  • Process for producing aspartame derivatives, process for purifying aspartame derivatives, production intermediates, and process for producing production intermediates
    Publication number: 20020127320
    Abstract: N-[N-[3-(2-hydroxy-substituted phenyl)propyl]-L-&agr;-aspartyl]-L-phenylalanine 1-methyl ester derivatives, which are useful as sweeteners, may be conveniently produced by subjecting a 2-hydroxychroman derivative having various substituents on the benzene ring and aspartame to a reductive alkylation reaction. These compounds may be purified by subjecting such a derivative containing one or more impurities to a crystallization step to crystallize the same.

  • Printing method, image forming process, ink, ink set, recording unit, image forming apparatus and print
    Patent number: 6299675
    Abstract: Disclosed herein is a printing method comprising a step of applying a liquid composition containing a cationic substance and an ink containing an anionic substance respectively on a recording medium so that the liquid composition and the ink are in contact with each other on the recording medium, wherein the ink contains a coloring material at a concentration of not higher than 1% and has a pH of 10.5 or higher. The printing method permits the provision of an image having excellent water fastness, image quality and resistance to bleeding on plain paper and can prevent the occurrence of whitish haze at a highlight part.

  • Image forming method, ink-jet recording method and instruments used in such methods
    Patent number: 6238045
    Abstract: An image forming method to apply an ink to a printing medium includes applying a liquid composition having a polarity different from a polarity of the ink to an image forming region formed by the ink and the vicinity of the image forming region on the printing medium prior to the application of the ink, wherein a surface tension of the liquid composition is higher than that of the ink.
