Patent ID: 7183041

Claim:
A process for obtaining a printing plate comprising at least a photopolymer layer ( 3 ) having two faces and a first layer ( 4 ) of a given material and constituting a support layer of said photopolymer layer and having two faces, said method comprising the steps of applying on one face of the support layer ( 4 ) a layer of pressure sensitive bonding material ( 40 ), rolling up said support layer ( 4 ) on said photopolymer layer to form a roll with said photopolymer layer ( 3 ) on said support layer ( 4 ), while causing said photopolymer layer ( 3 ) to come by one of its faces in contact with the face of the support layer ( 4 ), provided with said layer of pressure sensitive bonding material ( 40 ) at the beginning of the rolling up said rolling up of said polymer layer ( 3 ) and said support layer ( 4 ) generating a radial pressure between said layers in the roll, using said radial pressure to cause said pressure sensitive bonding material ( 40 ) to fix the photopolymer layer ( 3 ) to the support layer ( 4 ), whereas the face of the support layer ( 4 ), which is opposite the face provided with said pressure sensitive bonding material layer comes in contact with the face of the photopolymer layer opposite the face fixed to the support layer, the support layer ( 4 ) constituting thus a protective layer of the photopolymer layer.
