Problems solved by technology

[0018] Furthermore, there are examples of using polysulfides (disulfides and trisulfides, any one of which has a molecular weight of less than 1000), but the effect of improving the ozone resistance of these compounds is not sufficient (for example, refer to Patent Document 7
[0024] However, the polymer compound described in Patent Document 12 is an organic particle having a Tg of 70° C. or higher, so glossiness is insufficient.

Embodiment

[0318] The present invention will be specifically described below by way of examples, but the present invention is not limited to these examples. In addition, "parts" and "%" in the examples represent "parts by mass" and "% by mass" unless otherwise specified, and "average molecular weight" and "degree of polymerization" represent "weight average molecular weight" and "weight average molecular weight". Average degree of polymerization".

Synthetic example 1

[0321] 13.5 parts of polybutadiene (NISSO-PB G1000: manufactured by Nippon Soda Co., Ltd.), 15.6 parts of 2-mercaptoethanol, and 2.84 parts of aminoethanethiol hydrochloride were dissolved in 13.5 parts of ethyl acetate / isopropanol = 1 / 1wt mixture. It was heated to 70° C. under a nitrogen stream, 0.062 parts of 2,2-azobis(2,4-dimethylvaleronitrile) [trade name: V-65, manufactured by Wako Pure Chemical Industries, Ltd.] was added, and the Heating and stirring at ℃. After 2 hours, 0.062 parts of V-65 was added, followed by heating and stirring at 70° C. for 4 hours.

[0322] 128 parts of ion-exchanged water was uniformly added thereto and emulsified, and then the solvent was distilled off to obtain an emulsion of polymer 1 (exemplary compound: P-6, sulfur equivalent: 7.18 meq / g, I / O value: 1.17).

Synthetic example 2

[0324] Polymer 2 (exemplary compound: P-7, sulfur equivalent: 5.47meq / g , I / O value: 1.74) aqueous solution.

Abstract

PROBLEM TO BE SOLVED: To provide a recording medium which enables the formation of a high-resolution and high-density image, and which exerts the excellent effect of preventing fading from being caused by an ozone gas in the atmosphere, without causing bleeding with time, even if stored for a long period of time under the high-temperature and high-humidity environment after printing. SOLUTION: This recording medium with a recording layer provided on a substrate is characterized in that the recording layer contains a polymer which has a thioether bond, whose sulfur equivalent is 1.2 meq / g or more, and wherein an inorganic / organic ratio (I / O value) shown in the organic conceptual diagram is 0.5 or more.
