摘要： Photocurable elements which are useful for preparing flexographic printing plates are provided which comprise a printing layer and a contiguous base layer, the printing layer comprising about 40 to 95 parts by weight of an elastomeric block copolymer, about 5 to 60 parts by weight of a second elastomeric polymer which is incompatible with the block copolymer, a photopolymerizable monomer, and a photoinitiator. The printing layer preferably also comprises an actinic radiation scattering and absorbing pigment.Also provided are relief printing plates prepared from the photocurable elements. The printing plates have a tack-free surface having excellent ink transfer properties, abrasion resistance, and solvent resistance. A high level of exposure latitude may also be provided in the photocurable elements of the invention.

摘要： An expandable, hollow, cylindrical thin-walled composite sleeve for use in flexographic printing applications is provided including an optional polymeric resin base layer, at least one filament wound layer over the base layer, and at least one outer non-woven fibrous layer over the filament wound layer. The filament wound layer may comprise filament wound fibers such as fiberglass which are wound around the base layer or sleeve. The non-woven fibrous layer may be in the form of a fiberglass chopped strand mat. The layers provide desirable surface and reinforcement properties to the sleeve.
摘要翻译：提供了用于柔性版印刷应用的可膨胀的中空的圆柱形薄壁复合套筒，其包括任选的聚合物树脂基底层，在基底层上的至少一个细丝缠绕层，以及至少一个外部无纺纤维层细丝缠绕层。长丝缠绕层可以包括围绕基层或套筒缠绕的细丝缠绕的纤维如玻璃纤维。非织造纤维层可以是玻璃纤维短切纤维垫的形式。这些层为套筒提供期望的表面和增强性能。
