Patent
CA 2286677
The present invention relates to a coloured porous material comprising in its pores an effectively colouring amount of an organic pigment which is obtainable by fragmenting a meltable or solvent-soluble pigment precursor, and to a process for its preparation. The present invention also relates to the use of the instant coloured porous material powders as pigments for high molecular weight organic materials.
La présente invention concerne une matière poreuse colorée comprenant dans ses pores une quantité colorante efficace d'un pigment organique que l'on peut obtenir en fragmentant un précurseur de pigment qui peut fondre ou est soluble dans un solvant. Elle concerne également un procédé de préparation de cette matière, de même que l'utilisation de poudres instantanées à base de matières poreuses colorées, en tant que pigments destinés à des matières organiques à masse moléculaire élevée.
