Abstract
Abstract Transfer printing supports impregnated or printed with a formulation containing a dyestuff of the formula I ##STR1## in which R 1 is alkyl having from 1 to 4 carbon atoms, R 2 is hydrogen or has the meaning of R 1 , R 3 is methyl, methoxy or ethoxy, and R 4 is hydrogen, methyl, methoxy or ethoxy, or containing mixtures of such dyestuffs, a process for the manufacture of these supports, which comprises impregnating or printing the support material with formulations containing a dyestuff of the formula I or mixtures of such dyestuffs, and the use of these supports for the dyeing and printing of flat web or sheet structures of synthetic or natural materials according to the heat transfer printing process.

A transfer printing support, impregnated or printed with a formulation containing the dyestuff of the formula ##STR6## in which R 1 is alkyl of from 1 to 4 carbon atoms, R 2 is hydrogen or alkyl of from 1 to 4 carbon atoms, R 3 is methyl, methoxy or ethoxy, and R 4 is hydrogen, methyl, methoxy or ethyoxy, or containing a mixture of dyestuffs of said formula.
Claim 3
Dependent Claim
45 words
A support as claimed in claim 1, impregnated or printed with a formulation containing a dyestuff of said formula in which R 1 and R 2 each is alkyl of from 1 to 4 carbon atoms, or containing a mixture of dyestuffs of said formula.
Claim 4
Dependent Claim
36 words
A support as claimed in claim 1 or 2, impregnated or printed with a formulation containing a dyestuff of said formula in which R 3 is methyl, or containing a mixture of dyestuffs of said formula.
