Abstract
An anti-static playing card is a plastic playing card having a front surface and a back surface, wherein each of the surfaces has a first anti-static paint layer in which a surfactant and a coloring agent are added for displaying a suit and a number on the front surface and displaying a pattern on the back surface, and each of the surfaces has a transparent second anti-static paint layer that has a surfactant added therein and is coated over the first anti-static paint layer, so that the anti-static playing card is prevented from accumulation of static electricity.
Claims
1. An anti-static playing card, which is a plastic playing card having a front surface and a back surface, wherein each of the surfaces has a first anti-static paint layer in which a surfactant and a coloring agent are added for displaying a suit and a number on the front surface and displaying a pattern on the back surface, and each of the surfaces has a transparent second anti-static paint layer that has a surfactant added therein and is coated over the first anti-static paint layer, so that the anti-static playing card is prevented from accumulation of static electricity.
2. The anti-static playing card of claim 1, wherein the surfactant added in the first in anti-static paint layer and the surfactant added in the second anti-static paint layer are both polyoxyethylene lauryl ether.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0011] The invention as well as a preferred mode of use, further objectives and advantages thereof will be best understood by reference to the following detailed description of illustrative embodiments when read in conjunction with the accompanying drawings.
[0012] Referring to FIG. 1 through FIG. 3, a plastic playing card 10 has a front surface 11 and a back surface 12. Each of the surfaces of the plastic playing card 10 has a first anti-static paint layer 20 in which a surfactant and a coloring agent are added for showing a suit 111 and a number 112 on the front surface 11 and showing a pattern 121 on the back surface 12. A second anti-static paint layer 21 is coated on the outer surface of the combination of the plastic playing card 10 and the first anti-static paint layer 20. It is transparent and also added with a surfactant. With the foregoing configuration, the plastic playing card 10 is prevented from accumulation of static electricity.
[0013] The composition, effects and details of the foregoing embodiment will be discussed below. As shown in FIG. 1 through FIG. 3, the disclosed plastic playing card 10 has its front surface 11 displaying the suit 111 and the number 112 distinctive in a deck of said playing cards 10. The suit 111 and the number 112 may be printed using screen printing, and the first anti-static is added with a coloring agent (such as one for black, red, yellow or other colors) and a surfactant. The surfactant acts as a paint additive for reducing surface tension of the paint so as to improve clarity of the printing. In addition, the surfactant may be a non-ionic surfactant made of polyoxyethylene lauryl ether. When it is attached to the surface of the plastic material, outward-facing hydrophilic groups absorb trace moisture in the ambient environment, so that the surface of the plastic material has high moisture affinity and becomes electrically conductive, thereby allowing static electricity to escape along the surface of the object and leak timely. Then a printing plate having the same suit 111 and number 112 is reserved on the halftone, so that when printing is made on the front surface 11 of the plastic playing card 10, the first anti-static paint layer 20 containing the coloring agent permeates through the halftone and gets deposited on the front surface 11, thereby making the suit 111 and the number 112 with sharp contours. The anti-static paint may be cured by exposing it to ultraviolet. Then the same screen printing process is repeated for the back surface 12 to make the pattern 121, thereby completing printing of the front and back surfaces 11, 12 of the plastic playing card 10 and forming the first anti-static paint layer 20. The second anti-static paint layer 21 is made using a second anti-static paint that is transparent. For ensuring anti-static effects of the plastic playing card 10, the second anti-static paint is sprayed, applied or rolling-painted all over the front and back surfaces 11, 12 of the plastic playing card 10. In this case, the suit 111, the number 112, the pattern 121 and any other area that is not covered by the first anti-static paint can be covered by the second anti-static paint. Thereby the second anti-static paint layer 21 is formed to provide overall anti-static effects and contribute to improved endurance of the first anti-static paint layer 20.
[0014] The present invention has been described with reference to the preferred embodiments and it is understood that the embodiments are not intended to limit the scope of the present invention. Moreover, as the contents disclosed herein should be readily understood and can be implemented by a person skilled in the art, all equivalent changes or modifications which do not depart from the concept of the present invention should be encompassed by the appended claims.
