A negative imageable element is prepared with a radiation sensitive imageable layer comprising surface modified silica particles, such as fumed silica particles and sol-gel silica particles, wherein the silica particles are present in an amount of about 1 to about 40 weight percent. From about 0.5 to about 15% by weight derived from surface hydrophobic groups having an average particle size of from about 1 to about 500 nm, having surface hydroxy groups, and having from 1 to 30 carbon atoms Has a carbon content of The presence of surface modified silica particles provides improved wear resistance, reduced tack, and various other desirable properties. |
