ABSTRACT:
Photoactive, thermally coalescible resin plastisol dispersions comprising a polyvinyl chloride polymer having attached to the polymer backbone photopolymerizable or photocrosslinkable groups dispersed in a liquid plasticizer medium, and a photoinitiator which is either a separate component or a photoactive substituent present on the polymer backbone. The photoactive plastisols, in element form, can be used in an image formation process that is a positive working washout or negative toned imaging system.
