Total Claims: 7
Claim 1
Independent Claim
159 words
FROM 95 TO 99.95% BY WEIGHT, BASED ON THE COPOLYMER, OF ACRYLIC ACID AND/OR METHACRYLIC ACID; AND B. FROM 10 TO 80% BY WEIGHT, BASED ON THE MIXTURE OF (A), MONOMER HAVING TWO ISOLATED DOUBLE BONDS AND FROM SIX TO FOURTEEN CARBON ATOMS, B. FROM 10 TO 80% BY WEIGHT, BASED ON THE MIXTURE OF (A), (B) AND (C), OF AN ORGANIC LIQUID WHICH DOES NOT DIS, SOLVE THE COPOLYMER (A), WHICH BOILS AT ABOVE 130*C AND WHICH PRIOR TO BEING MIXED WITH COMPONENTS (A), AND (C) CONTAINS LESS THAN 2% BY WEIGHT OF WATER, BASED ON THE LIQUID; AND C. FROM 0.5 TO 50% BY WEIGHT, BASED ON THE MIXTURE OF (A), (B) AND (C), OF A NONIONI OR ANIONIC EMULSIFIER, THE CARBOXYL GROUPS OF THE COPOLYMER (A) HAVING BEEN NEUTRALIZED BEFORE OR DURING THE PREPARATION OF THE PRINT PASTE, AND B. THEREAFTER HEATING SAID PRINTED MATERIAL TO FIX AND DYE WITHOUT INTERMEDIATE DRYING OF THE PRINT PASTE.

FROM 95 TO 99.95% BY WEIGHT, BASED ON THE COPOLYMER, OF ACRYLIC ACID AND/OR METHACRYLIC ACID; AND B. FROM 10 TO 80% BY WEIGHT, BASED ON THE MIXTURE OF (A), MONOMER HAVING TWO ISOLATED DOUBLE BONDS AND FROM SIX TO FOURTEEN CARBON ATOMS, B. FROM 10 TO 80% BY WEIGHT, BASED ON THE MIXTURE OF (A), (B) AND (C), OF AN ORGANIC LIQUID WHICH DOES NOT DIS, SOLVE THE COPOLYMER (A), WHICH BOILS AT ABOVE 130*C AND WHICH PRIOR TO BEING MIXED WITH COMPONENTS (A), AND (C) CONTAINS LESS THAN 2% BY WEIGHT OF WATER, BASED ON THE LIQUID; AND C. FROM 0.5 TO 50% BY WEIGHT, BASED ON THE MIXTURE OF (A), (B) AND (C), OF A NONIONI OR ANIONIC EMULSIFIER, THE CARBOXYL GROUPS OF THE COPOLYMER (A) HAVING BEEN NEUTRALIZED BEFORE OR DURING THE PREPARATION OF THE PRINT PASTE, AND B. THEREAFTER HEATING SAID PRINTED MATERIAL TO FIX AND DYE WITHOUT INTERMEDIATE DRYING OF THE PRINT PASTE.
Claim 3
Dependent Claim
137 words
from 5 to 0.05% by weight of a copolymerizable monomer having two isolated double bonds and from six to fourteen carbon atoms, b. from 10 to 80% by weight, based on the mixture of (a), (b) and (c), of an organic liquid which does not dissolve the copolymer (a), which boils at above 130*C and which prior to being mixed with components (a) and (c) contains less than 2% by weight of water, based on the liquid; and c. from 0.5 to 50% by weight, based on the mixture of (a), (b) and (c), of a nonionic or anionic emulsifier, the carboxyl groups of the copolymer (a) having been neutralized before or during the preparation of the print paste, and B. thereafter heating said printed material to fix and dye without intermediate drying of the print paste.
Claim 4
Dependent Claim
137 words
from 5 to 0.05% by weight of a copolymerizable monomer having two isolated double bonds and from six to fourteen carbon atoms, b. from 10 to 80% by weight, based on the mixture of (a), (b) and (c), of an organic liquid which does not dissolve the copolymer (a), which boils at above 130*C and which prior to being mixed with components (a) and (c) contains less than 2% by weight of water, based on the liquid; and c. from 0.5 to 50% by weight, based on the mixture of (a), (b) and (c), of a nonionic or anionic emulsifier, the carboxyl groups of the copolymer (a) having been neutralized before or during the preparation of the print paste, and B. thereafter heating said printed material to fix and dye without intermediate drying of the print paste.
Claim 5
Dependent Claim
28 words
A process as set forth in claim 1, wherein the dye is fixed by heating the textile at about 100* to 220* C with hot air or steam.
Claim 6
Dependent Claim
25 words
A process as set forth in claim 1, wherein the amount of thickener is from 1 to 3% by weight based on the print paste.
Claim 7
Dependent Claim
53 words
A process as set forth in claim 1, wherein the amount of (b) is from 20 to 70% by weight based on the weight of the mixture of (a), (b) and (c) and the amount of (c) is from 5 to 30% by weight based on the mixture of (a), (b) and (c).
