A universal pigment preparation including a flocculation-stabilizing medium including (a1) reaction products of di- or polycarboxylic acids or hydroxycarboxylic acids with di- or polyols, and (a2) reaction products of alkylene oxides with alkoxylatable compounds, and at least one pigment. Paints, varnishes, printing inks, coating materials, floor coatings, potting compounds and filling compounds may be made using the universal pigment preparation.

Universal pigment preparation

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 polyester resin, comprising a polyester which comprises as esterified polymer units: at least one of an unsaturated dicarboxylic acid and an unsaturated polycarboxylic acid; and at least one of an alkoxylated diol and an alkoxylated polyol is provided. An adhesion-promoting additive comprising the polyester resin is also provided.

Liquid, adhesion-promoting additive and process for its preparation

The invention relates to tin-free reaction products of hydroxyl-containing hydrogenated ketone resins, carbonyl-hydrogenated ketone-aldehyde resins, and carbonyl-hydrogenated and ring-hydrogenated ketone-aldehyde resins based on aromatic ketones and polyisocyanates, to a process for their preparation and to the use thereof, in particular as a main component, base component or additive component in coating materials, adhesives, inks, polishes, glazes, stains, pigment pastes, filling compounds, cosmetics articles, sealants and/or insulants.

Tin-free, high-melting reaction products of carbonyl-hydrogenated ketone aldehyde resins, hydrogenated ketone resins, and carbonyl-hydrogenated and core-hydrogenated ketone aldehyde resins based on aromatic ketones and polyisocynates

The invention described herein provides ketone-aldehyde resins, especially cyclohexanone-formaldehyde resins, with low water content and high thermal stability and yellowing resistance, and to a process for preparing them and their use.

Ketone-aldehyde resins having low water content, high thermal stability and yellowing resistance

A low-viscosity polyisocyanate of reduced color, containing isocyanurate groups is prepared by partially trimerizing an aliphatic and/or cycloaliphatic diisocyanate in the presence of 0.02 to 2% weight, based on the weight of the diisocyanate starting material, of at least one trimerization catalyst containing a quarternary amine component and then removing excess diisocyanate from the reaction medium.

Catalyst and process for preparing low-viscosity and color-reduced polyisocyanates containing isocyanurate groups
