Definitions

  • This invention relates to diazotype reproduction mat rials and to methods for their preparation and use, and refers more particularly to heat-developable two-compo nent photosensitive diazotype reproduction materials and methods for their preparation and use.
  • Diazotype reproduction materials are Widely used commercially because of their combined advantages of quality and low cost.
  • Two types are generally used: the semiwet developing type and the dry developing type.
  • Each has its own inherent disadvantage.
  • the handling of a liquid developer is a negative factor.
  • the dry developing type the machine requirements for confining and exhausting noxious ammonia fumes are negative factors.
  • the loading of concentrated ammonia water and the removal of spent ammonia water from the machine are disagreeable tasks in the daily use of dry developing machines.
  • Thermographic reproduction processes have been used to avoid or eliminate some of the disadvantages of the diazotype processes, but they possess other objectionable properties such as the retention of sensitivity to heat even after the desired reproduction has been made. In addition these materials are not necessarily photosensitive.
  • the present invention combines the advantages of the diazotype process with that of the thermographic process While avoiding some of the disadvantages of both.
  • the quality and low-cost of the diazotype process is combined with the simplicity of development of the thermographic process.
  • the use of liquid developers and gaseous ammonia is avoided, and the final reproduction is insensitivejo further application of heat.
  • one object is to provide a heat-developable photosensitive diazotype reproduction material which does not have the disadvantages of the prior art.
  • Another object of the present invention is to provide a heat-developable two-component photosensitive diazotype reproduction material.
  • Another object is to provide a diazotype reproduction material which is developable without the use of liquid developers or gaseous ammonia.
  • Another object is to provide a heat-developable reproduction material which, after development is stable to further undesirable development due to the application of heat.
  • Another object is to provide a method for the preparation of heat-developable two-component photosensitive diazotype reproduction material.
  • Another object is to provide a method for the use of heat-developable two-component photosensitive diazotype reproduction material.
  • Another object is to provide a developing sheet for the heat-development of a two-component photosensitive diazotype reproduction material.
  • Another object is to provide a method for the use of a developing sheet in the heat-development of a two-component photosensitive diazotype reproduction material.
  • Another object of the present invention is to provide a reproduction material which has good quality and low cost.
  • FIGURE 1 is a sectional view of a heat-developable ice two-component photosensitive diazotype reproduction material 16 comprising a support 11 and a heat-developable two-component photosensitive diazotype layerlZ coated on said support.
  • FIGURE 2 is a sectional view of a heat-developable two-component photosensitive diazotype reproduction material 29 comprising a support 21, a precoat layer 22 coated on said support, and a two component photosensitive diazotype layer 23 coated over said precoat layer on said support.
  • FIGURE 3 is a sectional view of a developing sheet 36 comprising a support 31 and a base-releasing agent 32 impregnated in said support in contact With a two-component photosensitive diazotype reproduction material 40 comprising a support 41 and a two-component photosensitive diazotype layer 42 coated on said support.
  • thermosensitive base-releasing agents of the present invention is a group of chemical structural formulas of the thermosensitive base-releasing agents of the present invention:
  • the base-releasing agent can be incorporated into the sensitized layer, into a separate precoat layer between the support and the sensitized layer, or it can be impregnated into a separate support to make a developing sheet. Compatibility with the other chemicals in the sensitizing solution determines Whether or not it can be incorporated into the various systems. Generally where it is incorporated with the sensi izing solution adjustments are required to prevent precoupling of the diazonium compound and the coupler. Base is released under the influence of heat.
  • the agent can either be coated on the same support in a precoat layer between the support and the sensitizing layer or it can ,be coated or impregnated into a separate support to form a developing sheet.
  • the base-releasing agents found to be suitable for the present invention are organic nitrogen compounds such 'as hexamethylenetetramine, thiosemicarbazide, and combinations of these with other organic nitrogen com,- pounds. Combinations of hexamethylenetetramine with semicarbazide hydrochloride for example were found to be satisfactory for purposes of the present invention.
  • thermosensitive diazotype reproduction materials with the base releasing agent in either the sensitizing layer or a precoat layer is the same. Both are exposed conventionally through a master to actinic radiations to form latent images in the reproduction material. the master, both can be heated in the temperature range between the heat activation temperature of the thermosensitive base-releasing agent and the scorchingtemperature of the reproduction material support. Temperatures of about 140 to 160 C. have been found to be adequate for development purposes.
  • the developing sheet In the case of a developing sheet, the developing sheet is placed in face-to-face contact with van exposed twocomponent photosensitive diazotype reproduction material and. the assembly heated preferably from the developing sheet side. The heat releases the base from the base-releasing agent and the base migrates to the exposed diazotype reproduction material and thus permits coupling to take place. Reproduction of the original image is thus effected.
  • Example 1 A support was coated with a sensitizing solution prepared according. to the following formula:
  • the sensitized support was exposed to actinic radiations through a master and then heated at 160 C. for a few seconds. A red-violet image corresponding to the master image was produced on a yellow background.
  • Example 2 Hexamethylenetetramine was used in the following formula to make a precoat solution:
  • Example 1 After removal of This was coated on a support and dried.
  • Example 3 Hexamethylenetetramine was used in the following solution to prepare a developing sheet:
  • Example 5 V A 'precoat solution was prepared according to the following formula:
  • a stock solution was prepared according to the following formula:
  • a sheet for the thermal development of a photosensitive diazo layer comprising a photosensitive diazonium compound and a coupler therefor, which comprises:
  • thermosensitive base-releasing agent selected from the group consisting of: hexamethylene tetramine, thiosemicarbazide, and mixtures of hexamethylene tetramine with one of the following: semicarbazide hydrochloride, carboxymethyl trimethyl ammonium chloride hydrazide, carbohydrazide, succinhydrazide, and acetone semicarbazone coated on said support,
  • a sheet for the thermal development of a photosensitive diazo layer comprising a photosensitive diazonium compound and a coupler therefor, which comprises:
  • a sheet for the thermal development of a photosensitive diazo layer comprising a photosensitive diazonium compound and a coupler therefor, which comprises:
  • thermosensitive base-releasing hexamethylene tetramine coated on said support between said support and said diazo layer thermosensitive base-releasing hexamethylene tetramine coated on said support between said support and said diazo layer.
  • a method for thermally developing a photosensitive diazo layer comprising a photosensitive diazonium compound and a coupler therefor, which comprises the steps of:
  • thermosensitive base-releasing agent a member selected from the group consisting of: hexamethylene tetramine, thiosemicarbazide, and mixtures of hexamethylene tetramine with one of the following: sernicarbazide hydrochloride, carboxymethyl trimethyl ammonium chloride hydrazine, carbohydrazide, succinhyclrazide, and acetone semicarbazone.
