PURPOSE:To enable the long-term conservation of a raw print and to obtain the clear and sharp printing picture by incorporating the sensitivity-controlling agent bonded with the polymer in the topmost layer of a photosensitive layer. CONSTITUTION:In the photosensitive resin laminated body consisting of at least supporting body, photosensitive layer and cover film, the photosensitive layer consists of at least two layers, and the sensitivity-controlling agent bonded with the polymer is incorporated in the topmost layer. The concrete example of the sensitivity-controlling agent is well-known photopolymerization inhibitor, heat polymerization inhibitor, ultraviolet light absorber or the compd. improving sensitivity balance, and the compd. having the functional group which is neccessary to bond with the polymer, for example, amino, epoxy, isocyanate group is preferable. And when the direct reaction with the polymer is difficult, the bonding agent to bond the active hydrogen of a high-molecular polymer with the sensitivity-controlling agent, for example, a diepoxy compd. and a diisocyanate compd., etc., may further be compounded. |
