Title: Manfred Michel: Innovator in Photoconductive Materials

Introduction

Manfred Michel is a notable inventor based in Suzano, Brazil, recognized for his contributions to the field of photoconductive materials. With a total of three patents to his name, he has made significant advancements in the production of printing forms and printed circuits.

Latest Patents

One of his latest patents is a light-sensitive photoconductive recording material. This innovative material consists of an electrically conductive support suitable for creating printing forms or printed circuits. It features a photoconductive layer system that includes a photoconductor, a binder, a sensitizing dye, and conventional additives. The system comprises either a single photoconductive layer or multiple layers applied to the support, along with a light-sensitive covering layer containing at least one photochemically reactive compound. This recording material is particularly useful in processes for producing printing forms and printed circuits.

Another significant patent involves a novel photosensitive recording material designed for the production of planographic printing plates. This material includes a support and a negative-working photosensitive layer that contains a diazonium salt polycondensation product as the photosensitive compound. Additionally, it incorporates a colorless inorganic pigment that is insoluble in water and organic solvents, with an average particle diameter ranging from 1 to 20 micrometers. The pigment is present in a quantity of 0.01 to 2% by weight relative to the non-volatile constituents of the layer, ensuring an even distribution. The inclusion of this pigment results in a rough layer surface, which reduces the time required for creating a vacuum in a vacuum frame and enhances tonal rendering in the final print.
