Colored ink They are more or less concentrated solutions of aniline dyes in water, to which a solution of shellac is added. The latter is introduced to give the ink the appropriate consistency, as well as to more firmly fix the dye on the paper. In addition, the shellac solution promotes indelibility.
Substantial and acidic dyes are used as dyes. Basic dyes are unsuitable for preparing mascara, as they are precipitated by an alkaline solution of shellac.
To increase the resistance of the carcass to water, it is recommended to add a small amount of ammonia salts. An example for making colored ink is the following recipe:
- Shellac 30 g;
- Borax 20 g;
- Water 925 cm3;
- Dye 12-18 g.
Dissolve borax in 225 cm3 of boiling water, after which shellac is diluted in the resulting solution. Separately, dilute the dye in the remaining 700 cm3 of water and add it to the first solution.
Aniline firmly red F, Anilviolet N, Aniline green B, Aniline blue RV, etc. are used as a dye.

Artificial leather for touch emulation
15.04.2024
In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men
14.04.2024
The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>
| Random news from the Archive Exercise saves chromosomes
01.11.2008
According to the existing theory, the lifespan of a cell is determined by the tips of chromosomes, the so-called telomeres. With each division, they shorten a little. Finally, there comes a point when the telomeres are so shortened that the cell can no longer divide and dies.
The results of a study conducted at King's College London show that physical education slows down the destruction of chromosomes and aging of cells.
Physiologists examined 67 pairs of twins, in which one brother is engaged in physical education, and the other is not. It turned out that the chromosomes of active people look 10 years younger than those of sedentary people.
