FORMATION OF IMAGE BY PHOTOPOLYMERIZATION

Title:

FORMATION OF IMAGE BY PHOTOPOLYMERIZATION

Document Type and Number:

Japanese Patent JPS5825630

Kind Code:

A

Abstract:

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 bicyclo[2.2.1]hept-2-ene-6-yl unit is exposed to actinic radiation so that the layer solidifies due to photopolymerisation of (A) through the (meth)acryloyl group(s), remaining, however, 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 bicyclo[2.2.1]hept-2-ene-6-yl unit(s) and hence insoluble. An image is produced which can be developed by means of suitable solvents. Examples of (A) include 3-(methacryloyloxy)-2-hydroxypropyl bicyclo[2.2.1]hept-2-ene-6-carboxylate and 2-(acryloyloxy)ethyl methyl-5-carboxybicyclo[2.2.1]hept-2-ene-6-carboxylate.
