Alkylphthalocyanine near-infrared absorbers and recording/display materials using the same. |
| 摘要 |
<p>Near-infrared absorbers which contain phthalocyanine derivatives in which the four benzene rings contained in the molecule independently have 1 to 4 substituents are light and thermal resistant and possess high molar extinction coefficients. Such near-infrared absorbers are useful in optical recording media, near-infrared absorption filters, and liquid crystal display devices.</p> |
