Abstract

An abrasion-resistant transfer printing structure to transfer patterns and texts to a targeted object surface by press printing includes a hardened protecting layer and a release base layer. The hardened protection layer includes a first surface and a second surface. The first surface allows a transfer printing glue to be bonded to the targeted object to cover at least an area corresponding to the patterns and texts. The release base layer is located on the second surface of the hardened protection layer by a releasable manner and can be separated from the hardened protection layer by applying a release force after the press printing process is finished. Thus the hardened protection layer is exposed to isolate the patterns and texts from in contact with the exterior. The surface of the targeted object also is abrasion resistant.

Claims (26)

1. An abrasion-resistant transfer printing structure for transferring patterns and texts to a targeted object surface by press printing, comprising:

a hardened protection layer including a first surface and a second surface, the first surface allowing a transfer printing glue to be bonded to the targeted object to cover at least a selected area matching the patterns and texts; and

a release base layer which is located on the second surface of the hardened protection layer by a releasable manner and separable from the hardened protection layer through a release force after the press printing is finished;

wherein the hardened protection layer is exposed after the release base layer is separated to isolate the patterns and texts from in contact with exterior and provide abrasion resistance for the targeted object surface;

wherein the release base layer is integrally formed in one body and includes a release material; and

wherein the release base layer is selected from the group consisting of polyethylene terephthalate, polyethylene napthalate, polyethylene glycol-co-cyclohexane-1,4-dimethanol terephthalate, thermalplastic polyurethane, polyurethane, polypropylene, polycarbonate, amorphous polyethylene terephthalate and polyvinyl chloride and combinations thereof.

2. The abrasion-resistant transfer printing structure of claim 1 , wherein the hardened protection layer has a hardness of F or higher based on pencil hardness test measurement of JIS K 5400.

3. The abrasion-resistant transfer printing structure of claim 1 , wherein the hardened protection layer produces no scraping traces by adopting a RCA standard of applying 175 g of pressure for at least 300 times.

4. The abrasion-resistant transfer printing structure of claim 1 , wherein the hardened protection layer is formed at a thickness between 3-100 μm.

5. The abrasion-resistant transfer printing structure of claim 1 , wherein the hardened protection layer is formed at a desired thickness between 4-30 μm.

6. The abrasion-resistant transfer printing structure of claim 1 , wherein the transfer printing glue has an activated temperature between 80° C.-250° C.

7. The abrasion-resistant transfer printing structure of claim 1 , wherein the transfer printing glue contains a leveling agent.

8. The abrasion-resistant transfer printing structure of claim 1 , wherein the release base layer is a composite base film consisting of a main base layer and a sub-base layer, the main base layer being selected from the group consisting of polyethylene terephthalate, amorphous polyethylene terephthalate and polyethylene napthalate; the sub-base layer being selected from the group consisting of polyethylene glycol-co-cyclohexane-1,4-dimethanol terephthalate, thermalplastic polyurethane, polyurethane, polypropylene, polycarbonate, amorphous polyethylene terephthalate and polyvinyl chloride.

9. The abrasion-resistant transfer printing structure of claim 1 , wherein an effective temperature of the releasable manner is between 50° C.-300° C.

10. The abrasion-resistant transfer printing structure of claim 1 , wherein the transfer printing glue is selected from the group consisting of hot melt glue, UV glue, light activated glue and electronic beam activated glue and combinations thereof.

11. The abrasion-resistant transfer printing structure for transferring patterns and texts to a targeted object surface by press printing, comprising:

a hardened protection layer including a first surface and a second surface, the first surface allowing a transfer printing glue to be bonded to the targeted object to cover at least a selected area matching the patterns and texts; and

a release base layer which is located on the second surface of the hardened protection layer by a releasable manner and separable from the hardened protection layer through a release force after the press printing is finished;

wherein the hardened protection layer is exposed after the release base layer is separated to isolate the patterns and texts from in contact with exterior and provide abrasion resistance for the targeted object surface;

wherein the release base layer has a release film in contact with the second surface and a base film located on the release film; and

wherein the base film is selected from the group consisting of polyethylene terephthalate, polyethylene napthalate, polyethylene glycol-co-cyclohexane-1,4-dimethanol terephthalate, thermalplastic polyurethane, polyurethane, polypropylene, polycarbonate, amorphous polyethylene terephthalate and polyvinyl chloride and combinations thereof.

12. The abrasion-resistant transfer printing structure of claim 11 , wherein the base film is a composite base film consisting of a main base layer and a sub-base layer, the main base layer being selected from the group consisting of polyethylene terephthalate, amorphous polyethylene terephthalate and polyethylene napthalate; the sub-base layer being selected from the group consisting of polyethylene glycol-co-cyclohexane-1,4-dimethanol terephthalate, thermalplastic polyurethane, polyurethane, polypropylene, polycarbonate, amorphous polyethylene terephthalate and polyvinyl chloride.

13. The abrasion-resistant transfer printing structure of claim 11 , wherein the effective temperature of the releasable manner is between 50° C.-300° C.

14. The abrasion-resistant transfer printing structure of claim 1 , wherein the patterns and texts are formed on an ink layer located on the first surface of the hardened protection layer.

15. The abrasion-resistant transfer printing structure of claim 14 , wherein the ink layer is formed by ink selected from the group consisting of ink of a sublimation type, a heat-transfer type and an UV type.

16. The abrasion-resistant transfer printing structure of claim 14 , wherein the ink layer selectively further includes a photo mask layer, a metal evaporation layer, a sputtered layer or a pearl luster material layer.
