A J Ludlow Isoindolinone Yellow Professional Watercolour

Isoindolinone Yellow is just one of the bright and exquisite Professional Watercolours made in the UK by A J Ludlow. Being based on a single pigment with excellent permanence and light fastness, ensures that this watercolour’s properties are exceptional.

Isoindolinone Yellow Professional Watercolour is prepared using a red shade organic yellow pigment, from the azomethine-type isoindolinone class of high performance and heat stable pigments. This pigment has been selected for its red-shade hue, transparency and excellent light fastness. The isoindolinone pigments are part of the azo family of dyes and pigments derived from synthetic compounds that are characterised by the presence of one or more azo groups.

First discovered in 1946 and commercialised some 20 years later, the isoindolinone pigments are relatively new to the artists’ pallet and C.I. pigment yellow 110 is normally found in blended colours, rarely on its own. A J Ludlow’s Isoindolinone Yellow is a bright and intense red shade yellow which can be used on the artist’s palette as a warm primary yellow. It’s hue is similar to that of traditional Indian Yellow ( C.I. NY20).
