Procedure

A mixture iof 2.5 g of a 9:1 copolymer of methyl methacrylate and methacrylic acid, 3.50 g of Epocryl® DRH 303, 0.24 g of 2-(o-chlorophenyl)-4,5-diphenylimidazolyl dimer, and 0.06 g of Michler's ketone was dissolved in 25.20 g of 2-ethoxyethanol (Solution A). Solutions B, C and D were prepared by varying the quantities of Michler's ketone and 2-ethoxyethanol as follows:
