The present invention includes a label, a label sheet and a method for manufacturing the label. The label includes a paper facestock having first and second surfaces and a layer of pressure sensitive adhesive proximal to the second surface. The label can be adhered to a substrate having pre-applied indicia to cover the indicia and the label is opaque enough to prevent the viewing of the covered indicia while matching the color of the substrate.

An object of the present invention is to provide base paper for vapor deposition paper that can provide vapor deposition paper with excellent barrier properties. The base paper for vapor deposition paper according to the present invention includes: a paper substrate; and a clay coat layer and a resin layer in this order on at least one surface of the paper substrate. A surface of the resin laver has a wetting tension of 50 mN/n or more as measured in conformity with JIS K 6768:1999 and a print-surf surface roughness of 2.5 ?m or less as measured in conformity with JIS P 8151:2004.

[Problems] Provided is a discoloring body which is discolored by application of water and has high glossiness and is excellent in applicability to various fields such as a toy field, a decoration field, and a design field. [Solution] A discoloring body including a supporting body, a porous layer in which a low refractive index pigment is fixed in a dispersed state by way of a binder resin, and a glossy resin layer, in which an occupancy area ratio of the glossy resin layer is 1% to 95% with respect to a 1 cm square at any position in the porous layer.

Disclosed herein are, for instance, coated substrates comprising cellulose-based substrates with surface-treated aqueous-based polymer coatings. In some embodiments, the aqueous-based polymer coatings are surface-treated using corona treatment. Methods of making and using the same are also disclosed.

A cellulosic structure includes a paperboard substrate having a first surface and a second surface.
