(54) Title (EN): POSITIVE WORKING LITHOGRAPHIC PRINTING PLATES
(54) Title (FR): PLAQUES LITHOGRAPHIQUES POSITIVES

(57) Abstract:
(EN): A positive-working lithographic printing plate precursor is disclosed comprising on a grained and anodized aluminum support having a hydrophilic surface or which is provided with a hydrophilic layer, a coating comprising: (i) an infrared absorbing agent and at least one colorant; (ii) a first layer comprising a heat-sensitive oleophilic resin, (iii) and a second layer between said first layer and said hydrophilic support wherein said second layer comprises a polymer comprising at least one monomeric unit that comprises at least one sulfonamide group; characterized in that the surface of said grained and anodized aluminum support has a mean pit depth equal or smaller than 2.2 μm.
(FR): La présente invention concerne un précurseur de plaque lithographique positive comprenant, sur un support d'aluminium granuleux et anodisé ayant une surface hydrophile ou sur lequel est disposée une surface hydrophile, un revêtement contenant : (i) un agent absorbant l'infrarouge et au moins un colorant, (ii) une première couche comprenant une résine oléophile thermosensible et (iii) une seconde couche située entre la première couche et le support hydrophile, cette seconde couche contenant un polymère comprenant au moins une unité monomère constituée d'au moins un groupe sulfonamide. Le précurseur se caractérise en ce que la surface du support d'aluminium granuleux et anodisé a une profondeur de creux moyenne inférieure ou égale à 2,2 μm.
