The substrate has a first surface and a second surface, and the first surface has a first stereoscopic pattern. The protection layer is disposed on the substrate, and has a third surface and a fourth surface. The third surface contacts the first surface, and has a second stereoscopic pattern complementing the first stereoscopic pattern. The fourth surface has a third stereoscopic pattern. The metal coating layer is disposed on the protection layer, and has a fifth surface contacting the fourth surface and a sixth surface. The ink layer is disposed on the metal coating layer. The protection layer and the substrate are separated after transfer to expose the second stereoscopic pattern and reflect out the third stereoscopic pattern. A manufacturing method of the transfer film is also provided. ## Claims ### Claim 1 A transfer film, comprising: a substrate, having a first surface and a second surface opposite to each other, wherein the first surface comprises a first stereoscopic pattern; a protection layer, disposed on the first surface of the substrate and having a third surface and a fourth surface opposite to each other, wherein the third surface is in contact with the first surface and comprises a second stereoscopic pattern complementing the first stereoscopic pattern, and the fourth surface comprises a third stereoscopic pattern; a metal coating layer, disposed on the fourth surface of the protection layer and having a fifth surface and a sixth surface opposite to each other, wherein the fifth surface is in contact with the fourth surface; and an ink layer, disposed on the sixth surface of the metal coating layer, wherein the protection layer and the substrate are separated after transfer, so as to expose the second stereoscopic pattern and reflect out the third stereoscopic pattern, wherein a geometrical contour of the second stereoscopic pattern is different from a geometrical contour of the third stereoscopic pattern. ### Claim 2 (depends on 1) The transfer film according to claim 1, further comprising: an adhesive layer, disposed on the ink layer, wherein the metal coating layer and the adhesive layer are respectively located on two opposite sides of the ink layer. ### Claim 3 (depends on 1) The transfer film according to claim 1, wherein the fifth surface comprises a fourth stereoscopic pattern complementing the third stereoscopic pattern, and the sixth surface comprises a fifth stereoscopic pattern that is conformal with the fourth stereoscopic pattern. ### Claim 4 (depends on 3) The transfer film according to claim 3, wherein the ink layer has a seventh surface that is in contact with the sixth surface, and the seventh surface comprises a sixth stereoscopic pattern complementing the fifth stereoscopic pattern. ### Claim 5 (depends on 1) The transfer film according to claim 1, wherein the protection layer is a transparent protection layer configured to allow a light to pass through and reflect out the light that reaches a junction between the fourth surface and the fifth surface. ### Claim 6 (depends on 1) The transfer film according to claim 1, wherein the metal coating layer is a translucent metal coating layer. ### Claim 7 (depends on 6) The transfer film according to claim 6, wherein a light transmittance of the metal coating layer is in a range of 30% to 80%.
