Description

Adhesive laser advertising material

technical field

The utility model relates to an adhesive-backed laser advertising material, which belongs to the technical field of laser advertising materials.

Background technique

Holographic technology was first discovered by American scientist MJ Buerger when he used X-rays to take photos of the atomic structure of crystals. In the late 1970s, the surface structure of people's holograms was transferred to materials such as high-density photosensitive films. In 1980, American scientists used embossed holographic technology to transfer the holographic surface structure to polyester film, thus successfully printing out the world's first embossed holographic image. This kind of laser holographic image was later adopted by laser holographic technology. Widely used in anti-counterfeiting, packaging and decoration and other fields.

Traditional laser advertising materials usually add a laser layer and an inkjet layer on the base material in sequence. For example, the patent application number: 200620031150. The material, the information layer of which is PVC material, is used as the receiving material of the solvent-based ink. Usually, adding a coating on top of the laser layer will weaken the laser effect. The more layers, the weaker the laser effect.

Contents of the invention

The purpose of the utility model is to provide a laser advertisement material with higher laser brightness and reflectivity, so as to improve the visual effect of the laser advertisement.

In order to achieve the above object, the technical solution of the present utility model is to provide a kind of self-adhesive laser advertising material, including a base material and a primer layer, a laser layer, a metal coating layer and an inkjet layer arranged sequentially on the base material from bottom to top. It is characterized in that a pressure-sensitive adhesive layer is arranged under the substrate, and a release paper layer is arranged under the pressure-sensitive adhesive layer.

The utility model has the advantages of: 1. The metal coating can improve the reflection efficiency and highlight the laser effect; 2. The number of coatings on the laser metal layer is reduced, the light reflection efficiency is improved, and the laser effect is further enhanced; 3. Advertisements can be pasted on the glass , cars, billboards, on the wall, easy to use. Advertisements made with this laser advertising material have a very high laser effect, thereby effectively improving the publicity effect of the advertisement.

Description of drawings

Figure 1 is a schematic diagram of the structure of the back-adhesive laser advertising material.

Detailed ways

The utility model will be specifically described below in conjunction with the embodiments.

Example 1

As shown in Figure 1, it is a schematic diagram of the structure of the adhesive laser advertising material. The adhesive laser advertising material is composed of a release paper layer 7, a pressure-sensitive adhesive layer 6, a base material 1, and a primer layer arranged in sequence from bottom to top. 2. Laser layer 3 , metal coating layer 4 and spray painting layer 5 .

The release paper 7 protects the pressure-sensitive adhesive layer 6 from contamination, and can also prevent unnecessary bonding of the pressure-sensitive adhesive during production, storage and application. The release paper 7 is selected from silicone oil paper and coated paper.

The pressure-sensitive adhesive layer 6 is selected from polyacrylate, SIS and SBS, silicone, and polyurethane pressure-sensitive adhesives.

The substrate 1 is selected from materials such as paper, leather, polymer film, cloth, non-woven fabric, fiber, and their composites.

The purpose of the primer layer 1 is to improve the flatness of the base material. It is usually a polymer resin material, which can be natural or synthetic, such as: cellulose, starch, PE, PP, PET, PVC, PS, PVA, polyvinyl acetate, etc., and their copolymers and blends.

The laser layer 3 is a laser transfer coating, which can be a solvent-based coating or a UV light-curing coating.

The metal coating 4 can improve the reflection efficiency and highlight the laser effect, and is selected from gold, silver, copper, aluminum, and has a thickness of 2-100nm.

The inkjet layer 5 can accept inkjet ink, and the ink is divided into solvent ink and water-based ink. For different inks, different printing materials need to be selected. For solvent-based inks, the material of the inkjet layer 5 is selected from PVC, acrylic, PS, cellulose and other materials; for water-based inks, the material of the inkjet layer 5 is selected from hydrophilic polymer resins, and hydrophilic polymers refer to materials containing hydroxyl, amino, Carboxyl groups, urea groups and other polymers that easily form hydrogen bonds with water molecules, such as: animal gelatin, polyvinyl alcohol, polyurethane, polymethacrylic acid, etc.; either a single polymer, or a copolymer or a blend .

In this embodiment, the substrate 1 is made of PP paper, the primer layer 2 is made of water-based varnish, the laser layer 3 is made of laser transfer coating, the metal coating layer 4 is made of aluminum layer, the inkjet layer 5 is made of animal gelatin, and the release paper layer 7 is made of silicone oil. pattern paper.

Its production method is as follows: coat primer layer 2 on PP paper (substrate 1), after drying, coat a layer of laser transfer coating to form laser layer 3, laser mold pressing, vacuum aluminum plating to form metal coating 4, aluminum layer The thickness is 20nm, and one deck of high-transparency animal gelatin is coated on the aluminum layer to form the spray-painting layer 5 . Apply pressure-sensitive adhesive under the PP paper to form a pressure-sensitive adhesive layer 6, and compound silicone oil release paper to form a release paper layer 7.

This material can be used to make inkjet photo advertisements with water-based dye ink and water-based pigment ink, and can be pasted on publicity boards, window glass, car bodies and other carriers.

Example 2

Similar to Embodiment 1, the difference is that the inkjet layer 5 is made of PVC.

Its production method is as follows: coat primer layer 2 on PP paper (substrate 1), after drying, coat a layer of laser transfer coating to form laser layer 3, laser mold pressing, vacuum aluminum plating to form metal coating 4, aluminum layer The thickness is 20nm, and a layer of PVC is compounded on the aluminum layer to form the inkjet layer 5 . Apply pressure-sensitive adhesive under the PP paper to form a pressure-sensitive adhesive layer 6, and compound silicone oil release paper to form a release paper layer 7.

This material can be used for inkjet photo advertisement production of solvent and weak solvent dye ink and solvent and weak solvent pigment ink, and can be pasted on publicity boards, window glass, car bodies and other carriers.
