Translation of "Farbaufbau" in English

This favors a so-called ink build-up on the first rollers.

The result is a uniformly deeply orange pattern showing excellent color build-up.

The compound according to the invention also exhibits a good color buildup.

The weighting corresponds to the coefficients of surface coverage of the color in the color structure of the sample.

Even when used for deep navy dyeings, the dye mixture shows good bath exhaustion and good build-up.

Even in textile printing the use of dyestuffs according to the invention produces a somewhat more favorable color build-up.

The customary padding processes likewise provide excellent color yields and very good color build-up on cellulose fibers.

The compound according to the invention furthermore is distinguished by a high degree of fixation and very good color buildup.

They have a very good color buildup where the brillant hue is retained in deep shades.

No complex colour structure seduces the viewer to perceive film and/or adhesive tape.

Wrede): sand blasted, new 2K paint build-up in the spraying process, indicator coating u.

Thus, very good color yields and an excellent color build-up are obtained with them on cellulose fibers by the exhaustion process using the most diverse acid-binding agents and, if necessary, with the addition of neutral salts, such as sodium chloride or sodium sulfate.

In respect of the coloristic properties of the compounds according to the invention, it should be particularly emphasized that they are distinguished by a good stability in printing pastes and padding liquors, even in the presence of alkali, by a very good affinity from a long liquor, by a good color build-up when used in customary dyeing and printing processes, by the same depth of color in the dyeing of cotton and regenerated cellulose fibers, by a level appearance of the dyeings and prints produced with them, and also by a uniform quality of dyeings obtained from a long liquor with the addition of various amounts of electrolytes.

Thus, using these dyestuffs, very good color yields and an excellent build-up of color are obtained on cellulose fibers in the exhaustion process from a long-liquor bath in the presence of an acid-binding agent and, if appropriate, neutral salts, such as sodium chloride or sodium sulfate.

Compared to the dyestuffs described in German Pat. No. 1,179,317, Example 1, and in German Pat. No. 2,824,211, Example 1, the dyestuff according to the invention was distinguished by the fact that full color build-up was obtained with the dyestuff in the short-time pad method after only 4 hours, while in the case of the known dyestuffs between 12 and 24 hours were necessary for this.

When dyeing using the exhaust method, a color build-up which was about 20 to 30% higher than for the already known dyestuffs was obtained by means of dyestuff according to the invention.

In trichromatic dyeing or printing, the dyes employed in the process of this invention are distinguished by level colour build-up, good exhaustion properties, good constancy of shade even in different concentrations, good fastness properties, as well as in particular by very good compatibility.

Thus, by the exhaustion processes from long liquor with the use of an acid-binding agent and, if appropriate, neutral salts, such as sodium chloride or sodium sulfate, they give very good color yields and an excellent color build-up on cellulose fibers.

The padding process likewise gives excellent color yields and a very good color build-up on cellulose fibers and, in this case, fixation can be carried out by leaving the material to stand at room temperature or at an elevated temperature, for example up to about 60° C., by steaming or by means of dry heat in the conventional manner.

These devices do not take into account the fact that the ink build-up occurs only at very limited points which exhibit great differences in the ink locally, for example when printing a frame around a picture.

Unlike structurally similar known dyestuffs they surprisingly have a very good color buildup, the brillant hue being retained in deep shades.

For instance, if applied to cellulose fibers by the exhaustion methods from long liquor using all manner of acid-binding agents and optionally neutral salts, such as sodium chloride or sodium sulfate, they produce very good color yields and an excellent color buildup.

To achieve an advantageous build-up of color, it may be advantageous in some cases to use mixtures of the novel dyes of formula I for dyeing.

In particular, the dyeings obtained are distinguished by uniform colour build-up, while at the same time having consistency of shade in different concentrations, and by their very good compatibility on the dyed material, and the prints are free from two-sidedness, i.e. the prints have consistency of shade.

The monoazo compounds (1) according to the invention are distinguished by a good water-solubility and a good color build-up.

The degree of fixing and the color build-up are very high, and the prints are obtained with a clear white background.

The dyes used in the process according to the invention are distinguished in trichromatic dyeing or printing by a uniform colour buildup, good affinity, good constancy of shade even in different concentrations, good fastness properties and in particular very good compatibility.

The dyes used in the process according to the invention are distinguished in trichromatic dyeing or printing by a uniform colour build up, good affinity, good constancy of shade, even in different concentrations, good fastness properties and in particular by very good compatibility.

When used for trichromatic dyeing or printing, the dyes of formula (1) and the dyes used in the process of the invention are distinguished by uniform build-up, good affinity, good consistency of shade, even at different concentrations, good fastness properties as well as in particular very good compatibility.
