摘要： A phthalide compound of general formula (I) and a near infrared absorber and a recording material each utilizing the phthalide compound are disclosed. ##STR1## wherein ring A represents a substituent group of the following formula ##STR2## where the other substituents are as defined in the disclosure. The near infrared absorber and the recorded image on the recording material absorb strongly the near infrared region with no appreciable absorption in the visible region of the spectrum. The near infrared absorber is colorless or pale in color and yet highly capable of absorbing near infrared radiation. The recorded image on the recording material can hardly be read with the eye but can be read with the OCR. Moreover, the effect on the developed shade of any concomitant color former in a recording material is minimal.
摘要翻译：本发明公开了通式（I）的酞化合物和近红外吸收剂以及各自使用苯酞化合物的记录材料。记录材料上的近红外吸收体和记录图像强烈地吸收近红外区域，在光谱的可见光区域没有明显的吸收。近红外吸收剂是无色或浅色的，但能够吸收近红外辐射。记录材料上的记录图像几乎不能用眼睛读取，但可以用OCR读取。此外，对记录材料中任何伴随的成色剂的显影性的影响最小。
