Adhesive layer

The adhesive layer, which is one component of the three-dimensional fabric according to the present invention, is a layer for enhancing adhesion between a fabric or the like as an object to be printed and a foamed layer or a planarizing layer. Since the adhesive layer includes polyurethane and a fluorescent material, it is possible to confirm whether the adhesive composition is uniformly applied during the process of fabricating the three-dimensional fabric, whether the adhesive composition is uniformly applied, and whether it is applied to the correct position in the form of a desired pattern, And the final product can be labeled to prevent counterfeiting and can be easily distinguished from counterfeit goods. The adhesive layer can be preferably formed by the above-mentioned adhesive composition.

Also, the foam layer may be formed by repeating the application of the composition for a foam layer several times according to a required level of dimensional sensibility. As the foaming agent, it is preferable to use a thermally decomposable foaming agent. Examples of the thermally decomposable foaming agent include azo compounds such as diazobutane copolymer, azo organic amido (ADCA) and azobis formamide, oxybenzene sulfonyl hydrazide (OBSH) And ydrazide such as palladium toluene sulfonyl hydrazide can be used. The content of the thermally decomposable foaming agent in the composition for the foam layer may be appropriately set in accordance with the type of the foaming agent, the expansion ratio (the ratio of the thickness of the foam layer to the thickness of the base layer containing the foaming agent) and the like. Generally, the expansion ratio is preferably 1.5 times or more, more preferably about 3 to 8 times. The composition for the foam layer may further include a foaming assistant agent for promoting the decomposition of the foaming agent to further improve the foaming effect.

The content of the foaming assistant in the foam layer composition is preferably 0.3 to 10 parts by weight, more preferably 1 to 5 parts by weight, per 100 parts by weight of the foam layer composition. In addition, an aqueous diluent is preferably used as the foam layer diluent. For example, distilled water, ethanol, methanol and the like can be used.
