ABSTRACT:
Presented is a reusable printing form including a printing area that has a metal oxide surface, in particular a native oxidized titanium surface, which is treated with at least one amphiphilic organic compound whose polar region has an acidic character. In an advantageous embodiment, n-heptadecanyl hydroxamic acid {CH3-(CH2)16-C(O)—NH—OH} and/or n-octadecanyl phosphonic acid {CH3-(CH2)17-P(O)—(OH)2} is used. Also described is a method for imaging a reusable printing form. The reusable printing form can be used for offset printing.
