Abstract
Abstract Fugitive tints are provided which are characterized by the formula: ##STR1## where R is selected from meta-toluidene, meta-amino phenol, aniline or dimethoxy aniline A is selected from N, O, S, or CO 2 ; the alkylene group of the alkyleneoxy constituent contains from 2 to about 4 carbon atoms; n is an integer of from 2 to about 300; m is 1 when A is O, S, or CO 2 , and 2 when A is N; x is an integer of from 1 to about 5; and the product of n times m times x (n·m·x) is from 2 to about 400. Also provided is a process for preparing alkyleneoxy fugitive tints.
