Detailed Description

For a better understanding of the technical content of the present invention, specific embodiments are described below in conjunction with the accompanying drawings.

The laser medium with the protective layer in the embodiment shown in fig. 1 includes a thin substrate 1, a laser layer 2, a nano protective layer 3, and a color coating layer 4. The laser layer 2 is also called a laser information layer and a holographic layer, and can provide holographic image content under the irradiation of light. The laser layer 2 comprises laser holographic pattern and/or text information.

The thin base material 1 is provided with a bearing surface for attaching an object to be borne, namely laser holographic patterns and/or character content information of a laser layer; the laser layer 2 is compositely fixed to the carrying surface of the thin substrate 1 and at least partially covers the carrying surface. That is, holographic content is typically partially, but not completely, covered on the bearing surface.

And the nanometer protective layer 3 is covered on the laser layer and the position on the bearing surface which is not covered by the laser layer by adopting nanometer paint.

Optionally, the nano protective layer 3 is formed by a titanium dioxide nano protective layer and an aluminum oxide nano protective layer, wherein the nano protective layer 3 is formed by a nano paint through a coating process, and optionally, the nano paint can be a commercially available titanium dioxide aqueous nano paint, such as titanium dioxide aqueous nano paints produced by shenzhen jeisebao scientific and technological development ltd and Jiangsu jin Heng novel packaging material ltd, and the formula of the nano paint is as proposed in patent documents CN102127325A and CN 103073932.

The upper color layer 4 is coated on the nano protective layer, especially coated on the side of the nano protective layer 3 far away from the laser layer 2, namely the upper surface.

The thin substrate can be made of different substrates under different application scenarios and requirements, for example, a plate or a film type substrate can be used.

In an alternative embodiment, the thickness of the sheet material is between 0.5mm and 1 mm. The thickness of the film type substrate is 0.1mm-0.8 mm.

The thin substrate 1 may be one of a PVC substrate, a PET substrate, an OPP substrate, a BOPP substrate, an aluminum foil substrate, and a base paper.

The thin substrate 1 may be a polyester substrate and may be formed into a sheet having a predetermined thickness.

In some embodiments, we take a sheet material with a thickness of 0.7 ± 0.01mm (for credit card applications) or 0.9 ± 0.01mm (for identity documents) as an example, and the process for making laser medium with a protective layer includes:

step 1: pretreating the thin base material 1, and cleaning and drying one side of a bearing surface;

step 2: the method comprises the following steps of gluing (coating process) an OPP transfer film (also called an OPP transfer film, which can be purchased from the market according to content requirements) with prepared holographic characters and/or holographic pattern information, compounding the OPP transfer film with a thin base material 1, and forming a laser layer 2 on a bearing surface of the thin base material 1 through compounding and curing processes;

and step 3: the nano protective layer 3 is coated on the laser layer 2, and a layer of isolation is formed on the outer side of the laser layer 2 to play a role in protection and brightening; wherein the thickness of the nano protective layer 3 is 15-50 nm;

and 4, step 4: and finally, coating a coloring layer 4 on the outer surface of the nano protective layer 3, wherein the coloring layer 4 can be prepared in advance according to the requirements of customers, so that the laser medium with the protective layer is finally formed.

When the thin base material 1 is made of a PVC material or a PET material, the thin base material is used as a hard outer package, such as wine beverage, artware and other easily damaged products with large volume and mass, or name cards, labels and the like are attached to the outer part of commodities, so that the thin base material has anti-counterfeiting and attractive effects.

In some embodiments, using an aluminum foil substrate or base paper as the thin substrate, the laser medium can be used as a packaging material for packaging, such as food (especially aluminum foil as the substrate), tobacco, gift, or other goods.

In some embodiments, polymer materials such as PVC substrate, PET substrate, OPP substrate, BOPP substrate, etc. are used as the thin substrate, and the laser medium can be used as a hard outer package or as a soft label sticker, which is beautiful and provides an anti-counterfeiting function for goods.

In other embodiments, where the substrate is a polyester material, it can be used to produce an identity document or other card-type document requiring security, the substrate 1 having a thickness of 0.9 mm. In order to increase the anti-scratch performance of the identity document, one side of the upper color layer 4, which is far away from the nano protective layer 3, is covered with a protective layer, and the protective layer comprises a PETG film layer or a pp film and is pressed on the upper color layer.
