The present invention relates to a branched modified polyetheramine polyol having a weight average molecular weight Min the range of ≥1000 g/mol to ≤100000 g/mol as measured by GPC, that is used as a universal dispersant for coating system, inks and color filters.

Dispersant for coating system

The invention relates to the use of a composition comprising a Cto Calkanol and a carboxylic acid ester of formula (I) wherein Ris selected from a Cto Calkyl, which may be unsubstituted or substituted by OH or F, and —X—[O—X]—H; Ris selected from a Cto Calkyl, which may be unsubstituted or substituted by OH or F, and —X—[O—X]—H; X, Xare independently selected from Cto Calkandiyl, which may be unsubstituted or substituted by OH or F; n is an integer from 1 to 5. wherein, the Cto Calkanol and the carboxylic acid ester are selected so as to form an azeotropic mixture and are present in an amount from 20% by weight below to 20% by weight above such azeotropic mixture.

Use of compositions comprising a solvent mixture for avoiding pattern collapse when treating patterned materials with line-space dimensions of 50 nm or below

The present invention relates to novel polymer compositions which are obtained by neutralizing a polymer P having at least one functional moiety of the formula (I) bound to at least one of the termini and/or to the backbone of the polymer, with an oligomeric or polymeric amine PA having at least 2 amino groups per oligomer or polymer molecule.

Polymer composition

An aqueous polymer dispersion with an average particle size of less than 1000 nm comprising a) a polymer carrier prepared by heterophase radical polymerization of at least one ethylenically unsaturated monomer in the presence of b) an oil-soluble organic UV absorber selected from the class of p-aminobenzoic acid derivatives; salicylic acid derivatives; benzophenone derivatives; diphenyl acrylate derivatives; benzofuran derivatives; polymeric UV absorbers, comprising one or more organosilicon radicals; cinnamic acid derivatives; camphor derivatives; s-triazine derivatives; trianilino-striazine derivatives; menthyl anthranilates; and benzotriazole derivatives; wherein the weight ratio of the oil-soluble organic UV absorber (b) to polymer carrier (a) is greater than 50 parts UV absorber per 100 parts of carrier; and c) a surfactant selected from c) a nonionic surfactant selected from c) the condensation product of a Cto Cfatty alcohol or Cto Cfatty acid and a mono- or disaccharide; and c) an anionic surfactant selected from c) sulfosuccinates and sulfosuccinamates; c) fatty alcoholates; and c) mixtures of phosphoric acid esters and fatty alcohols having from 6 to 18, preferably from 8 to 10, carbon atoms. The aqueous polymer dispersions show unexpectedly high sunscreen effects and a positive skin feeling. They have excellent anti-pollen, anti-dust and anti-oxidant performances in sun screen compositions.
