This invention provides methods and technology related to increased hiding power of a coating through mediating the interaction of the pigment with other system components including but not limited to other pigment particles, latex paint particles, latex binding particles, and organic or inorganic hollow particles. Organization and spacing are tailored via pH sensitive functionalities hosted on ligands or polymeric spacers that are located at/within the surface of one of the components.

Tailored dispersion and formation of integrated particle systems via pH responsive groups

Disclosed is a thermoplastic melt-mixed composition including: a) a polyamide resin; b) 0.50 to about 5.0 weight percent of one or more amino acid selected from the group consisting of primary amino acids and secondary amino acids; said amino acid having no hydroxyl groups and no more than one carboxylic acid; optionally, c) one or more polyepoxy compound including at least two or more epoxy groups; d) reinforcing agent; e) polymeric toughener; and f) further additives; wherein the weight percents of components a), b), c) d) e) and f) are based on the total weight of the thermoplastic melt-mixed composition. Also disclosed are processes for making the compositions.
