Novel phthalocyanine compounds or salts thereof, which have hues suitable for ink-jet recording and are excellent in the light resistance and fastness of records and useful as black colorants or the like; ink compositions containing the same; methods for ink-jet recording by using the compositions; cases in which the compositions are put; ink-jet printers fitted with the cases; and products colored with the colorants. The novel phthalocyanine compounds or salts can be easily prepared by reacting an aminophthalocyanine with (meth)acrylic acid.

L'invention concerne de nouveaux composés de phtalocyanine ou leurs sels qui possèdent des teintes permettant de les utiliser dans l'impression à jet d'encre et qui permettent une vitesse d'impression élevée et manifestent une excellente résistance à la lumière; ils peuvent aussi s'utiliser comme colorants noirs ou similaires. L'invention concerne aussi des compositions qui les contiennent, des procédés d'impression à jet d'encre utilisant ces compositions, des récipients pour ces compositions, des imprimantes à jet d'encre munies de ces récipients et des produits colorés avec ces colorants. On peut facilement préparer ces nouveaux composés de phtalocyanine ou leurs sels en faisant réagir une aminophtalocyanine avec de l'acide (méth)acrylique.
