| PURPOSE:To provide a multi-color thermal recording material having excellent decoloring performance in low temperature coloring layer and excellent color separation performance, in a multi-color thermal recording material composed of at least one decoloring agent, two kinds or more dyes and one kind or more developer, by incorporating two kinds or more leuco dyes having excellent decoloring performance in the low temperature coloring layer. CONSTITUTION:Preferably, combination of leuco dye is composed of green, magenta yellow, cyan, magenta, etc., and combination of green and magenta is especially preferable. Any leuco dye being conventionally employed in this type of thermal material can be employed freely, for example leuco compound of triphenyl methane series, fluoran series, phenothiazine series, auramine series, spiropilane series, indolinophthalid series dye is employed. In order to obtain a two color thermally recording material, liquid containing dispersed or dissolved coloring dye, developer, decoloring agent, binder, etc., is applied onto a supporting material such as paper, synthetic paper, plastic film, etc., then it is dried, and said process is repeated. | ||||||

| PURPOSE:To enable a fixing in a color-forming state, by a method wherein a recording layer containing a fluorane leuco dye shown by a specific general formula and an ascorbic acid 6-0-acyl derivative is formed on a substrate. CONSTITUTION:A coating liquid is prepared by dissolving or dispersing a mixed material of a fluorane leuco dye shown by formula I (R1, R2 represent respectively hydrogen, a 3-18 C alkyl, aralkyl, aryl, substd. aryl, and cycloalkyl, and R3 represents alkyl, halogen, alkyl aralkyl, and aryl-substd. amino), an ascorbic acid-6-0-acyl derivative, and a binder in a solvent such as an acetone. This coating liquid is applied on a substrate, such as a paper, plastic, and synthetic paper, and dried; in this manner, a reversible recording material is produced. | ||||||

| This invention relates to a new pigment in feed for salmonids, a new feed comprising this pigment and use of this pigment. The pigment comprises a diester of predominantly (3R,3'R)-astaxanthin, cantaxanthin or other carotenoids that can be used for pigmentation of salmonids prepared with an omega-3 fatty acid and/or a shortchain corboxylic acid. By this invention a pigment for feed to salmonids that is more or as stable as, and biologically more effective than free astaxanthin and previously known diesters of astaxanthin and commercially available astaxanthin and cantaxanthin products, is provided. The said diesters are also useful for enhancing the growth of farmed fish, as a growth-enhancing agent in feed for farmed fish, as an appetizer in feed for fish as well as for increasing the utilization of the feed for farmed fish, and foroptimising health and well-being of farmed fish. | ||||||
