Abstract
This invention relates to a process for preparing a photosensitive composition having a low heat history which includes: (a) forming a substantially homogeneous dispersion by mixing at least one photoinitiator or photoinitiating system, and at least one binder selected from the group consisting of reactive binders and non-reactive binders in the form of a dispersion provided that when said binder is non-reactive then at least one reactive component is added which is capable of reacting with the photoinitiator; (b) coagulating the dispersion to form a coagulum and a liquid; and (c) substantially removing the liquid to form a photosensitive composition.
