Title: Leslie Ainsley Simpson: Innovator in Paint Technology

Introduction

Leslie Ainsley Simpson is a prominent inventor based in Normanby, GB. She has made significant contributions to the field of paint technology, holding a total of 5 patents. Her innovative work focuses on the development of advanced emulsion paints and composite materials.

Latest Patents

One of her latest patents involves a gloss emulsion paint that comprises a dispersion of structured composite particles. These particles consist of an association of inorganic pigment and polymeric particles. The polymeric particles are formed from a polymer or copolymer with a minimum film-forming temperature not exceeding 50 degrees Celsius. The structured particles are held together by surface charges, with the polymeric particles having an opposite charge to that of the inorganic pigment particles. The ratio of polymeric particles to inorganic pigment in the composite ranges from 0.5:1 to 6:1 by volume.

Another notable patent is for a structured composite pigmentary material that includes composite particles made up of titanium dioxide and non-film-forming organic polymer particles. The particles are held together due to the positive surface charge on the titanium dioxide and the negative surface charge on the polymeric particles. The volume ratio of polymeric particles to titanium dioxide particles is maintained between 0.3:1 and 0.6:1. This patent also describes an aqueous paint composition and a method for preparing the structured composite pigmentary material.
