Patent number: 5925507Abstract: A highly useful photographic film base containing a miscible blend of is polyester containing at least 30 weight percent cyclohexylene dimethanol, CHDM/EG-PE, and a polycarbonate containing bisphenols, BP-PC, in specified proportions. Photographic elements prepared with this film base have a lesser tendency to take core-set and post process curl than do elements prepared with polyester containing cyclohexylene dimethanol, CHDM/EG-PE, film base.Type: GrantFiled: January 14, 1998Date of Patent: July 20, 1999Assignee: Eastman Kodak CompanyInventors: Dennis J. Massa, James M. O'Reilly, Wen-Li A. Chen

Patent number: 5922508Abstract: The invention describes a photopolymerizable recording material which comprises a photopolymerizable layer and a cover layer. The cover layer comprises a polymer which possesses low permeability to atmospheric oxygen and is soluble in water, and a water-soluble dye which absorbs light in the region from 300 to 700 nm and within this range has a non-absorbent region corresponding to the emission range of the copying light source.The material can be sensitized for various spectral regions, for example, for UV light, visible light or laser light and has a higher resolving power than a corresponding material which does not contain a dye in the cover layer, while its photosensitivity remains unchanged or is only slightly reduced.Type: GrantFiled: November 25, 1997Date of Patent: July 13, 1999Assignee: Agfa-Gevaert AGInventors: Rudolf Zertani, Dieter Mohr, Werner Frass
