Applying the developing agent as a homogeneous solution in such small amounts would be readily oxidized by the ambient atmosphere.
  • Applicant has previously proposed a fibrous roll for applying monoethanolamine developer liquid in Japanese Patent Application No. 64 930/65 of October 22,
  • This applicator roll is manufactured by blending hygroscopic fiber material such as cotton which has been impregnated with a developer liquid comprising monoethanolamine and gasifying agent such as camphor, with nonhygroscopic fiber material such as synthetic fiber, and with mineral fiber which is capable of allowing gasified developing agent to permeate and diffuse therethrough.

  • .blended fiber material is pressed together to form a roll, which is mounted on a hollow tube which extends centrally and axially therethrough.
  • the central tube contains a heater means and is surrounded by a plurality of hollow tubes which extend axially and are parallel with each other.
  • Each of the surrounding tubes has perforations formed in its peripheral wall for feeding the developer liquid;
  • a copier machine equipped with such a roll application should be provided with a reservoir to which the developer liquid must be occas'sionally added.
  • the roll previously proposed by applicant fails to avoid or to overcome completely the faults referred to above.
  • One object of the instant invention is to provide a roll impregnated with the developer liquid which may be used as an applicator roller in the diazotype copier machine whereby the faults referred to above are completely avoided and overcome.
  • Another object of the invention is to provide a roll capable of holding a considerably greater amount of the developer liquid so that many more copying operations can be made from a single roll without'requiring replenishment of the developer liquid.
  • Another object is to provide a roll capable of exuding the developer liquid impregnated therein in controlled and very small quantities at the peripheral surface of the roll.
  • Still another object is to provide a roll capable of sub-

  • a disk having a central hole is stamped out of the sheet.
  • a plurality of such disks are saturatedly impregnated with the desired liquid.
  • the impregnated disks are then collected and secured together by inserting a shaft into the disk central hole to form a'cylindrical body.
  • the cylindrical body is pressed in the axial direction to allow some of the impregnated' liquid to be squeezed out so that the total amorphous'material, the swelling becomes so great that not onlysaid amorphous material but also saidlow polymerizationmaterial is exuded out.
  • the cellulose fiber mate rial must be of high purity so that a-cellulose content is increased up to.e.g. 98 or 99 percent and alkali soluble contentor alkali solubility is decreased down to e.g.

  • the concerned liquid for example, an aqueous solution of monoethanolamine having the usual additives for developing the twocomponent diazotype material.
  • the amount of the liquid required for saturation impregnation naturally depends on the nature of the liquid, but the amount of the preferred liquid --required is almost-3 times the total weight of the dry disks. In other words the cylindrical body consisting of many disks impregnated with the liquid weighs about four times as much as the total weight of the disks before the impregnation.
  • the entire surface of the roll and immediately following oozing out the liquid is transferred to any other material such as a sheet paper contacted therewith.
  • the roll surface When the roll surface is properly ground or abraded, it is possible to apply the exudated liquid evenly to the material to be treated, but the preferred embodiment is to'cover the roll with a fabric woven or knitted from nonhygroscopic yarn such as synthetic resin fiber or mineral fiber in order to ensure more even liquid application.
