Problems solved by technology

However, the use of inorganic salts of rosin (Kolophoniumharzen) to improve the structure of the pigments, on the one hand they can remain in the pigment preparation, leading to defects in organic coatings
On the other hand, the state of dispersion is not optimal, so that, for example, with phthalocyanine dyes, several wet grindings must be carried out

Embodiment

[0112] 1) Preparation of polyoxyalkylenes containing styrene oxide (component B)i), not according to the invention 336.4 g (2.34 mol) of trimethylcyclohexanol and 16.3 g (0.23 mol) of potassium methoxide were charged to the reactor. After careful flushing with pure nitrogen, the starting material was heated to 110° C. and 308.2 g (2.554 mol) of styrene oxide were added within one hour. After another two hours, the addition reaction of styrene oxide was completed, and according to the gas chromatogram, it was proved that the reaction was completed by the residual styrene oxide content < 0.1% by weight. Then 339.2 g (7.71 mol) of ethylene oxide were fed into the reactor at such a rate that the internal temperature did not exceed 120°C and the pressure did not exceed 6 bar. After complete addition of ethylene oxide, the temperature was controlled at 115° C. until the pressure on the manometer indicating the end of the subsequent reaction was constant. Finally, unreacted residual...

Abstract

The invention relates to solid or liquid universal pigment compounds, consisting of at least one pigment and one resin, their production process, and their utilization in paints, varnishes, adhesives, inks, or printing colors.

Description

technical field [0001] The present invention relates to universal pigment preparations consisting of at least one pigment and one resin, and also to a process for their production and their use in paints, coatings, adhesives, inks or printing inks. Background technique [0002] These pigment preparations are used in coatings such as, for example, paints, coatings, adhesives, inks or printing inks when coating objects made, for example, of metal and plastics. These coating compositions are suitable for all usual coating methods used in modern metal and plastic coating as well as in the printing ink industry, such as coating methods by spraying, electrostatic spraying, but also printing with various printing methods . [0003] Usually, color coatings are produced by first producing liquid pigment preparations, which are then blended in with the base paint (Stammlack). [0004] During the production of pigment preparations, fillers and pigments are dispersed in a liquid mediu...
