| 摘要 |
The invention provides a process for the production of an image which comprises (i) applying to a substrate a layer of a liquid composition comprising (A) a cationically polymerizable residue (B) a radiation-activated polymerization initator for (A) (C) a radiation-curable residue that is different from (A) and optionally (D) a radiation activated initiator for the cure of (C), (ii) subjecting the composition to actinic radiation having a wavelength at which initiator (B) is activated but at which the residue (C) and/or initiator (D) is not substantially activated, followed by heating, if necessary, so that (A) is polymerized and the layer of liquid composition is solidified, but remains curable, (iii) subjecting the solidified layer in a predetermined pattern to actinic radiation having a wavelength that is different from that of the radiation used in stage (ii) and at which the radiation-curable residue (C) and/or the initiator (D) is activated, such that in the exposed areas (C) is substantially cured, and (iv) removing areas of the solidified layer that have not been substantially cured.
