A printing blanket including a base fabric and a surface layer in a laminated structure wherein a surface reforming agent containing a perfluoroalkyl group is applied to the surface layer such that a critical surface tension ranging from 10 to 16 dyn/cm appears on the surface of the surface layer is disclosed. To practically manufacture a printing blanket of the foregoing type, there is also disclosed a method wherein a compressible layer is placed on a base fabric, a surface layer is then placed on the compressible layer thereby to form a laminated structure with the base fabric and the compressible layer, and thereafter, a surface modifier containing a perfluoroalkyl group is applied to the surface layer such that a critical surface tension ranging from 10 to 16 dyne/cm appears on the surface of the surface layer. It is preferable that the surface layer is molded of a compound based on a nitrile butadiene rubber. Usually, the surface modifier contains a perfluoroalkyl group of which carbon number remains within the range of 3 to 12.
A printing blanket including a surface layer on a base fabric with a compressible layer placed on said base fabric, wherein a surface modifier containing a perfluoroalkyl group and a functional group having affinity for a rubber constituting said surface layer is applied to said surface layer while exhibiting affinity to the surface of said surface layer such that a critical surface tension ranging from 10 to 16 dyn/cm appears on the surface of said surface layer.
A printing blanket including a surface layer on a base fabric with a compressible layer placed on said base fabric, wherein a surface modifier containing a perfluoroalkyl group and a functional group chemically bondable to a rubber constituting said surface layer is added to said surface layer by allowing said functional group to react on the surface of said surface layer in such a manner that a critical surface tension ranging from 10 to 16 dyn/cm appears on the surface of said surface layer.
A printing blanket including a surface layer on a base fabric with a compressible layer placed on said base fabric, wherein a surface modifier containing a perfluoroalkyl group and a functional group having an affinity for a rubber constituting said surface layer is mixed into said surface layer in such a manner that a critical surface tension ranging from 10 to 16 dym/cm appears on the surface of said surface layer.
A method of manufacturing a printing blanket, wherein a compressible layer is placed on a base fabric, a surface layer is additionally placed on said compressible layer, and thereafter, a surface modifier containing a perfluoroalkyl group and a functional group having affinity for a rubber constituting said surface layer is added to said surface layer, by applying to said surface layer a solution of said surface modifier in a solvent which is capable of penetrating said surface layer while being compatible therewith to effect the obtainment of a critical surface tension ranging from 10 to 16 dyn/cm appears on the surface of said surface layer.
