摘要

ABSTRACTA method is provided for temporary coloration of textile materialswhich comprises applying to said textile materials an amine-reducible tintin an amount sufficient to provide coloration to said textile material,said tint being characterized by the formula:R{A-[alkeneoxy constituent)nX]m}pwherein RA is the organic, easily reducible dyestuff radical, A is alinking moiety in said organic, easily reducible dyestuff radical selectedfrom the group consisting of -N-, -O-, -S-, or -CO2-, the alkenyl moiety ofsaid alkyleneoxy constituent contains from 2 to about 4 carbon atoms, n isan integer of from 2 to about 300, m is 1 when A is -O-, -S-, -CO2- and 2when A is -N-, p is an integer of from 1 to 5, and X is a member of thegroup consisting of -H-, -alkyl, -alkylcarboxylate, or -arylcarboxylate;and contacting said amine-reducible tint with an amine compound in anamount sufficient to reduce said tint whereby said coloration of saidtextile material is removed.
