ABSTRACT:
A photosensitive elastomeric composition comprising (1) at least one elastomer, (2) an addition-polymerizable compound having at least one CH.sub.2 .dbd.C< group and (3) a polymerization initiator activatable by actinic light, wherein the elastomer (1) is an elastomer selected from (a) an elastomeric polymer composed of a polyene monomer containing at least two non-conjugated double bonds and a conjugated diene-type monomer or both a conjugated diene-type monomer and a copolymerizable vinyl monomer and (b) an elastomeric linear A-B type (wherein A represents a polymer block of a monovinyl aromatic compound and B represents a polymer block of a conjugated diene-type monomer) block copolymer in which a terminal group having a polymerizable ethylenic double bond is present in at least one end of the molecular chain.
