Abstract

Sulfonate dyes, particularly Alkali Blue R (Pigment Blue 19), are solubilized in octyl esters of oleic and linoleic acids and acrylates by adding oleyl amine in an amount stoichiometric to the dye. For adequate dispersion of a dye in liquid formulas to be solidified, the dye should be soluble in the formula and should not inhibit the solidification. Many dyes are largely neutral to solidification processes, but are not soluble in non-polar media. Where solidification is to be by ultraviolet or electron beam initiated polymerization (ionizing radiation curing), the system often will be non-polar. The oleyl amine is understood to complex with the acid functional group of Alkali Blue R dye, as shown in the drawing. Solubility of the complex occurs even in mineral oil.

Solubilizing Sulfonate Dyes in Non-Polar Media

Many dyes are largely neutral to solidification processes, but are not soluble in non-polar media. Where solidification is to be by ultraviolet or electron beam initiated polymerization (ionizing radiation curing), the system often will be non-polar. The oleyl amine is understood to complex with the acid functional group of Alkali Blue R dye, as shown in the drawing. Solubility of the complex occurs even in mineral oil. Solutions of the dye having appropriate polymerizable components, such as acrylates, cure readily under ionizing radiation.
