Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
49 words
A composition containing 10 to 60% of a liquid disperse dyestuff preparation, 30 to 55% of a liquid diffusion accelerant, 5 to 20% of an anionic or non-ionic emulsifying agent and 2,5 to 15% of a textile lubricant, the percentages being based on the total weight of the composition.
Claim 2
Dependent Claim
49 words
A composition containing 10 to 60% of a liquid disperse dyestuff preparation, 30 to 55% of a liquid diffusion accelerant, 5 to 20% of an anionic or non-ionic emulsifying agent and 2,5 to 15% of a textile lubricant, the percentages being based on the total weight of the composition.
Claim 3
Dependent Claim
52 words
A composition of claim 1, containing 15 to 50% of a liquid disperse dyestuff preparation, 30 to 50% of a liquid diffusion accelerant, 7 to 15% of an anionic or non-ionic emulsifying agent and 3 to 10% of a textile lubricant, the percentages being based on the total weight of the composition.
Claim 4
Dependent Claim
19 words
A composition of claim 1, in which the disperse dye is a low energy dye of low molecular weight.
Claim 5
Dependent Claim
14 words
