Title: The Innovative Contributions of Gerardus J. Crommentuyn

Introduction

Gerardus J. Crommentuyn, an innovative inventor based in Lottum, Netherlands, has made significant strides in the field of toner powder technologies. With a total of six patents to his name, his work primarily focuses on enhancing the development of latent electrostatic and magnetic images through advanced materials and processes.

Latest Patents

Among his latest patents, one notable invention is a toner powder designed for the development of latent electrostatic or magnetic images. This toner powder comprises a polyester resin that is based on an etherified diphenol and a dicarboxylic acid. It is mixed with a reaction product of an epoxy resin and a phenol compound or a carboxylic acid. The innovation lies in the process for forming fixed images on an image receiving material, employing an intermediate medium that has a lower affinity for the softened toner powder. This medium facilitates the softening of toner powder through heating during its transit to a pressure zone.

Another important patent revolves around the development of a colored magnetically attractable toner powder, which also serves in the creation of latent electrostatic or magnetic images. This toner powder features particles that consist of a magnetically attractable core, which is ideally spherical and composed of particulate magnetically attractable material or a dispersion of such material within a binder. A masking layer surrounds the core, incorporating a binder mixed with light-reflecting pigments of submicron size, along with a coloring material applied in and/or onto the masking layer. The processes for preparing this toner powder are critical, as they contribute to developing latent image patterns.
