    摘要: In a three stage process, a layer of a liquid composition containing a compound (A) having in the same molecule at least one (meth)acryloyl group and at least one 2,3-disubstituted maleimido group is exposed to actinic radiation so that the layer solidifies due to photopolymerization of (A) through the (meth)acryloyl group(s), remaining, however, further photocrosslinkable. When desired, the solidified layer is exposed, as through a negative, to a substantially greater amount of actinic radiation, the parts so further exposed becoming more highly photocrosslinked through the disubstituted maleimido group(s) and hence insoluble. An image is produced which can be developed by means of suitable solvents. Examples of (A) include N-(2-(acryloyloxy)ethyl)-2,3-dimethylmaleimide and N-(3-(methacryloyloxy)-2-hydroxypropyl)-2,3-dimethylmaleimide.
