Abstract: A pattern formation board structure is disclosed. The board structure comprises a main board having hollow stripes with a specific main pattern; a secondary board being an extension from the edge of the main board having hollow stripes with a secondary pattern corresponding to the main pattern of the main board at a different position such that the respective shape and size of the secondary pattern and the main pattern are similar; thereby the main board and the secondary board form into a pattern formation board, by spraying or coating the hollow stripes, a plurality of patterns of multiple colors can be obtained.

Abstract: A three-dimension ornamental article is disclosed. The member comprises a plasticizing layer coated onto a substrate, an electroplated layer covered the plasticizing layer and an adhesion layer, wherein the plasticizing layer is epoxy resins or plastics. The base paper is a patterned layer and the circumferential edge of the patterned layer has dotted scored lines, facilitating the peeling off of the ornamental article.

Abstract: The puffy sticker contains a base layer, and one or more pattern layers made of a puffy material coated sequentially on pre-determined areas of a top side of the base layer in a layer-by-layer manner, where these pattern layers jointly present a colorful graphic image. The graphic image is then bulged by thermally curing these pattern layers. A cutting line is provided surrounding the graphic image so that the sticker having the puffy or foamy image can be detached. The base layer is made of paper, cloth, or similar material which adhesives coated on a bottom side of the base layer.

Abstract: A sticker package includes a sticker assembly and a package case. The sticker assembly includes an elongate strip of flexible film and a continuously extended sticker attached to a surface of the flexible film. The sticker has a projection area on the surface of the flexible film that is smaller than the surface area of the surface of the flexible film. The package case includes upper and lower lids. The upper lid is bulged to form a receiving compartment. The lower lid is cut to form an opening. The sticker assembly is wound up as a roll received and retained in the receiving compartment with a leading end extending out of the case through the opening. To use, the sticker assembly is pulled off the package case through the opening and the sticker is then allowed to peel off the flexible film.

Abstract: A transfer-printing sticker includes a release paper, a transparent base paper, and first and second sticking members carrying different patterns with the patterns arranged between the base paper and the release paper. The first sticking member contains a first pattern that is arranged to contain hollow portions. The second sticking member contains a second pattern that is arranged in accordance with the hollow portions of the first pattern. To use the transfer-printing sticker, the release paper is removed and the base paper is stuck to an article or a piece of paper and with slightly pressurization, the patterns are transferred. The arrangements of the first and second patterns allow for formation of different transfer printing effects. The second pattern can be set in the hollow portions of the first pattern and thus both can be formed with the same piece of sticker paper.
