[EN] The present invention relates to improved substrates for use with colorants, and especially with a family of colorants and colorant stabilizers. The colorant stabilizers, according to the present invention, are capable of stabilizing a colorant when it is exposed to electromagnetic radiation. The colorant stabilizers enable the production of an ink set wherein each ink of the ink set, regardless of color, possesses substantially similar light fastness properties. The present invention further relates to improved substrates for use with colorants, and especially with the colorants and colorant stabilizers of the present invention. The improved substrates enable the production of a printed substrate having superior print quality compared to conventional substrates. [FR] Substrats améliorés destinés à être utilisés avec des colorants, en particulier avec une famille de colorants et de stabilisateurs de colorants. Selon l'invention, les stabilisateurs de colorants peuvent stabiliser un colorant exposé au rayonnement électromagnétique. Les stabilisateurs de colorants permettent de produire une série d'encres, où chaque encre, indépendamment de la couleur, a des propriétés de solidité à la lumière sensiblement analogues. On décrit aussi des substrats améliorés destinés à être utilisés avec des colorants, en particulier avec les colorants et stabilisateurs de colorants considérés dans l'invention. Les substrats améliorés permettent de produire un substrat imprimé dont la qualité de l'impression est supérieure à celle des substrats classiques.

The present invention relates to a family of new porphine compounds for use as colorants and/or colorant stabilizers. The new porphine compounds may be used alone or may be used in combination with one or more colorants to provide light stability to colorants. The present invention further relates to inks containing the new porphine compounds and a method for making the new compounds. The present invention also relates to improved methods of making porphines. The improved processes allow the production of porphines at lower cost and higher yields compared to conventional methods of making porphines.
