Procedure
Following a procedure similar to that described in Example 4 but employing 4.0 g of 5-(dimethylamino)-2-[4-(ethylbenzylamino)benzoyl]benzoic acid and 2.2 g of 4-ethoxy-N-phenylaniline there was obtained 3.0 g of 6-(dimethylamino)-3-[4-(ethylbenzylamino)phenyl]-3-[(4-ethoxyphenyl)phenylamino]phthalide, m.p. 148°-152° C. A toluene solution of the product contacted with acidic clay or phenolic resin developed an orange-colored image which changed to green on clay after fluorescent light exposure.
