A functionalized ketone-aldehyde condensation resin is produced by condensing a ketone and an aldehyde in the presence of at least one alcohol or alkoxylate thereof, wherein the alcohol comprises amino alcohols and derivatives thereof, hydroxybutyl vinyl ether, OH-functional acrylates, OH-functional terpenes, OH-functional halogen compounds, hydroxycarboxylic acids, sulphur-containing alcohols, hydroxyl-containing urea derivatives, carbohydrates, siloxanes, OH-functional phosphorus compounds or unsaturated alcohols.

Functionalized ketone-aldehyde condensation resins

A dispersing resin for conventional solventborne pigment preparations having a low to very low proportion of volatile organic substances is provided. Further provided are solventborne coating materials containing the dispersing resin. Uses include paints, varnishes, adhesives, inks or printing inks, and compositions for coloring of plastics. The pigment preparations produced with these resins are free of yellowing, stable to weathering, of low viscosity and intensely colored.

Dispersing resins for pigment preparations having a low volatile organic content

A resin is based on ketones and aldehydes and is prepared in methanol or ethanol in the presence of a phase transfer catalyst. The resin features a very broad solubility and low intrinsic color.
