AI Technical Summary

Problems solved by technology

In the case of inorganic pigments, the use of large quantities of dispersion aids is limited due to the aid / pigment cost ratio
In addition, a high additive content leads to a corresponding reduction in color intensity and / or scattering power

Abstract

The invention relates to a dye preparation in pasty or gelatinovs denseness, comprising: one or a plurality of organic and / or inorganic colour(s) dispersed in the liquid; additional additive and / or bulking agent if necessary; dye preparation in pasty or gelatinovs denseness; not trending toward phase separation and not displaying any colouring effect on a dry and slick surface. The invention also relates to a method for manufacturing the dye preparation, comprising: providing one or a plurality of organic and / or inorganic colour(s) dispersed in the liquid, and additional additive and / or bulking agent if necessary; adding a combination of at least a thickening agent and / or at least a thickening agent and one or a plurality of compound(s) for strengthening the fixedness; homogenizing dye preparation in pasty or gelatinovs denseness for enough time; finally adding additional additive in proper. The dye preparation of the invention can process free of dust and cleanly with no problems.

Description

technical field The invention relates to paste-like or gel-like pigment preparations for coloring lime-bound and / or cement-bound building materials, bitumen, paints, varnishes, paper or plastics and also to a process for their preparation. Background technique The increase in colored patterns all around us in recent decades has caused a dramatic rise in the use of pigments. Since many colored materials include at least some inorganic pigments, the demand for them is also steadily increasing. Inorganic pigments are encountered in many areas of our daily life. They are used, for example, for coloring building materials such as concrete and asphalt, emulsion paints, varnishes, paper and plastics. Iron oxide pigments, the largest class of inorganic color pigments, have been used since prehistoric times. Cave paintings from Altamira (Spain) and Lascaux (France) around 15,000 years old provide evidence for the use of naturally occurring iron oxides as pigments. Ancient Egypt, ...
