摘要:
The present invention provides a photosensitive recording material having a support, and a photosensitive layer and a protective layer formed in this order on or above the support. The photosensitive layer contains a polymerization initiator, a sensitizing agent, and a polymerizable compound. Further, the protective layer contains a water-insoluble and alkali-soluble dye that has an absorption wavelength region different from the absorption wavelength region of the sensitizing agent, and the dye is dispersed in a solid state in the protective layer. The present invention also provides a planographic printing plate precursor including the photosensitive recording material, a stack of the photosensitive recording materials, and a stack of the planographic printing plate precursors.

The present invention provides an automotive inner ceiling material difficult to deform at a high temperature. Sheath-core type conjugate polyester fibers are prepared. The sheath is a heat fusible component. The core is a non heat fusible component. The sheath is made of copolyester which comprises acid units made of terephthalic acid and diol unites made of ethylene glycol and 1,4-butanediol. The conjugate fibers and the main fibers of polyester are mixed and provided in a card machine to be opened and accumulated to obtain a fibrous web. The fibrous web is heated to melt the sheaths, which are thereafter solidified to bind the fibers to obtain a non woven fabric. The nonwoven fabric is heat-treated at a temperature equal to or higher than the melting point of the sheath. Immediately thereafter, the nonwoven fabric is heat-molded between a pair of a mold plates. During the heat-molding process, the inner temperature is maintained at 100˜130° C. for 60 seconds to obtain the ceiling material.

The invention provides a planographic printing plate precursor that is writable by laser exposure and is composed of a support, a photosensitive recording layer formed on the support, and a backcoat layer containing an epoxy resin, the backcoat layer being formed on the side of the support opposite to the photosensitive recording layer side; and a stack of the planographic printing plate precursors. According to the invention, scratches on the photosensitive recording side of the planographic printing plate precursor can be prevented when brought into contact with another planographic printing plate precursor in the stack without interleaving slip sheets, and productivity in a plate making process can be improved.

摘要:
The production efficiency of silicon single crystal produced by additional charge or recharge method is improved by avoiding loss due to undissolved portion of poly-silicon rod supplied in the additional charge or recharge. A poly-silicon rod 20 as an additional charge is brought down in a silicon melt 11 in a crucible 10, while being directly supported by a seed crystal 40. The poly-silicon rod 20 is brought down to be totally supplied to the silicon melt 11, and then silicon single crystal 44 is pulled using the seed crystal 40.
