Patent number: 7892702Abstract: Photosensitizing dyes are often used in conjunction with a photoacid generator in holographic recording media. Conventional photosensitizing dyes typically are limited by having an appreciable absorption of light when used in a sufficient concentration, such that the intensity of light decreases significantly with penetration into a recording medium. The present invention discloses a number of new 5-alkynyl substituted napthacene photosensitizing dyes that have low extinction coefficients coupled with good sensitizing properties, such that the problems associated with the photosensitizing dyes absorbing light are significantly reduced.Type: GrantFiled: February 21, 2008Date of Patent: February 22, 2011Assignee: ForceTEC Co., Ltd.Inventors: David A. Waldman, Eric S. Kolb, Kirk D. Hutchinson, Richard A. Minns
