发明名称 NON-AQUEOUS PIGMENTED INKJET INKS
摘要 <p>A non-aqueous inkjet ink containing a pigment comprising C.I. Pigment Violet 19 and a polymeric dispersant according to Formula (I) wherein, T represents hydrogen or a polymerization terminating group; Z represents the residue of polyethyleneimine having a number-average molecular weight of at least 100; A represents an oxyalkylene carbonyl group; T-C(O)A&lt;SUB&gt;n&lt;/SUB&gt;- represents a TPOAC-chain which is bound to Z through an amide bond; and n and m are integers wherein m is at least 2 and n is from 2 to 100; characterized in that the polymeric dispersant fulfills the conditions of: W&lt;SUB&gt;TPOAC&lt;/SUB&gt; &gt; 57 and N&lt;SUB&gt;Amide&lt;/SUB&gt; = 65 mol% with W&lt;SUB&gt;TPOAC&lt;/SUB&gt; representing the ratio of the weight percentage of TPOAC-chains over the weight percentage of amide bonds in the polymeric dispersant; N&lt;SUB&gt;Amide&lt;/SUB&gt; representing the mol% of amide bonds based on the total nitrogen content of the polymeric dispersant; and wherein the values of W&lt;SUB&gt;TPOAC&lt;/SUB&gt; and N&lt;SUB&gt;Amide&lt;/SUB&gt; are calculated from the total nitrogen content determined by dry combustion of the polymeric dispersant and from the amine content determined through potentiometric titration in a mixture of CH&lt;SUB&gt;3&lt;/SUB&gt;COOH:THF (14.5:0.5) with 0.1 N aqueous perchloric acid.</p>
