Development of Rapid Dry Photothermographic Materials with Water-base Emulsion Coating Method

摘要

The new system of the dry laser imager DRYPIX-7000 and the dry photothermographic imaging film DI-HL has been developed as a new generation of dry imaging system for health imaging. The system has the highest specifications, amazingly rapid output of first print (65 seconds), the highest throughput (180 sheets per hour for 14 × 17-in), and the shortest start up time (15 minutes from power off condition). These features were achieved by the combination of the excellent technologies introduced in the new imaging film and the laser imager. In DI-HL, new high-activity heat-developer and new heat-development accelerator were introduced in order to realize rapid processing and high throughput. Quite new yellow dye forming tone control agent was employed for excellent image tone reproduction. Image stabilizer, high purity silver behenate and new SBR latex binder were designed for image keeping stability. And the film is produced with water-base emulsion coating method, so much friendly to environment. In DRYPIX-7000 imaging apparatus, laser exposure and heat development are carried concurrently in order to realize high throughput.
