The invention provides a photosensitive resin composition containing a soluble synthetic linear high-molecular compound in an amount of 25 to 95 weight percent based on the whole composition, a monomer having at least one photopolymerizable unsaturated bond and a photopolymerization initiator and characterized in that part or all of the soluble synthetic linear high-molecular compound is an addition polymer of an organic diisocyanate compound with an amide compound, both terminals of the amide compound being either primary or secondary amide groups and the equivalent ratio of amino groups to isocyanate groups in the addition polymer is not less than 1.0. The high-molecular weight compound makes up at least 50% by weight base on the total amount of the polymer material present in the composition.

Photosensitive resin composition

An image reproducing material comprising a supporting sheet bearing a metal or metallic compound layer having a thickness of 100 to 1000 .ANG. and a photosensitive resin layer, which is characterized in that said photosensitive resin layer contains (1) an ethylenically unsaturated compound which is polymerizable by the action of free radical and chain propagative, (2) a compound showing photochromism by radical mechanism, (3) a free radical producing agent and (4) an acitinic light absorber. There is also provided an image formed (reproduced) material obtained by patterned exposing the above image reproducing material and then processing the same, a method for obtaining such image formed material and also a method for dot-etching such image formed material. By the use of these materials and methods, dot-etching can be effected easily and there are obtained sharp images without the formation of pin holes.
