binder resin solution, A coating composition 110 having excellent anti-blocking properties is obtained.

As the binder used in the first embodiment, a resin or a resin mixture composed of a polyester, a polyacrylate, a polyvinyl chloride, a polyvinyl alcohol, a polyethylene vinyl acetate, a polyethylene vinyl alcohol, a polyurethane and a polyvinyl acetate group can be used .

The coating composition 110 thus prepared is coated on the base layer 120 to a thickness of 5 to 40 탆 to produce a high-resolution output film 100 for ink jet printing.

The substrate layer 120 may be made of a polyethylene terephthalate (PET) film but is not limited thereto. Any material such as a polypropylene, a polyacrylic resin, a polyester film, a triacetylcellulose film, a polyethylene film, It is also possible.

The beads 112 of the first embodiment of the present invention described above have particles of 5 to 20 micrometers in size larger than the coating thickness of the binder resin solution.

The beads are formed in an elliptical non-spherical shape, but the present invention is not limited thereto. The beads can be formed in various shapes such as diamond, spherical, grooved, triangular, and rectangular shapes.

Beads are general beads that are widely used, such as paints, pigments, cosmetics, and magnetic coating materials, and are formed of fine particles and include organic beads, inorganic beads, and metallic materials.

The inorganic beads represent a material selected from the group consisting of silica, alumina, calcium carbonate, magnesium carbonate, aluminum hydroxide, titanium dioxide, zirconium oxide and silicone resin. The organic beads include polymethylmethacrylate (PMMA) beads, urea resin Refers to a material selected from the group consisting of powder or poly-condensed plastic powder, PS (polystyrene), polyacrylonitrile (PAN), PBMA (polybutylmethacrylate).

The micro-beads of the second embodiment of the present invention are prepared by mixing micro-beads of two sizes. The micro-beads are composed of a first micro-bead 114 having a larger micro-size than particles mixed with the binder resin solution, And the second microbeads 116 having a nano size are mixed.

The second embodiment is characterized in that the micro-sized bead particles having a size similar to that of the coating film thickness for reducing the contact area to reduce the slip property upon feeding the fabric and improving the scratch resistance after printing, Of bead particles of 1 to 15 microns in size to lower the particle size of the beads.

In the second embodiment of the present invention, when the size and the content of the beads 114 and 116 are appropriately adjusted, the slip property at the time of fabric feeding is controlled, and the scratch resistance and anti-blocking property are improved.

When the polarity groups of the surface are in contact with each other in the blocking mechanism, blocking may occur between the resin coating layer and the film backside due to at least van der Waals bonding, hydrogen bonding or the like

A third embodiment of the present invention is to mix materials 118 of other characteristics in addition to the beads 114, 116 of the second embodiment.

In order to further prevent the blocking property by the chemical structure of the resin solution, an acrylic polymer having a non-polar portion and a reactor (a hydroxyl group, a carboxyl group, etc.) A blocking improver 118 may be additionally used.

The blocking improver is preferably used in an amount of 0.3 to 3.0 parts by weight based on 100 parts by weight of the total solid content. When the blocking improver is used in an amount less than 0.3 parts by weight, sufficient effect can not be exhibited. When the blocking improving agent is used in an amount exceeding 3.0 parts by weight, there is a side effect that a blocking agent is applied to the back surface.

In the third embodiment, in addition to the beads of the second embodiment, a binder resin is formed so as to fix the beads by inter-resin cross-linking so that the bead particles are maintained in a dispersed shape to maintain the air layer coming from the inter-particle gap difference.

The bead fixing binder resin may contain one or more kinds selected from the group consisting of an acrylate resin, a urethane resin, a melamine resin, an ester resin, and a benzene-phenol resin capable of reacting with ultraviolet light at a low voltage of 0.1 to 50 mJ Mixtures may be used.

This third embodiment functions as an anti-blocking layer. In addition to the binder resin, the third embodiment further includes an antistatic agent 118 to prevent running and blocking during a post-processing operation and to prevent static electricity.

Examples of the antistatic agent include phosphoric acid esters, alkyl amine oxides, alkylphosphine oxides, alkyl sulfoxides, alkyl quaternary ammonium halides, alkyl imidazolium halides, at least one selected from the group consisting of halide, alkyl pyridinium halide, alkyl sulfonium halide and alkyl phosphonium halide can be used.

The fourth embodiment of the present invention uses a wax-coated acrylic bead having a similar size but lowering the surface tension instead of the bead of the third embodiment.

That is, the bead of the fourth embodiment mixes a wax-coated first acrylic bead having a size of 5 to 20 micrometers and a second acrylic bead having a wax-coated size of 1 to 15 micrometers smaller than the first acrylic bead.

The output film 100 uses a substrate material having a width of 1200 mm or more in consideration of productivity during the actual coating operation of the paper for a digital printer, and is usually wound up to 2000 to 9000 meters. At this time, the central portion of the rolled roll is subjected to a strong pressure due to the load of the fabric, and accordingly, the anti-blocking characteristic that sticks to the fabrics becomes important, the pressure becomes weaker than the central portion.

In consideration of this characteristic, the bead of the fifth embodiment of the present invention has a first bead 114 having a micro size larger than that of the silica particles mixed with the binder resin solution, and a second bead 114 having a smaller nano size than the first bead 114 The bead 116 includes a micro-sized bead at the center of the output film, and a nano-sized bead is formed toward the outer periphery of the output film.
