Abstract: The present disclosure is drawn to imaging media. In one example, an imaging medium includes a substrate, a color layer on the substrate, and an opaque porous concealing layer over the color layer. The color layer includes a pattern of color regions, wherein individual color regions include multiple adjacently-applied colors. The opaque porous concealing layer has a coat weight from 2 gsm to 10 gsm. The opaque porous concealing layer includes transparent inorganic particles having a refractive index from 1.3 to 3, and void spaces between the transparent inorganic particles are occupied by air.

Abstract: The present disclosure is drawn to ink fixative solutions, which can consist essentially of a polyvalent metal salt, a holdout additive, and water. The polyvalent metal salt can be present in an amount from about 1 wt % to about 5 wt %, with respect to the entire weight of the ink fixative solution. The holdout additive can be present in an amount from about 2 wt % to about 20 wt %, with respect to the entire weight of the ink fixative solution. The holdout additive can be polyethylene glycol, glycerol, carboxy methyl cellulose, hydroxy ethyl cellulose, a fatty acid, a fatty acid ethoxylate, or combinations thereof.

Abstract: Disclosed is a coated print media having a coating layer formed on at least one surface of a media substrate. The coating layer includes a binder and co-milled particles of precipitated calcium carbonate and zeolite. The specific zeolite used is either Zeolite A or Zeolite X, or combination of both. The co-milled particles are produced by milling precipitated calcium carbonate in the presence of zeolite, whereby the co-milled particles take on the form of aggregates.

Abstract: An example of a treatment composition for a packaging liner includes a fixing agent, a wax, and a latex. The fixing agent is selected from the group consisting of water-soluble mono-valent metallic salts, water-soluble multi-valent metallic salts, and combinations thereof. A total dry solids content of the example treatment composition ranges from about 5 wt % to about 40 wt % of a total weight of the treatment composition.
