The compounds of this invention are suitable matting agents for coatings. The compounds are amide-containing condensation products optionally comprising at least one β-hydroxyalkylamide functional group and, for example, are prepared from monomeric amides, oligomeric polyamides or polymeric polyamides bearing β-hydroxyalkylamide groups by reacting the hydroxyalkylamide bearing amide with another compound such that at least one reactive functional group other than β-hydroxyalkylamide is also present on the condensation product, and further such that 50% or more of the terminal β-hydroxyalkylamide functionality has been reacted or converted to groups containing terminal carboxylic acid groups or other reactive groups including, but not limited to, groups reactive with polymers and crosslinkers suitable for preparing epoxy, epoxy-polyester, polyester, polyester acrylic, polyester-primid, polyurethane or acrylic coatings. Other embodiments of the invention comprise the combination of the aforementioned condensation product with inorganic solids such as silicas and aluminas, and/or matte activators.
本发明的化合物是适用于涂料的消光剂。这些化合物是含酰胺的缩合产物,可选择包含至少一个 β-羟基烷基酰胺官能团,例如,由含有 β-羟基烷基酰胺基团的单体酰胺、低聚多酰胺或聚合物多酰胺制备,方法是将含有羟基烷基酰胺的酰胺与另一种化合物反应,使缩合产物上也存在至少一个除 β-羟基烷基酰胺外的反应性官能团、进一步使 50%或更多的端β-羟基烷基酰胺官能团反应或转化为含有端羧酸基团或其他反应性基团的基团,包括但不限于与适合制备环氧树脂、环氧-聚酯、聚酯、聚酯-丙烯酸酯、聚酯-丙烯酸酯、聚氨酯或丙烯酸涂层的聚合物和交联剂反应的基团。本发明的其他实施方案包括上述缩合产物与无机固体(如硅和铝)和/或哑光活化剂的组合。
