Lithographic plates with coating

A lithographic plate support comprises a substrate, e.g. of aluminum, and a coating thereon derived from an aqueous composition comprising a sol, e.g. of a hydrous metal oxide such as zirconia, and a polycarboxy organic polymeric material such as polyacrylic acid and the thickness of said coating is...

Beschreibung
Zusammenfassung:	A lithographic plate support comprises a substrate, e.g. of aluminum, and a coating thereon derived from an aqueous composition comprising a sol, e.g. of a hydrous metal oxide such as zirconia, and a polycarboxy organic polymeric material such as polyacrylic acid and the thickness of said coating is at least 30 nm. Such lithographic supports avoid the need for expensive electrograining and anodising or other surface texturing steps, while nevertheless providing excellent print performance.
