Abstract
Abstract A process for printing flat-surface structures of manmade or regenerated polymer materials by the transfer printing process, which comprises the use of dyes of the formula ##STR1## wherein X represents hydrogen, halogen, or a lower alkylsulphone group, Y represents hydrogen, chlorine, bromine, nitro, cyano, or an alkyl group of 1 to 4 carbon atoms, Z represents hydrogen, chlorine, nitro, an acylamino group, or a lower alkylsulphonyl group, R represents an alkyl radical of 1 to 4 carbon atoms, and R 1 , R 2 and R 3 , each independently of the other, represent an alkyl radical of 1 to 4 carbon atoms, a cycloalkyl radical of 5 to 7 carbon atoms, an aralkyl or an aryl radical.

Total Claims: 12
Claim 1
Independent Claim
190 words
In the process for the transfer printing of flat-surface structure of synthetic polymer materials which comprises bringing a support printed with a suitable printing ink into close contact with the flat-surface structure to be printed and applying heat, pressure or both heat and pressure to cause dyestuff to be transferred from the support to the flat-surface structure by diffusion and sublimation, the improvement according to which the printing ink printed on the support comprises at least one dyestuff of the formula ##STR37## wherein X represents hydrogen, halogen, or a lower alkylsulphone group, Y represents hydrogen, chlorine, bromine, nitro, cyano, or an alkyl group of 1 to 4 carbon atoms, Z represents hydrogen, chlorine, nitro, an acylamino group, or a lower alkylsulphonyl group, R represents an alkyl radical of 1 to 4 carbon atoms, and R 1 , R 2 and R 3 , each independently of the other, represent an alkyl radical of 1 to 4 carbon atoms, a cycloalkyl radical of 5 to 7 carbon atoms, an aralkyl or an aryl radical and the flat-surface structure is composed of synthetic polymer material having affinity for the thus transferred dyestuff.
