Title: Michel Ernest Huille: Innovator in Phthalocyanine Pigments

Introduction

Michel Ernest Huille is a notable inventor based in Creil, France. He has made significant contributions to the field of chemistry, particularly in the development of stable phthalocyanine pigments. With a total of five patents to his name, Huille's work has had a lasting impact on the industry.

Latest Patents

Huille's latest patents include a process for the preparation of phthalocyanine pigments. This innovative process improves the stability of copper phthalocyanine pigment against crystallization. The method involves dry grinding crude copper phthalocyanine without any mineral substrate or crystallizing solvent. This results in a ground phthalocyanine of non-pigmentary or feebly pigmentary character. The ground phthalocyanine is then treated with a crystallizing solvent in the presence of a stabilizing compound. The concentration of the stabilizing compound ranges from 1% to 25% of the weight of the phthalocyanine. Additionally, he has developed pigmentary compositions in the form of powder or pigmented paste obtained through this process. His work also includes the preparation of pigment compositions based on copper phthalocyanine that are stable to crystallization, particularly suited for coloring printing inks.
