Procedure
The allylthiosalicylic acid (194 parts) was dissolved in 427 parts of methyl isobutyl ketone. To the solution was added 78 parts of mercaptoethanol, and the mixture was heated at 80° C. for 8 hours with stirring and with introduction of nitrogen gas to obtain a hydroxyethylthiopropylthiosalicylic acid solution containing about 39% of solids. To the solution (699 parts) thereafter cooled to 50° C. were added the following compounds, and the mixture was heated at 50° C. for 7 hours in a nitrogen gas atmosphere to obtain a monomer C solution.
