PHOTOSENSITIVE DRY FILM COMPOSITIONS |
| 摘要 |
A photosensitive dry film composition includes a hexaarylbiimidazole blend, a photosensitizer that absorbs in the 350 to 410 nm wavelength range and a hydrogen donor. The hexaarylbiimidazole blend includes a hexaarylbiimidazole having a molar extinction coefficient of at least 4,000 in the 350 to 410 nm wavelength range and a hexaarylbiimidazole having a molar extinction coefficient of less than 4,000 in the 350 to 410 nm wavelength range. |
