Title:
MULTI-MEDIUM COMBINED PARTIALLY HOLOGRAPHIC SPRAYED ALUMINUM TRANSFER PAPER AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/082548
Kind Code:
A1
Abstract:
A multi-medium combined partially holographic sprayed aluminum transfer paper and a preparation method therefor, related to the technical field of sprayed aluminum transfer paper. The method comprises the following steps: step 1. partial compounding: using a positioning partial compounding method to manufacture partially aluminum-plated transfer paper; step 2. dry compounding: using a positioning dry compounding method to transfer a thin film plated with a zinc sulfide laser pattern to the sprayed aluminum paper prepared in step 1, to obtain a multi-laser transfer paper. The multi-medium combined partially holographic sprayed aluminum transfer paper can simultaneously display on a single sheet of paper two different effects, namely an aluminum-plated positioning pattern and a zinc-sulfide-plated positioning pattern, increasing the variety of color patterns and improving anti-counterfeiting performance; subsequent printing does not require large amounts of white ink for covering the aluminum plated layer, thereby improving production efficiency, saving materials, and reducing the amount of ink used; and in the preparation process, aluminum washing is not required, and the process steps are simple.
