The invention relates to the use of polybasic acids as gloss reduction agents in the preparation of paint or coating compositions based on hydroxy or phenolic functional resins and also containing an amino cross-linking agent and a pigment. Cured coatings exhibiting good flexibility, hardness and solvent resistance, as well as reduced or controllable gloss are obtained.
l'invention se rapporte à l'utilisation d'acides polybasiques comme agents atténuant la brillance dans la préparation de compositions pour peinture ou revêtement à base de résines fonctionnelles hydroxy ou phénoliques, et contenant également un agent de réticulation amino et un pigment. On obtient ainsi des revêtements durcis, présentant une bonne flexibilité, une bonne dureté et une bonne résistance aux solvants, ainsi qu'une brillance atténuée ou modulable.
