Manufacturing method of holographic anti-fake substrate and plastic substrate with imaging layer

Abstract

The invention relates to a manufacturing method of a holographic anti-fake substrate and a plastic substrate with an imaging layer. Imaging layer paint is coated on a common high molecular engineeringplastic plate with a thickness of not more than 3 mm through a coating machine to prepare the plastic substrate with the imaging layer with a thickness of 8 microns for a later makeup procedure. Themethod comprises the following steps: acrylic resins, normal propyl acetate, butanone, butyl ester, a leveling agent and a defoaming agent are mixed according to a set ratio for dilution as the imaging layer paint; and the imaging layer paint is coated on the plastic plate surface by using a lithography machine or a casting coating machine or a transfer film coating machine, and is dried and curedto form the plastic substrate with the imaging layer. The defect of unstable product quality in later procedures caused by pits in the surface of the plastic substrate prepared by such special processes as extrusion molding is overcome; the production cost in all holographic alumite process is reduced; the lightness of the plastic substrate is facilitated; the tailoring of small-size plastic substrate is facilitated; and excellent application and popularization values are achieved.

Description

technical field [0001] The invention relates to a manufacturing method of a holographic anti-counterfeiting base material and a plastic base material with an imaging layer, belonging to the technical field of holographic anodized aluminum. Background technique [0002] Holographic anti-counterfeiting has been widely used at present, from mass consumer goods such as tobacco and alcohol, food and beverage, daily chemical products, pharmaceutical packaging, to high-end cards, tickets and currency, etc., you can see this kind of anti-counterfeiting with holographic patterns membrane traces. The key to making anti-counterfeiting film lies in the holographic anodized aluminum process. The existing holographic anodized aluminum production process includes: photolithographic plate making, electroforming plate, imposition, film making, molding, aluminum plating, gluing, cutting and other processes. Specifically, it includes: the designer uses drawing software to draw the pattern req...

AI Technical Summary

Problems solved by technology

[0003] Existing plastic substrates are made by special processes such as extrusion molding. There will be more or less air on the contact surface between the mold and the plastic material that cannot be completely discharged, resulting in some pits on the surface of the finished plastic substrate. The holographic pattern only transfers a thin layer of imaging carrier through the plastic substrate. When pits appear on the plastic substrate, it will seriously affect the imaging quality; The base material is a disposable plastic plate with dimensions of about 800×800×4mm. The purchase price is high, and it is relatively thick, which is not conducive to dumping and transportation, and it is not convenient to manually cut small-sized plastic base materials.
