Hetero-polycyclic compounds, and coloring matters, pigments, dyes, color-changing material compositions, and color-changing films, made by using the compounds |
摘要 |
Provided are novel hetero-polycyclic compounds having a specific structure, color-changing material compositions comprising (A) a fluorescent coloring matter comprising at least one of the hetero-polycyclic compounds described above and (B) a binder material, color-changing films comprising the above hetero-polycyclic compounds, coloring matters comprising the above hetero-polycyclic compounds, and pigments or dyes comprising the hetero-polycyclic compounds described above, and provided are color-changing material compositions which are not deteriorated in a color-changing performance even after used for long time and which are prevented from being unusable due to deposition of coloring matters during storage and color-changing films produced by using the same, and novel hetero-polycyclic compounds, coloring matters and pigments or dyes which actualize them.
