(I; R, R1 = C1-4 alkyl) are color formers exhibiting good color intensity, good sublimation resistance, and good soly. in petroleum distillate solvents. Thus, I (R = R1 = Me) [83757-32-8], prepd. by reaction of (4-Et2NC6H4)2CHOH [134-91-8] with Me2C:NOH [127-06-0] in refluxing MEK-hexane contg. MeSO3H, was sol. at 4% in kerosine and showed image color intensity 1.35 (Crystal Violet = 1.0) and only a trace of sublimation (ghosting) (16 h at 145-150 °F) when treated on color former paper. Analogs of I with Me2N instead of Et2N groups and/or with R and R1 other than C1-4 alkyl exhibited lower intensity, moderate sublimation, and/or insoly. in kerosine. .
