Patent number: 5665522Abstract: Positive-acting no-process printing plates are disclosed in which a stable visual or print-out image is obtained upon exposure of the plate to actinic radiation. The visual image is obtained by incorporation into the photosensitive layer, a dye which is irreversibly bleached upon exposure of the printing plate. For example, an acid which is generated upon exposure of a photopolymer to radiation may be used to bleach a dye of this invention. The visual or print-out images produced are useful in the production cycle and are stable to basic environments that may be encountered in the production setting.Type: GrantFiled: May 2, 1995Date of Patent: September 9, 1997Assignee: Minnesota Mining and Manufacturing CompanyInventors: Dennis E.
