Being washed off by the blank parts aluminium lamination of uncoated protective layer ink, then deionized water cleans and remains to without aqueous alkali, at 45-55 DEG C
Dry, obtain double-deck holography shifting film；
Step (5), is coated with cold wave gold UV glue while printed on paper pattern, then complete with the bilayer described in step (4)
It is compound that breath transfer membrane carries out bonding, after glue curing, uses stripping machine to be peeled off by BOPP thin film, i.e. obtains double-deck holographic false proof
Transfer paper；
The preparation method of the cold wave gold UV glue described in step (3) and step (5) is first, to prepare in parts by weight such as
Lower raw material: urethane methacylate resins 20-30 part, benzoin dimethylether 1-3 part, 2-ethyl phenylacrylate 55-82
Part, NVP 25-33 part, ethylenediamine 5-8 part, coupling agent KH550 2-3 part, polymerization inhibitor 0.1-0.2 part, pregnancy
Base phosphoric triamide 0.5-2 part, arabic gum 0.1-0.2 part；Then the raw material of preparation is heated to 40-50 DEG C, in 100-200r/
The speed stirring 20-30min of min, i.e. obtains cold wave gold UV glue.
The preparation method of double-deck holographic false proof transfer paper the most according to claim 1, it is characterised in that described ground floor
Anti-counterfeiting mark in hologram layer is different from the anti-counterfeiting mark in second layer hologram layer.
The preparation method of double-deck holographic false proof transfer paper the most according to claim 1, it is characterised in that step (3) is described
The spread of cold wave gold UV glue be every square metre of moisture 8-10g.
The preparation method of double-deck holographic false proof transfer paper the most according to claim 1, it is characterised in that step (5) is described
The spread of cold wave gold UV glue be every square metre of moisture 9-11g.
The preparation method of double-deck holographic false proof transfer paper the most according to claim 1, it is characterised in that step (1) is described
The thickness of BOPP thin film be 18-25 μm.
6. the double-deck holographic false proof transfer that the preparation method of claim 1-6 any one bilayer holographic false proof transfer paper prepares
Paper.
