Abstract: Techniques are described herein for selecting, curating, normalizing, enriching, and synthesizing the results of user experience tests. In some embodiments, a system identifies a qualitative element within a result set for a user experience test. The system then selects a machine learning model to apply based on one or more attributes associated with the user experience test and generates a predicted visibility, quality, and/or relevance for the qualitative element. Based on the prediction, the system generates a user interface that curates a set of results of the user experience test.

Abstract: The ever increasing demands on dispersants, emulsifiers and formulation aids, in particular in the preparation of azo dyes and pigments and in the preparation of dye and pigment dispersions, made it necessary to develop novel surface-active compounds.According to the invention, it has been possible by esterification of hydroxynaphthalenecarboxylic acids (on the carboxyl) with fatty alcohols or preferably with alkoxylates of fatty acids, resin acids or alkylphenols, condensation of the resulting esterification products with aldehydes to give novolak resins with subsequent alkoxylation and esterification of terminal OH groups with resin acids, fatty acids, aromatic carboxylic acids and hydroxylcarboxylic acids with or without reaction with phthalic anhydride or maleic anhydride and sulfite to develop novel polyfunctional surfactant structures which are very highly suitable for a wide range of applications in dispersion and emulsification, in particular in the preparation and formulation of azo pigments.
