The invention relates to a dispersible pigment concentrate, in particular for coloring of cement based building materials like concrete, and for coatings, paints and the like, that contains at least one pigment as well as, if necessary, bonding, dispersion and wetting agents, with a content of a disintegration agent, which, when contacting water (in sufficient amount), causes an essentially complete disintegration of the primary structure of the concentrate with subsequent release the pigment particle within one minute without any mechanical operation.
La présente invention se rapporte à un concentré de pigment dispersable, destiné en particulier à colorer des matériaux de construction à base de ciment tels que le béton, et à des revêtements, peintures et analogues. Ledit concentré de pigment contient au moins un pigment et, si nécessaire, des agents liants, dispersants et mouillants, ainsi qu'une dose d'un agent de désintégration qui, lorsqu'il est mis au contact de l'eau (en quantité suffisante), provoque la désintégration sensiblement complète de la structure primaire du concentré, ce qui libère ensuite la particule pigmentaire, en l'espace d'une minute et sans aucune opération mécanique.
