Abstract

An ultra-thin color film manufacturing method and its product comprises of the following steps: providing a bottom film, an adhesive, an ultra-thin transparent film, and a pigment. The thickness of the bottom film lies between 30[mu]m~50[mu]m. The thickness of the ultra-thin transparent film is between 6[mu]m~8[mu]m. After baking the adhesive to achieve the semi-drying state by coating the adhesive on one surface of the ultra-thin transparent film, the bottom film and the ultra-thin transparent film are rolled to paste both as a one. The pigment is coated and colored on the other surface of the ultra-thin transparent film to perform secondary baking process so that the pigment is fixated on the ultra-thin transparent film, and the finished product is stored into a roll. Accordingly, the bottom film is used as a support structure during baking process to prevent the ultra-thin transparent film from being deformed or generating wrinkles during baking process; and moreover, it can also be taken as protection purpose for subsequent processing.

Description

Ultra-thin color film manufacturing method and finished product thereof

The present invention belongs to the field of manufacturing three-dimensional graphic decorative sheets containing metal components, and particularly relates to an ultra-thin color film manufacturing method and a finished product thereof which are applied to the three-dimensional graphic decorative sheet to change the original color and highlight the three-dimensional decorative effect.

According to the various sheet-like decorations previously announced in the Patent Database of the Republic of China, such as No. 351670, "The Method of Making New Ornaments for the Front Cover of Shoe Body", No. 351073, "The New Ornamental Structure of the Front Cover of the Shoe Body" In the second case, the decoration for attaching to the surface of the shoe is revealed. Because of the flat printing effect, the three-dimensional pattern effect cannot be exhibited, and although it does not detract from its aesthetics, it is limited by the flat representation ability and cannot be more beautiful. Decorative effect.

Therefore, the "Method for Forming a Three-dimensional Marker" No. 403639 has been disclosed, which discloses a three-dimensional marker which can exhibit a three-dimensional pattern effect, but in the production, a flat pattern must be printed on a sheet before use. A zinc plate of the same pattern is embossed to produce a corresponding three-dimensional texture on the plate. Since the pattern must be accurately aligned, the pattern can be corresponding to the three-dimensional texture, and the formed three-dimensional pattern is exposed to the outside, and is easily subjected to abrasion and oxidation. In addition, such a method is also disclosed in the three-dimensional label obtained by the publication of the method of "stickable three-dimensional labeling" of the publication No. 200416634, which is the same way to generate a three-dimensional texture, so the problem is the same as the aforementioned patent.

Therefore, in order to improve the defects of the above patent, there is Patent No. I270352 A multilayer material having a three-dimensional texture, which discloses a multilayer substrate, the bottom layer of which is a PET substrate, which is successively stacked as an EVA adhesive layer, an aluminum layer, and a PET film positioned at the topmost layer. Wherein, the PET film has a translucent property, and is provided with a plurality of convex portions corresponding to a three-dimensional texture and a plurality of concave portions on the same by hot stamping, and the aluminum layer attached to the PET film is also The EVA adhesive layer is automatically filled in the protrusions and the recesses for bonding the aluminum layer and the PET substrate when the protrusions and the recesses are simultaneously convex and concave. And forming a embossed decorative effect such as a pattern, a letter or a hybrid thereof, and the PET film can be used as a protective layer against oxidation and abrasion.

However, in the manufacturing process, since the coloring and hot stamping need to be heated and baked, the PET film must use a thicker plate to avoid deformation or wrinkles during the baking process, which affects the quality of the finished product due to The thickness of the finished product is relatively thicker, and the three-dimensional texture of the finished surface is relatively inconspicuous. In view of this, the creator chose a thinner (6μm~8μm) light-transmissive film to replace the original PET film, and can use the thinner characteristics to make the three-dimensional texture more prominent. However, during processing Because of the thin thickness, it can not be processed by hot baking, especially in the process of coloring, in order to make the color material firmly adhere to the light-transmissive film, so the manufacturing method of the present invention is proposed. Solve the problem that the ultra-thin transparent film cannot be baked by heating.

One of the aims of the present invention is to provide an ultra-thin color film manufacturing method and a finished product thereof, and to attach an ultra-thin light-transmissive film to a base film by using a thick film of a thicker thickness, The bonding and supporting effect of the adhesive film and the base film enables the ultra-thin transparent film to resist the temperature during baking, and does not cause deformation or wrinkles at the edges, thereby improving the convenience of subsequent processing. The effect of interest.

In order to achieve the above object, the ultra-thin color film manufacturing method of the present invention comprises: providing a base film, a bonding glue, an ultra-thin transparent film and a color material, and the thickness of the base film is between 30 μm and 50 μm. The thickness of the ultra-thin transparent film is between 6 μm and 8 μm; the adhesive is applied on one side of the base film on average; and the adhesive is first baked to a semi-dry state using a first set temperature. The adhesive is fixed on the base film; the base film and the ultra-thin transparent film are rolled, and the adhesive is in a semi-dry state to bond the two together; using the color coating The cloth is colored on the other side of the ultra-thin transparent film; and the color material is baked to the all-dry state for a second time using a second set temperature, so that the color material is fixed on the ultra-thin transparent film. The finished product is stored in a roll shape.

In one embodiment, the ultra-thin transparent film and the base film are each selected from one of a PET film and a PVC film, and the thickness is slightly different. And the first set temperature is between 80 ° C and 90 ° C to bake the adhesive to a semi-dry, the second set temperature is between 120 ° C and 180 ° C, so that the color is adhered tightly On the ultra-thin transparent film.

And a finished product produced by using the above-mentioned manufacturing method, comprising: the base film; the adhesive glue is coated on one side of the base film; and the ultra-thin transparent film is adhered to one side of the adhesive film After bonding the base film and the ultra-thin transparent film through the bonding glue, the deformation of the ultra-thin transparent film during baking is avoided by the base film: and the color material is coated on the super The other side of the thin light-transmissive film. The ultra-thin transparent film is colored, wherein the ultra-thin transparent film and the base film are selected from one of a PET film and a PVC film, for example.
