<p><P>PROBLEM TO BE SOLVED: To provide an analyzing method of a solvent soluble coloring matter constituted so that a very small amount of a sample, which is composed of at least two kinds of solvent soluble coloring matters or coloring matter containing a resin or an additive, is precisely separated and extracted and qualitatively or quantitatively analyzed from the absorption spectra of the lights of an ultraviolet visible region and a small range of a near infrared part in a solution state. <P>SOLUTION: The sample containing at least one kind of the solvent soluble coloring matter is separated by high speed liquid chromatography and the absorption spectra of the lights of the ultraviolet visible region and a small range of the near infrared part are measured to qualitatively or quantitatively analyze the solvent soluble coloring matter. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
