Positive and negative working imaging systems from photoactive plastisols

摘要

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 the element form, can be used in an image formation process that is positive working washout or negative toned imaging system.
