<P>PROBLEM TO BE SOLVED: To provide a lithographic printing plate which is improved in bonding strength with a support and transfer silver images, and provided with superior high printing resistance, in an aluminum lithographic printing plate using an aluminum plate as a support and utilizing a silver complex salt diffusion transfer method. <P>SOLUTION: A physical development nuclei layer is formed by a thermal spraying method on a roughened and anodized aluminum support. As a suitable thermal spraying system, they are flame spraying that uses gas flame such as oxygen or acetylene mixed gas as a heat source of thermal spraying, a high-speed flame spraying that uses hyperbaric oxygen and hydrocarbon fuel gas, and a plasma spraying that uses high temperature and high-speed plasma generated as a heat source by making inert gases such as argon, neon, helium, krypton, or xenon gas flow between electrodes to be discharged and ionized, and the like. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
