Abstract

It is known in the art to use hydrocarbon polymers and waxes to planarize the rough surfaces of fused solid electrophotographic toners deposited on either paper or transparencies for projection. An optically smooth surface after fusing is important to minimize scattering with color toners to enable vivid colors when projected on a screen or to produce glossy prints on paper. It has been discovered that the choice of materials which can adequately be used to planarize the fused toner extends beyond hydrocarbons and includes all materials with an index of refraction matching that of the toner resin.

Improvement of Image Surface Quality by Planarization with a Second
Index-Matching Medium

      It is known in the art to use hydrocarbon polymers and waxes to
planarize the rough surfaces of fused solid electrophotographic
toners deposited on either paper or transparencies for projection.
An optically smooth surface after fusing is important to minimize
scattering with color toners to enable vivid colors when projected on
a screen or to produce glossy prints on paper.  It has been
discovered that the choice of materials which can adequately be used
to planarize the fused toner extends beyond hydrocarbons and includes
all materials with an index of refraction matching that of the toner
resin.  This includes siloxane polymers, aromatic polymers,
polyesters, polystyrenes, polyvinyl acetates, polyacrylate esters,
polymethacrylate esters, as well as copolymers and mixtures of the
above, or with hydrocarbon polymers, such as polypropylene and
polybutadiene, etc.
