Abstract
A record carrier for an electro-erosion printer having an outer metal layer surface with roughness of high frequency, low amplitude and a soft, rounded-off waviness practically without edges or steps.
Claims9
A record carrier for an electro-erosion printer, said carrier coprising a base material coated with a lacquer layer containing a pigment, said lacquer layer being covered in turn by a thin metal layer comprising, aluminum, characterized in that the roughness of the metal layer surface caused by the pigment contained in the lacquer layer (2,6) has a high frequency, a low amplitude, and a soft, rounded-off waviness practically without edges or steps.
A method for making a record carrier covered by a lacquer of high dullness resistant to abrasion and scratching traces, characterized in that a first polymeric lacquer layer highly filled with pigment is deposited on the carrier material, said layer containing only soft pigment with a grain size of more than 5 .mu.m, and that another polymeric lacquer layer is applied thereon which contains either only fine, soft pigment with a grain size of less than 1 .mu.m to approximately 2 .mu.m, or a soluble dye.
