Triarylmethane compounds used as antioxidants in overcoat layers to alleviate printing defects and an improved chemical process for the synthesis of these triarylmethane compounds using an acetal derivative of an aldehyde which significantly reduces reaction time and results with the formation of substantially no byproducts.

Triarylmethanes and processes for making the same

A process for manufacturing a toner having improved relative humidity sensitivity is described. The process comprises forming polyester toner particles by emulsion/aggratation, fluidizing the toner particles with a stream of inert gas while spraying the toner particles with a solution containing an additive affecting relative humidity sensitivity, and wherein the additive contacts a surface of the toner particles and the additive remains on the surface of the toner particles.
