摘要： A liquid etchant and a method for roughening a copper surface each capable of providing copper with a roughened surface increased in acid resistance regardless of a chlorine ion in a short period of time, to thereby ensure firm adhesion between a copper conductive pattern and an outer layer material during manufacturing of a printed circuit board, resulting in the manufacturing being highly simplified. The liquid etchant includes a main component containing an oxo acid such as sulfuric acid and a peroxide such as hydrogen peroxide. Also, the liquid etchant includes an auxiliary component containing a tetrazole such as 5-aminotetrazole or the like, or a 1,2,3-azole. The liquid etchant permits a copper surface to be roughened in an acicular manner.

摘要： A support made of an aluminum plate for a planographic printing plate is electrochemically roughened in an acidic aqueous solution in an electrolytic apparatus with plural cathodes and anodes arranged alternately on one side of the plate by applying a DC voltage. A soft starting zone which comprises at least one electrode connected to an electric power supply, which is separate from a main electric source, is provided. A current density of 0.01 to 100 A/dm2, which is lower than the current density used in any subsequent main roughening, is provided in the soft starting zone.

摘要： A substrate for a planographic printing plate and a method of fabrication thereof. After a surface roughening treatment and before an anodizing treatment, an aluminum alloy plate to be used as the substrate is washed in an alkali solution, and then in an acidic solution. After surface-roughening, overlap points of Fe and Si macularly distributed at the surface of the aluminum alloy plate have a surface coverage of not more than 0.5%, and there are no more than 800 per 1 mm2 of overlap points which have sizes larger than 1.6null10null7 mm2.
