BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a pattern card, and more particularly a pattern card on which a pattern or picture with a three-dimensional effect can appear by easily removing printing ink on a base material.
2. Description of Related Art
A pattern or picture will appear on a pattern when a user removes partial material on the pattern card according to a predetermined design.
With reference to FIG. 7, a first conventional pattern card is composed of an aluminum or copper plate (60), and dark paint (61) coated on the aluminum or copper plate (60). When a user removes the dark paint (61) by a drawknife according to the predetermined design, a pattern or picture appears.
However, because there is a high level of adhesion between the dark paint (61) and the aluminum or copper plate (60), and the dark paint (61) has a high level of cohesion in itself, it is very difficult for the user to remove the dark paint (61). Furthermore, the pattern or picture only appears with a color of silver or copper after the aluminum or copper is removed, so the pattern card's decorative effect is monotonous and uninteresting.
As illustrated in FIG. 8, a second conventional pattern card is composed of a paper sheet (70), an aluminum or copper film (71), and dark printing ink (72) coated on the aluminum or copper film (71). Because there is a high level of adhesion between the dark printing ink (72) and the aluminum or copper film (71), and the dark painting ink (72) has a high level of cohesion in itself, this pattern card has the same problems as mentioned above.
With reference to FIG. 9, a third conventional pattern card is composed of a paper sheet (80), an aluminum or copper film (81), dark printing ink (82), and picture printing ink (83) applied on the dark printing ink (82). Because there are high levels of adhesion among the dark printing ink (82), the picture printing ink (83) and the aluminum or copper film (81), and the dark printing ink (82) and picture printing ink (83) have a high level of cohesion in themselves, this pattern card has the same problems as mentioned above.
Therefore, the invention provides an improved pattern card to mitigate or obviate the aforementioned problems.
SUMMARY OF THE INVENTION
The main objective of the present invention is to provide a pattern card on which a pattern or picture with a three-dimensional effect can appear by easily removing printing ink on a base material.
Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference to FIGS. 1–2, a pattern card in accordance with the present invention has a paper sheet (10). A color texture layer (20) with regular or irregular patterns is printed on the paper sheet (10). The paper sheet (10) and the color texture layer (20) constitute a base material (not numbered). A wax layer (21) is formed on the color texture layer (20). A protection printing ink (22) is coated on the wax layer (21), and a picture printing ink (23) is partially coated on the protection printing ink (22) according to the designed picture's profile and contour. Alternatively, the picture printing ink (23) can be randomly coated on the protection printing ink (22) for a user to freely design the picture. Because the wax layer (21) is between the protection printing ink (22) and picture printing ink (23) to reduce the adhesion of the printing ink (22, 23), it is very easy for the user to remove the printing ink (22, 23).
The protection printing ink (22) and picture printing ink (23) can be mixed with wax in the proportion of 10% for reducing the cohesion of the printing ink (22, 23), so the protection printing ink (22) and picture printing ink (23) can be removed more easily.
In use, the user removes the picture printing ink (23) by moving a drawknife along the picture's profile and contour, and removes the protection printing ink (22) as well, so the designed picture appears on the color texture layer (20) with a three-dimensional effect The picture can be drawn as an animal such as a hippo or dolphin etc., as shown in FIG. 1.
The base material in accordance with the present invention has various configurations. With reference to FIG. 3, the base material is composed of the paper sheet (10) and the color texture layer (20). In another embodiment, as shown in FIG. 4, the base material is composed of the paper sheet (10) and a metal film (24) such as aluminum or copper film. The wax layer (21), protection printing ink (22), and picture printing ink (23) can be in turn provided on the metal film (24). The protection printing ink (22) and picture printing ink (23) also can be mixed with wax in the proportion of 10%. When the protection printing ink (22) and picture printing ink (23) are removed, the picture with metallic luster appears on the metal film (24). Alternatively, the picture printing ink (23) can be eliminated, and the user can freely draw on the protection printing ink (22).
With reference to FIGS. 5–6, in a further embodiment, the base material is composed of the paper sheet (10), a vacuum plating layer (30), and a plastic film (40). The wax layer (21), protection printing ink (22), and picture printing ink (23) are in turn provided on the plastic film (40). The protection printing ink (22) and picture printing ink (23) also can be mixed with wax in the proportion of 10%. When the protection printing ink (22) and picture printing ink (23) are removed, the picture appears on the plastic film (24). Alternatively, the picture printing ink (23) can be eliminated, and the user can freely draw on the protection printing ink (22).
The plastic film (40) can be a silver, gold, colorized or laser film formed on the vacuum plating layer (30).
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
