Reversible thermal recording material providing high contrast image

Reversible thermal recording material providing high contrast image. Nishimura, Masaki; Yamane, Norio (Shinoji Seishi Kk, Japan). Jpn. Kokai Tokkyo Koho JP 08300816 A2 19 Nov 1996 Heisei, 15 pp. 7579-36-4 and 599-66-6 are also occured in this study. (Japanese). (Japan). CODEN: JKXXAF. CLASS: ICM: B41M005-26. ICS: B41M005-30. APPLICATION: JP 1995-109611 8 May 1995. DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) The material comprises a sheet support coated with a heat-sensitive layer contg. a dye precursor, a color-developer, which reversibly colors and decolors the precursor, contg. 31 arom. compd. having 31 sulfonyl(thio)urea group SO2NH(:X)NH (X = O or S) and 31 C311 straight alkyl group in its mol., and 31 arom. compd. selected from I, II, III, and IV (R1-7 = H, alkyl) as a decoloration promoter. The material provides high contrast images with good storage stability and the images can be erased in a short time. Thus, a polyester film was coated with a reversible heat-sensitive layer contg. 3-diethylamino-6-methyl-7-anilinofluoran, p-MeC6H4SO2NHCONHC6H4NHCOC17H35-p, and (p-MeC6H4CH2OCO)2 and with an overcoat layer to give a reversible thermal recording sheet. .

Thermal recording materials using benzyl oxalate and phenylsulfonate derivative as sensitizers

Thermal recording materials using benzyl oxalate and phenylsulfonate derivative as sensitizers. Okada, Akinori (Mitsubishi Paper Mills, Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 03215087 A2 20 Sep 1991 Heisei, 6 pp. (Japan). CODEN: JKXXAF. CLASS: ICM: B41M005-26. APPLICATION: JP 90-10273 19 Jan 1990. DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) The title materials contain a dye precursor, a color developer, dibenzyl oxalate (I), and II. The materials provide high d. images with low fog and good storage stability and prevent adhesion of stain to thermal head. Thus, a paper support was coated with a compn. contg. 7579-36-4 and 67811-06-7 are just another two chemicals used in this study. 3-dibutylamino-6-methyl-7-anilinofluoran, bis(3-allyl-4-hydroxyphenyl) sulfone, I and II to give a thermal recording paper. .
