PURPOSE:To enhance ink receptivity by incorporating a specified monomer and a specified copolymer in a polymer. CONSTITUTION:The polymer contains (a) a monomer selected from (meth) acrylamides and (meth) acrylates to be added, preferably, in an amount of 1-60 mol %, each having an aromatic hydroxyl group; (b) at least one kind of monomer to be added, preferably, in an amount of 3-30 mol.%, selected from (meth)acrylats and (meth) acrylamides each having an optionally substituted benzyl group; (c) (meth) acrylonitrile; and (d) an alpha, beta-unsaturated carboxylic acid copolymer having an acid value of 10-100, thus permitting the obtained photosensitive composition to be developed with an aqueous solution of alkali, and improved in ink receptivity. |
