Pyrophthalones as Blue Wavelength Absorbers in Thermoplastic Media

Arunkumar Natarajan; Andrew Burns; Michael T. Takemori; Sumeet Jain; Eugene Pauling Boden; Vinodkumar Vasudevan; Kiran Puthamane; Shantaram Narayan Naik; George Kuriakose

We have explored the utility of pyrophthalones as violet‐blue light filtering dyes in polymer matrices for wavelengths below 450u2003nm. Further, we have investigated the photodegradation of these molecules in thermoplastic media and the mechanisms behind their degradation. Finally, a range of additives have been explored to improve the photostability of these molecules to achieve the desired performance.


Joint International Symposium on Optical Memory and Optical Data Storage | 2011

Recent Progress on Micro-holographic Data

Advances in micro-holographic materials and systems are presented. New materials show improved index change (10x) and sensitivity (100x) at >3x lower intensity vs. previously reported. Experimental results supporting single-sided optical drive concept is presented.
