Description

Plate with three-dimensional color glare effect

The present invention relates to a sheet material with three-dimensional color glare effect, in particular to an innovative structure of sheet material that does not need to use glue between the layers and is integrally formed in a high temperature environment without falling off or separating.

The traditional surface is formed with a pattern that can produce three-dimensional color and glare visual effect. It has a wide range of applications, such as game cards, placemats, cards, etc. Because its surface has a three-dimensional color and glare visual effect, it can be improved The economic value of the molded product. Among them, the surface is provided with a plate with a pattern that can produce three-dimensional color and glare visual effect, which is generally used on polyethylene terephthalate (PET, polyethylene terephthalate) for electroplating to form a reflective film, and then on The reflective film is glued to a bonding layer made of polyethylene terephthalate (PET), and the bonding layer is glued to a substrate made of polypropylene (PP), and then further After embossing, glazing, printing, etc., a sheet-like board that can produce three-dimensional color and glare visual effect patterns can be formed.

However, although the above-mentioned sheet-like sheet structure has the expected effect of a three-dimensional color glare visual effect pattern, it has the following shortcomings in actual implementation:

1. The reflective film of the substrate and the substrate cannot be directly combined and formed between the reflective film and the substrate after the electroplating operation, and a bonding layer must be provided between the reflective film and the substrate, so that the reflective film is bonded with adhesive The layer (PET) is connected and bonded, and then the bonding layer (PET) and the substrate are bonded with adhesive. Because the reflective film and the bonding layer (PET) and between the bonding layer (PET) and the substrate must be reattached The use of secondary adhesives for bonding and fixing operations leads to an increase in manufacturing costs.

2. Because the adhesive is not resistant to high temperatures, it is prone to degumming. Even after a period of time, the adhesive is aging, causing peeling between the reflective film and the bonding layer (PET) or between the bonding layer (PET) and the substrate, resulting in The molded product produced has defects, and its production yield is not good.

The reason is that, in view of this, the inventor of the present invention has many years of rich experience in design, development and actual production in the related industry, and has researched and improved the existing structure and defects, and provided a sheet with three-dimensional color glare effect in order to achieve better practicality.
