Embodiment 1

[0021] Embodiment 1: An inkjet printing film, including a substrate 14 , a colored layer 13 and an ink-absorbing coating 115 . The substrate 14 is a colorless PET transparent substrate (purchased by Suzhou Zhanxingda Electronic Materials Co., Ltd.). The colored layer 13 is blue. The ink-absorbing coating 115 is divided into two layers, each layer has holes, and the holes gradually become larger from the direction away from the substrate to the direction close to the substrate. The hole in the layered structure 11 away from the substrate has a diameter of 20-50 nm, and the hole in the layered structure 12 close to the substrate has a size of 50-100 nm.

[0022] Preparation:

[0023] S1, preparation of the colored layer:

[0024] Add blue dye (purchased by Zhongshan Chaozhan Trading Co., Ltd.) to the water-based polyurethane dispersion, and the mass ratio of blue dye to water-based polyurethane dispersion is 1:20. Add distilled water and stir evenly to configure a coloring l...

Embodiment 2

[0032] Embodiment 2: An inkjet printing film, including a substrate, a colored layer and an ink-absorbing coating. The substrate is a colorless PET transparent substrate (purchased by Suzhou Zhanxingda Electronic Materials Co., Ltd.). The colored layer is white. The ink-absorbing coating is divided into four layers, and each layer has holes, and the holes gradually become larger from the direction away from the substrate to the direction close to the substrate. The pores become larger in order from far away from the substrate to close to the substrate, 20-30nm, 30-50nm, 50-80nm, 80-100nm.

[0033] Preparation:

[0034] S1, preparation of the colored layer:

[0035] Add white dye (nano-titanium dioxide, particle size 50-100nm) to the water-based polyurethane dispersion, the mass ratio of white dye to water-based polyurethane dispersion is 1:50. Add distilled water and stir evenly to configure a coloring layer solution with a solid content of 15%.

[0036] S2. Coating of th...

Embodiment 3

[0045] Embodiment 3: An inkjet printing film, including a substrate, a colored layer and an ink-absorbing coating. The substrate is a colorless PET transparent substrate (purchased by Suzhou Zhanxingda Electronic Materials Co., Ltd.). The colored layer is blue. The ink absorbing coating is divided into six layers, each layer has holes. The holes are 20-30nm, 20-30nm, 30-50nm, 50-80nm, 50-80nm, 80-100nm in order from away from the substrate to close to the substrate.

[0046] Preparation:

[0047] S1, preparation of the colored layer:

[0048] Add blue dye (purchased by Zhongshan Chaozhan Trading Co., Ltd.) to the water-based polyurethane dispersion, and the mass ratio of blue dye to water-based polyurethane dispersion is 1:30. Add distilled water and stir evenly to configure a coloring layer solution with a solid content of 12%.

[0049] S2. Coating of the colored layer:

[0050] The coloring layer solution was evenly coated on a colorless PET transparent substrate (purc...

Abstract

The invention relates to the field of inkjet printing films, and in particular relates to an inkjet printing film and a preparation method thereof. The inkjet printing film comprises a substrate, a coloring layer and an ink absorbing coating, wherein the substrate is made of a transparent material, the coloring layer is blue or white, and the ink absorbing coating is in a multiple-layer structure. As the coloring layer is arranged, the blue or white bottom color can be completed through a base material in a unified manner, and the cost can be effectively reduced. As the layer-structure ink absorbing coating is arranged, the ink absorbing amount of the coating is increased.

Description

Technical field: [0001] The invention relates to the field of ink-jet printing film, in particular to an ink-jet printing film and a preparation method thereof. Background technique [0002] With the development of technology, digitally printed inkjet printing film is a new type of image film that has developed rapidly in recent years. At present, the medical film is to choose a blue or white PET sheet as the base material, coated with an ink-absorbing coating, the apparent quality of the film is also very good, but the cost is too high. [0003] The ink absorption amount and ink absorption stability of the ink absorbing coating have a great influence on the printing effect, the ink absorption amount has a major impact on the color expressiveness of the film, and the ink absorption stability has a direct impact on the waterproof ability of the film. Usually, the thickness of the ink-absorbing coating is increased to increase the ink-absorbing capacity, and at the same time,...
