In a manifold imaging process where a thermo~-solvent is
employed to activate the imaging layer, images of high
quality and increased density are obtained by cooling the
imaging layer prior to separation of the manifold imaging
set,

The first step in the thermo~solventmanifold imaging process
is to activate the thermo-solvent, The manifold member
comprising insulating donor layer 13, imaging layer 20,
receiver layer 15 and thermo~-solventactivator layer 16 is
passed between heated rollers 17 and 19 which cause layer 16
to melt.

The activator serves to swell or otherwise weaken imaging
layer 2O~ Typical imaging layers comprise metal~free
phthalocyanine particles dispersed in an insulating binder.
Thermo-~solvents are typically polymers which liquify at
elevated temperatures to become a solvent for the insula~
ting binder of the imaging layer.

Once the desired physical properties have been imparted to
imaging layer 20, the manifold set proceeds through electrodes
21 and 23 which are connected to potential source 25 through
resistor 27,

IMPROVED MANIFOLD IMAGING PROCESS (Cont~d)

After receiving an electrostatic charge on each surface, the
imaging member is advanced to the imaging station where it
is exposed to light image 31.

The manifold set is then moved past...
