Description

Technical Field

[0001] This utility model relates to the field of contactless IC card manufacturing, and more specifically, to a contactless IC card that can achieve a pearlescent effect. Background Technology

[0002] With the development and progress of science and technology, more and more new materials are being applied to various industries. For example, in the production of bank cards, membership cards and other cards, special effects are usually added to the surface of the cards to enhance their visual appeal and aesthetics.

[0003] First, the pearlescent pattern is printed on the surface of the card, then an adhesive layer is applied, and then the card with the pearlescent pattern and adhesive is pressed together with the outermost material at high temperature.

[0004] In actual production, since card-type products are made of multiple layers under high temperature and pressure, printing a layer of pearlescent ink will affect the peel strength of that layer. In addition, the extra layer of ink causes uneven heat conduction within the card body, which can easily lead to card deformation or even excessive melting of parts of the card body, resulting in irregular "flow edges".

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a contactless IC card that can achieve a pearlescent effect, solving the problem that existing pearlescent contactless IC cards are easily peeled off due to the pearlescent layer.

[0007] This utility model discloses a contactless IC card with a pearlescent effect. The contactless IC card includes a substrate, a pearlescent layer, and an outermost layer. The pearlescent layer is disposed between the substrate and the outermost layer. The pearlescent layer is printed by mixing pearlescent powder and water-based adhesive.

[0008] In some embodiments, the innermost layer of the contactless IC card is provided with a pearlescent pattern.

[0009] In some embodiments, the pearlescent pattern is formed by the following steps: taking a water-based adhesive and placing it in a container; taking pearlescent powder and pouring it into oil; stirring the mixture thoroughly; printing the prepared water-based adhesive onto the inner side of the outermost layer of the contactless IC card; and finally pressing it at high temperature to form a contactless IC card.

[0010] In some embodiments, the pearlescent powder particles selected in the pearlescent layer have a particle size of 300-500 mesh. Pour the water-based binder and powder into the oil at a ratio of (200-400):1; and stir the mixture thoroughly with a stirrer.

[0011] The step of “printing the prepared water-based adhesive on the inner side of the outermost layer of the contactless IC card and finally pressing it into a contactless IC card at high temperature” is as follows: select a 150-350 mesh screen printing plate, print the prepared water-based adhesive on the inner side of the outermost layer of the contactless IC card, and then let it dry; after it is completely dry, proceed to the next process and finally press it into a contactless IC card at high temperature.

[0012] In some embodiments, 300-500 mesh pearlescent particles are preferred because they better showcase the subtle, shimmering effect of pearlescent sheen. When the pearlescent particles are large, they are too noticeable and easily obscure the pattern, failing to achieve the desired subtle pearlescent effect. Conversely, when the particles are too small, the pearlescent effect is too weak and difficult to observe, resulting in a poor overall effect. Furthermore, the pearlescent particle size chosen in this invention also considers the characteristics of screen printing, ensuring a good pearlescent effect even when used with commonly used screen printing stencils.

[0013] A preferred ratio of water-based adhesive to powder is (200-400):1 for a better pearlescent effect. Adding too much pearlescent powder will affect the gloss and darkness of the card surface, while adding too little will prevent the pearlescent effect from appearing.

[0014] Using a screen printing plate with a mesh size of 150-350 for screen printing of mixtures is preferred, as it is convenient to meet the needs of daily production and can also produce better printing results.

[0015] In some implementations, the outermost layer of the contactless IC card is a transparent protective layer.

[0016] In some embodiments, the pearlescent powder is cobalt silver powder.

[0017] In some embodiments, the pearlescent powder is a metal oxide-based pearlescent powder or a mica-based pearlescent powder.

[0018] In some embodiments, the pearlescent powder is preferably 350-450 mesh in size.

[0019] In some embodiments, the pearlescent powder is preferably 400 mesh in size.

[0020] In some embodiments, preferably, the water-based adhesive: powder ratio is (250-350): 1.

[0021] In some embodiments, preferably, the water-based adhesive: powder ratio is 300:1.

[0022] In some implementations, a 200-300 mesh screen printing plate is preferred.

[0023] In some implementations, a 250-mesh screen printing plate is preferred.

[0024] The technical solution of this utility model brings at least the following beneficial effects:

[0025] 1) The method provided by this utility model overcomes the problems of easy peeling of pearlescent patterns, thickening of contactless IC cards, and high cost in the existing thermal transfer process, and enables contactless IC cards to present different colors and textures.

[0026] 2) The method provided by this utility model is simple and convenient to operate, and overcomes the problem of easy peeling.

[0027] 3) The method provided by this utility model will not increase the risk of card deformation.

[0028] 4) The method provided by this utility model facilitates the adjustment of the density of pearlescent powder, ultimately achieving a better pearlescent shimmering effect.

[0029] 5) The process provided by this utility model reduces the number of screen printing operations from 2 to 1, improving production efficiency and greatly saving manpower and material costs.

[0030] 6) The method provided by this utility model is applicable to the production of various types of contactless IC cards, such as bank cards, credit cards, and ID cards.

[0031] Of course, any product implementing this application may not necessarily achieve all of the advantages described above at the same time. Attached Figure Description

[0048] Furthermore, the method provided in this embodiment can also select pearlescent powders of different colors and textures according to customer needs, thereby producing contactless IC cards of different styles.
