실험 절차

A solution of 15 g of a 9:1 copolymer of methyl methacrylate and methacrylic acid in 30 g of 2-butanone was prepared by warming at 45° for 0.5 hr. To this solution was added 90 g of 2-ethoxyethanol, 15 g of Epocryl® 12, 1.2 g of 2-o-chlorophenyl-4,5-diphenylimidazolyl dimer, 0.9 g of Michler's ketone, 0.06 g of Leuco Crystal Violet, 0.30 g of C.I. Solvent Red Dye #109 and 10 g of methyl chloroform, and the mixture was dissolved by rolling for 1 hour. After standing overnight the solution was filtered, and it was spin-coated onto a 15×20 inch (38.1×50.8 cm) anodized aluminum substrate (275 rpm for 2.0 minutes). The coated plate was air-dried at 100° for 5 minutes to give a coating weight of 68.6 mg/dm2. The plate was exposed through a process transparency for 1.0 minute to a Xenon flash lamp under vacuum to give good contact with the process transparency. (A Xenon flash Nu Arc plate maker was employed at 1 mm pressure; GEPXA Xenon bulb with 2500 watt input at a distance of 16.5 inches (42 cm) from the photopolymerizable layer was used.) The exposed plate was developed for 15 seconds with the development solution of Example 1, and a printing press was used to print 5000 copies from this lithographic plate. Excellent prints were obtained with no evidence of plate wear, and excellent dot size reproduction was also obtained.
