Latest Patents

One of Masuda's latest patents is for an inkjet recording ink. This invention aims to provide an ink that excels in storage stability and discharge stability while achieving high coloration on both regular and gloss paper. The ink composition includes water and a pigment dispersed using a polymer, which is created by polymerizing at least 50% by weight of benzylacrylate and 15% or less of (meth)acrylic acid. The polymer has an acid value ranging from 50 mgKOH/g to 120 mgKOH/g and a weight average molecular weight between 10,000 and 120,000.

Another notable patent is for an ink composition that contains a specific anthrapyridone dye and a particular copper phthalocyanine dye. The hue angle in the L*a*b* color system, calculated from the spectral characteristics of a 1,000-fold diluted solution of the ink composition in water, ranges from 270° to 360°. In this composition, the content of the anthrapyridone dye is greater than that of the copper phthalocyanine dye.
