Abstract

A transfer film including a substrate, a protection layer, a metal coating layer, and an ink layer is provided. 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.

Claims15

Dependent claims

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.

3 more elements

A manufacturing method of a transfer film, comprising:

providing a substrate that has a first surface and a second surface opposite to each other, wherein the first surface comprises a first stereoscopic pattern;
forming a protection layer on the first surface of the substrate, wherein the protection layer has a third surface and a fourth surface opposite to each other, wherein the third surface is in contact with the first surface to form a second stereoscopic pattern complementing the first stereoscopic pattern, and the fourth surface comprises a third stereoscopic pattern;
forming a metal coating layer on the fourth surface of the protection layer, wherein the metal coating layer has a fifth surface and a sixth surface opposite to each other, and the fifth surface is in contact with the fourth surface;
and
forming an ink layer 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.
