The present invention relates to a decorative material having excellent printability, and the decorative material according to the present invention has an ink-receiving layer having a radially fine sloping structure having a dendritic shape, whereby the absorbing and/or fixing property, i.e., printability, of the ink printed on the ink-receiving layer is improved, and clarity is excellent, so that aesthetic effects are excellent. In addition, since the ink-receiving layer is manufactured through UV curing, it can be directly coated on a substrate layer, and can include various kinds of substrate layers; and since it is manufactured using a solvent-free type resin composition without using an organic solvent, and has an excellent absorbing and/or fixing property with respect to a water soluble ink, it has environmental friendly advantages.

A smart sticker for determining the current state of raw meat for safe human consumption is provided. The smart sticker indicates the quality or decomposition of the meat by changing color. The smart sticker employs a cupric nitrate solution mixed with a polymeric silicon substrate that forms a complex with the valence electrons on the nitrogen atom of an amino acid residue. After this interaction occurs, the smart sticker changes color from, for example, light blue to purple.
