    摘要: A near infrared ray absorbing compound having an improved solubility and light resistance can be obtained by amidating and/or imidating the amino groups on substituents of a phthalocyanine. According to its preparation process, the desired near infrared ray absorbing compound can be easily prepared by reacting the phthalocyanine having an elimination group such as a halogen atom with a 2-amino-thiophenol derivative, and then amidating and/or imidating a part or all of the remaining primary or secondary amino groups. Moreover, substituents on the benzene rings of the phthalocyanine can be coordinated with metals, whereby an absorption wavelength can be broadened and the near infrared rays in a long wave range can be absorbed. The near infrared ray absorbing compound of the present invention is useful as a heat ray absorbing material.
