PIGMENTED POROUS MATERIAL

The present invention relates to a coloured, preferably natural porous material comprising in its pores an effectively colouring amount of an organic pigment which is obtained by fragmenting a meltable or solvent-soluble pigment precursor in the presence of a thermally activated acid precursor, and...

Beschreibung
Zusammenfassung:	The present invention relates to a coloured, preferably natural porous material comprising in its pores an effectively colouring amount of an organic pigment which is obtained by fragmenting a meltable or solvent-soluble pigment precursor in the presence of a thermally activated acid precursor, and to a low to medium temperature process for its preparation. L'invention concerne un matériau poreux, de préférence naturel, coloré, comprenant dans ses pores une dose efficace colorante d'un pigment organique que l'on obtient en fragmentant un précurseur de pigment, susceptible de fondre, ou soluble dans un solvant, en présence d'un précurseur d'un acide, activé par la chaleur. L'invention concerne également un procédé de préparation de ce matériau, dans des conditions de températures basses à moyennes.
