60 g. of intermediate (A) and 20 g. of acrylic acid were diluted in 120 cc. of ethanol in a flask with stirrer and reflux and 2 g. of lauroyl peroxide were added, and then reflux heated. After one hour, 16 g. of acrylic acid and 1 g. of lauroyl peroxide diluted in 20 g. of ethanol were added; always continuing the reflux heating, at one hour time intervals the following additions were made: 13 g. of acrylic acid and 1 g. of lauroyl peroxide in 20 cc. of ethanol; 10 g. of acrylic acid and 0.8 g. of lauroyl peroxide in 15 cc. of ethanol; 8 g. of acrylic acid and 0.8 g. of lauroyl peroxide in 10 cc. of ethanol. After the last addition the mixture was refluxed for two hours, then it was cooled, and precipitated in ethyl ether; the precipitate was recovered on filter, washed with ether and vacuum dried at 50° C. The yield was 49 g. of a product containing about 23% of aminoallylidenemalononitrile units. The product was water and NaOH at pH=7 soluble. A solution at 6% 1:9000 diluted with water, had an optical density of 0.46.
