Filed: 1999-07-16
Abstract: PROBLEM TO BE SOLVED: To obtain nickel oxide of a low sulfur content in which the average grain size is controlled by subjecting nickel sulfate containing a small amount of alkali metals and alkaline-earth metals to 1st roasting at a specified temp. in an oxidizing atmosphere and thereafter executing 2nd roasting at a specified high temp. SOLUTION: Nickel sulfate is subjected to double roasting in an oxidizing atmosphere by using kiln or the like. As the raw material nickel sulfate, the one in which the content of alkali metals and alkaline-earth metals as impurities suppressing its decomposition is about <=100 wt.ppm is desirable. Furthermore, the 1st roasting is executed at the roasting temp. of 950 to <1000 deg.C, preferably of 970 to 990 deg.C for the roasting time of 15 to 60 min. In this way, nickel sulfate causes decomposing reaction, and, at a sufficient sintering rate, nickel oxide powder of about <=0.5 μm average grain size is obtd. Moreover, the 2nd roasting is executed at the roasting temp. of 1000 to 1200 deg.C for the roasting time of 30 to 120 min.  In this way, the sintering is executed at a sufficient rate, by which the average grain size of nickel oxide increases, and furthermore, the concn. of sulfur reduces to about <=50 wt.

Title: Photosensitive planographic original printing plate and production of planographic printing plate
Inventor: ISONO MASANAO
IPC: G03F7/033
Filed: 1995-08-10
Abstract: PROBLEM TO BE SOLVED: To form an image without a complicated developing process and to produce a planographic printing plate at a low cost by incorporating a photo- acid initiation into a photosensitive hydrophilic swelling layer of a photosensitive planographic original printing plate. SOLUTION: This photosensitive planographic original printing plate has a photosensitive hydrophilic swelling layer on a substrate, and the hydrophilic swelling layer contains a photo-acid initiation. As for the photo-acid initiator, a diazo compd., polyhalogen compd. and onium salt compd. can be used. The photo-acid initiator produces Lewis acid or Bronsted acid by exposure, and the produced Lewis acid or Bronsted acid changes the hydrophilic carboxyl groups included in the hydrophilic swelling layer into hydrophobic free acid to decrease the hydrophilicity of the whole layer. The exposed part of the hydrophilic swelling layer is changed into hydrophobic by exposure, which increases the initial elastic modulus and decreases the swelling property with water to form a printing area having ink-depositing property. The unexposed part forms a non-printing area having ink-repellency.
