Abstract
Lithographic printing plate precursors are prepared with a unique aluminum-containing substrate and one or more radiation-sensitive imageable layers. The aluminum-containing substrate is prepared by three separate and sequential anodizing processes to provide an inner aluminum oxide layer having an average dry thickness (Ti) of 500-1,500 nm and a multiplicity of inner pores having an average inner pore diameter (Di) larger than 0 and <15 nm. A formed middle aluminum oxide layer has a dry thickness (Tm) of 60-300 nm and a multiplicity of middle pores of average middle pore diameter (Dm) of 15-60 nm, arranged over the inner aluminum oxide layer. A formed outer aluminum oxide layer comprises a multiplicity of outer pores having an average outer pore diameter (Do) of 5-35 nm and an average dry thickness (To) of 30-150 nm, arranged over the middle aluminum oxide layer. Dm is larger than Do that is larger than Di.
