Embodiment Construction
[0014] The present invention will now be further described with reference to the drawings and specific embodiments.
[0015] reference figure 1 This embodiment provides a color transparent watermark paper, the watermark part 1 of the watermark paper has a luminescent material 2 in the watermark part 1, and the middle of the area covered by the luminescent material 2 is provided with a water-insoluble fibrous material 3. The fibrous material 3 is provided with a plurality of holes 31 penetrating the upper and lower surfaces. The upper and lower surfaces of the luminescent material 2 are respectively covered with a layer of temperature-changeable powder 4, and the periphery of the temperature-changeable powder 4 is the smallest distance from the periphery of the luminous material 2 The distance is 5mm, and the maximum distance is 10mm. The luminescent material used here is zinc sulfide luminescent material, and the water-insoluble fiber is natural plant fiber.

Abstract
The invention relates to a piece of multiple anti-counterfeiting color transparent water marked paper with a good multi-anti-counterfeiting effect. The interior of the water marked part of the piece of water marked paper is filled with a luminescent material, the middle part of an area covered by the luminescent material is provided with a non water soluble fibrous material, a plurality of holes penetrating through upper and lower surfaces are formed in the non water soluble fibrous material, the upper surface and the lower surface of the luminescent material are respectively covered with a layer of temperature changing powder, the minimum distance between the periphery of the temperature changing powder and the periphery of the luminescent material is 5 mm, and the maximum distance is 10 mm. The invention further discloses a manufacturing method of the color transparent water marked paper and the manufacturing method of the color transparent water marked paper comprises four steps.
Description
Technical field [0001] The invention relates to a color transparent watermark paper and a manufacturing method thereof. Background technique [0002] At present, watermarked paper is made of special chemical resin and special printing methods, so that the resin penetrates the paper, changes the light transmittance of the paper, and produces predetermined watermark patterns with different light and shade when visually inspecting the light transmission. This technology basically does not destroy the original texture and characteristics of the paper, and it will not have any impact on writing and printing after printing. However, the anti-counterfeiting technology of these watermark papers is often single, and it is difficult to mix various anti-counterfeiting technologies, which cannot effectively increase the difficulty of anti-counterfeiting. Summary of the invention [0003] Therefore, in view of the above-mentioned problems, the present invention proposes a color transparent wa...
