A water-ingress label using a double coating capsule structure includes a water absorbent layer which is formed from any one of paper, synthetic paper, non-woven fabric, synthetic non-woven fabric, Korean paper or an absorbent coating for absorbing water; an ink layer which is formed on the back surface of the water absorbent layer as an ink having a double coating capsule structure including a colourant selected from any one or a plurality of water-soluble dyes, pigments, metallic silica, metallic oxides and mica together with a hydrophilic/water-absorbing halogen-free resin; and an ink barrier layer having a damp-proofing and water-proofing function, which is formed on the back surface of the ink layer and prevents leaking, into the back surface of the ink layer, of the colourant selected from any one or more of water-soluble dyes, pigments, metallic silica, metallic oxides and mica. |

1. A water-ingress label using a double coating capsule structure, wherein the water-ingress label comprises:
a first release layer for protecting an adhesive layer; a first adhesive layer formed on a back surface of the first release layer for attachment to various products; a first durable coating layer formed on a back surface of the first adhesive layer for protection from the outside environment; a first water-proof layer formed on a back surface of the first durable coating layer in order to prevent absorption of water from the outside; a water-absorbent layer formed on a back surface of the first water-proof layer from any one of paper, synthetic paper, nonwoven fabric, synthetic nonwoven fabric, Korean paper and an absorbent coating in order to absorb the water from the outside; an ink layer formed by printing, on a back surface of the water-absorbent layer, an ink with a double coating capsule structure comprising a colorant consisting of any one or plural ones of water-soluble dyes, pigments, metal, silica, metallic oxides and mica, and a hydrophilic water-absorbent halogen-free resin; an ink barrier layer having a damp-proofing and water-proofing function, which is formed on a back surface of the ink layer and prevents leaking, through the back surface of the ink layer, of the colorant of any one or plural ones of the water-soluble dyes, pigments, metal, silica, metallic oxides and mica; a second water-proof layer formed on a back surface of the ink barrier layer in order to reinforce the ink barrier layer; a second durable coating layer formed on a back surface of the second water-proof layer for protection from the outside environment; a second adhesive layer formed a back surface of the second durable coating layer for attachment to various products; and a second release layer formed on a back surface of the second adhesive layer. |
