コーティングカプセル構造を用いた浸水ラベル
Document Type and Number:
Japanese Patent JP5844904
Kind Code:
B2
Abstract:
The present invention relates to a water-ingress label using a double coating capsule structure. The invention comprises: a water absorbent layer which is formed from any one of paper, synthetic paper, nonwoven fabric, synthetic non-woven fabric, Korean paper or an absorbent coating for absorbing water; an ink layer which is formed by being printed onto the back surface of the water absorbent layer as an ink having a double coating capsule structure comprising 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 a plurality of water-soluble dyes, pigments, metallic silica, metallic oxides and mica. The present invention has strong humidity resistance due to the ink barrier layer and water-repellent layers on both surfaces and a crosslinking agent and the extent of crosslinking and adjustment of the thickness and the physical properties of the resin in the ink having the double coating capsule structure; and, in contrast to existing colour changes, two different colour changes are made possible and thus the present invention provides the advantage that it is even possible to accurately check whether water ingress has taken place over a narrow area.
