Abstract
Disclosed is a method of printing a cellulose fiber material with a reactive dye or direct dye, which comprises printing the cellulose fiber material with a printing paste containing an emulsion formed by emulsifying a mixture comprising a hydrophobic substance liquid at room temperature, represented by the following general formula I: ##STR1## wherein R.sub.1 and R.sub.2 independently represent a hydrogen atom or an acyl group derived from a saturated or unsaturated monoaliphatic carboxylic acid having 2 to 22 carbon atoms, R.sub.3 and R.sub.4 independently represent a methyl group, an ethyl group or a phenyl group, and l and m represent zero or a positive integer, with the proviso that the sum of l and m is an integer of from 1 to 300 and when each of R.sub.1 and R.sub.2 is a hydrogen atom, the sum of l and m is an integer of from 6 to 300, and a hydrophobic substance solid at room temperature, represented by the following general formula II: EQU A(OR.sub.5).sub.n II wherein A represents a residue of a trihydric to hexahydric alcohol, R.sub.5 represents an acyl group derived from a saturated or unsaturated fatty acid having 12 to 22 carbon atoms, and n is an integer of from 1 to …
