Abstract

Provided is matte film including: a film layer that is formed in a nano-web shape by electrospinning a polymer material; an ink layer that is coated on one surface of the film layer; and an adhesive layer that is laminated on the other surface of the film layer through electrospinning. Since the film layer is formed in a nano-web shape so that fiber strands are accumulated, the matte film can be thinly produced and have a non-glossy function of performing scattered reflection of light and a fingerprint-preventive function of making fingerprints imprinted. Further, the surface strength of the matte film can be reinforced.

First claim

The invention claimed is:

1. A matte film comprising:
a film layer that is formed of nano-web of fiber strands made by a spinning method of a polymer material, the polymer material of the film layer being selected from the group consisting of polyvinylidene fluoride (PVDF), poly (vinylidene fluoride-co-hexafluoropropylene), perfluoropolymer, polyvinyl chloride, polyvinylidene chloride, copolymers of polyvinyl chloride or polyvinylidene, a polyethylene glycol derivative comprising polyethylene glycol dialkyl ether and polyethylene glycol dialkyl ester, poly-oxide comprising poly (oxymethylene-oligo-oxyethylene), polyethylene oxide and polypropylene oxide, polyvinyl acetate, poly(vinylpyrrolidone-vinyl acetate), polystyrene and polystyrene acrylonitrile copolymer, polyacrylonitrile copolymer comprising polyacrylonitrile methyl methacrylate copolymer, polymethyl methacrylate, polymethyl methacrylate copolymer, and mixtures thereof;
an ink layer that is coated on one surface of the film layer; and
an adhesive layer that is laminated on the other surface of the film layer through an electrospinning process.

2. The matte film of claim 1 , wherein the spinning method is any one of electrospinning, air-electrospinning (AES), electrospray, electrobrown spinning, centrifugal electrospinning, and flash-electrospinning.

3. The matte film of claim 1 , wherein irregular unevenness is formed on the surface of the film layer and thus the film layer has a non-glossy function of performing scattered reflection of light and a fingerprint-preventive function of making fingerprints imprinted.

4. The matte film of claim 1 , wherein the ink layer is formed by mixing an ink, a binder, and a solvent, in which the ink is made of a black or color.

5. The matte film of claim 1 , wherein the ink layer is coated on the outer surfaces of the fiber strands so as to be coated at points where the fiber strands cross each other to thus reinforce strength of the fiber strands.

6. The matte film of claim 1 , wherein the adhesive layer is formed by spinning an adhesive material of a viscosity suitable for spinning, by an electrospinning method, in which the adhesive material is made of a mixture of an adhesive and a solvent.

7. The matte film of claim 1 , wherein the adhesive layer comprises a first adhesive layer formed on the film layer; and a second adhesive layer formed on the first adhesive layer, and wherein the first adhesive layer has a relatively higher viscosity than the second adhesive layer.

8. The matte film of claim 1 , further comprising: a non-pore film layer formed between the film layer and the adhesive layer.

9. The matte film of claim 8 , wherein the non-pore film layer is formed in a non-porous shape by spinning a polymer material containing PU (Polyurethane) or TPU (Thermoplastic polyurethane).

10. A matte film comprising:
a film layer that is formed of nano-web of fiber strands made by a spinning method of a polymer material;
an ink layer that is coated on one surface of the film layer; and
an adhesive layer that is laminated on the other surface of the film layer through an electrospinning process, wherein the adhesive layer comprises a first adhesive layer formed on the film layer; and a second adhesive layer formed on the first adhesive layer, and wherein the first adhesive layer has a relatively higher viscosity than the second adhesive layer.

11. A matte film comprising:
a film layer that is formed of nano-web of fiber strands made by a spinning method of a polymer material;
an ink layer that is coated on one surface of the film layer;
an adhesive layer that is laminated on the other surface of the film layer through an electrospinning process; and
a non-pore film layer formed between the film layer and the adhesive layer.
