The present disclosure is drawn to primer compositions, which can include a binder including polyvinyl alcohol, starch nanoparticles, and a polyurethane dispersion. The primer competitions can also include a cationic salt and water.

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.

A transfer paper used for a transfer printing method using sublimation textile ink, comprising a base paper and one or more coating layer(s) provided on at least one side of the base paper, wherein an outermost coating layer positioned on the outermost side with respect to the base paper contains at least a pigment, a binder, a polyacrylic acid salt and an acetylene glycol derivative, has image deterioration resistance, good color development property and excellent adhesion property.

A recording method includes a step of applying a first ink to a recording medium; and a step of recording an image on the recording medium by applying a second ink so that the second ink at least partially overlaps a region to which the first ink has been applied. The first ink is an aqueous ink containing a silver particle. The second ink is an aqueous ink containing a coloring material. The recording medium has an ink receiving layer that contains a halide ion selected from the group consisting of a bromide ion and an iodide ion. The ink receiving layer has a halide ion content (mmol/m.sup.2) of 0.1 mmol/m.sup.2 or more to 0.8 mmol/m.sup.2 or less.

There is provided an ink jet recording medium capable of recording images excellent in color developability and light resistance. The ink jet recording medium has a base material and an ink receiving layer provided on the base material. The ink receiving layer contains a wet silica, a binder, an ultraviolet absorber represented by the following general formula (1) (wherein R.sub.1 represents a hydrogen atom or a halogen atom; R.sub.2 and R.sub.3 each independently represent a hydrogen atom, an alkyl group, an alkyl group containing an ester group, or an alkylphenyl group), and a surfactant; in the ink receiving layer, the content of the ultraviolet absorber with respect to 100 parts by mass of the wet silica is 10 parts by mass or more and 20 parts by mass or less; and the surfactant is a polyoxyalkylene alkyl ether. ##STR00001##
