A dry photosensitive lithographic printing plate has a base, a photosensitive layer formed on the base and a silicone rubber layer formed on the photosensitive layer. The silicone rubber layer is formed from a silicon rubber composition containing an organopolysiloxane and a reactive aromatic aminosilane compound.

A contact lens comprising a lens substrate in shape of a lens which comprises a triorganovinylsilane based polymer, said lens substrate having a hydrophilic polymeric chain grafted onto the surface thereof. This contact lens is not only excellent in oxygen permeability, mechanical strength, dimensional stability, vision correcting ability, staining resistance and handleability, but also good in affinity with eyes due to good hydrophilic property possessed by the surface, which can be worn continuously for a long time.

A presensitized plate for use in making a planographic printing plate requiring no dampening water which comprises a support having provided thereon, in order, a light-sensitive layer comprising a photodimerizable resin and a silicone rubber layer comprising an organopolysiloxane cured with a crosslinking agent comprising a reactive silane compound having a carbon-carbon double bond to which a silicon atom is not directly linked. The presensitized plate shows excellent developing properties and fine dot reproduction.
