<P>PROBLEM TO BE SOLVED: To provide a method for evaluating aptitude of a pigment composition for obtaining an optical recording medium exhibiting a sufficiently excellent recoding characteristic, especially, at the time of high-speed recording, and an optical recording material used for such an optical recording medium. <P>SOLUTION: This method for evaluating aptitude of a pigment composition for optical recording medium comprises a 1st process for setting temperature of a sample containing a pigment composition or atmospheric temperature of a sample to two or more different predetermined temperatures, and measuring absorbance of predetermined wavelength light at each predetermined temperature concerning the sample, and a 2nd process for evaluating the aptitude at the time of containing the pigment composition in a recording layer of the optical recording medium based on one or more conditions to be set from a correlation between the predetermined temperatures and the absorbance. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
