摘要： A negative working light-sensitive composition and a lithographic printing plate using the composition are described. The printing plate is comprised of a hydrophilic support and a thin layer of a negative working light-sensitive composition on the support. The light-sensitive composition contains a light-sensitive diazo compound and a compound capable of increasing absorption over the light-sensitive wavelength region of the composition with increasing exposure time.

摘要： PURPOSE:To obtain a magnetic recording medium which improves a C/N characteristic and is suitable for high-density vertical magnetic recording by using fine hexagonal ferrite powder having a specific plate diameter and specifying the volume ratio of the ferromagnetic material in a magnetic layer. CONSTITUTION:More particularly preferable hexagonal ferrite powder as a ferromagnetic material includes the respective Co substitutes of barium ferrite and strontium ferrite. The ferromagnetic material of this invention has 0.015-0.07mum, more particularly preferably 0.02-0.06mum plate diameter. If the plate diameter is larger than 0.07mum, the output increases but noise increases more, resulting relatively in a decreased C/N. The noise decreases with the plate diameter below 0.015mum but the output decreases and the ferromagnetism necessary for magnetic recording is no longer obtd. The output is low and the C/N is correspondingly low if the volume ratio of the ferromagnetic material is below 0.2. The volume ratio of the non-magnetic material is preferably >=0.20, more preferably >=0.25.

摘要： PURPOSE:To obtain the magnetic recording medium improved in overall performance by incorporating a vinyl chloride resin, phenoxy resin, etc., as a binder into a magnetic layer and incorporating one kind selected from polyalkylene oxide alkyl phosphate and others and lecithin as a lubricating agent therein. CONSTITUTION:The magnetic recording medium is constituted by providing the magnetic layer dispersed with the binder in fine ferromagnetic powder on a nonmagnetic base and is improved in stability with age, still durability, etc. Namely, the vinyl chloride resin, phenoxy resin, polycarbonate polyurethane resin, and polyisocyanate resin are incorporated as the binder into the magnetic layer and at least one kind selected from the polyalkylene oxide alkyl phosphate, the alkaline salt of the polyalkylene oxide alkyl phosphate and the lecithin is incorporated as the lubricating agent therein. The still durability is improved and the stability with age is improved by combining these components and as a result, the output is greatly improved.

摘要： PURPOSE: To prevent thickening of image lines without lowering sensitivity, by adding to a negative type photosensitive compsn. a compd. increasing in accordance with the progress of exposure, absorption of light of wavelength near the wavelength region of the light to which said compsn. is sensitive.
CONSTITUTION: The present negative type photosensitive lithographic plate is obtained by mixing (A) a photosensitive diazo compd., such as 2-methoxy-4-hydroxy-5-benzoylbenzenesulfonate resulting from condensation of p-diazodiphenyl- amine with formaldehyde, (B) a polymer, such as 2-hydroxyethyl methacrylate copolymer, and (C) a compd. increasing absorption of light of wavelength near the wavelength region of the light to which the component A is sensitive, as exposure proceeds; and forming a thin film of said mixture, i.e. the negative type lithographic compsn. on a hydrophilic support. The component C is exemplified by a dye represented by the formula shown in which R is -COOC
2 H
5 , or -CH
3 , and Q is H or phenyl.

摘要： PURPOSE:To obtain a surface protective agent for eliminating stains at non-image portion by diffusing alkali soluble resin into the aqueous solution of water soluble high molecular compound, thereby increasing the fat unsensitivity at the non-image portion without decreasing the fat sensitivity at the image portion. CONSTITUTION:Preferably 0.1-20 wt% of an alkali soluble resin such as phenol formaldehyde resin and polyhydroxystyrene is diffused into the aqueous solution of a water soluble high molecular compound such as a water soluble cellulose ether. If desired, for example, 0.1-0.5 wt% of moistening agent such as polyhydric alcohol may be further added. It is preferable that the above-stated water soluble high molecular compound should be of 10-20 wt%.
