ABSTRACT:
A process for producing a novel photosensitive resin having cinnamic groups, comprising reacting a polyallylamine represented by the general formula (I) ##STR1## (wherein n is at least 10) or an inorganic acid salt thereof with a compound having a cinnamic group in the presence of a solvent. The process is free from drawbacks as experienced in the production of a conventional photosensitive resin (e.g. polyvinyl cinnamate), such as formation of by-products during the polymerization of a monomer (e.g. vinyl cinnamate).
