Definitions

  • This invention relates to photographic imbibition dye printing processes and materials. lIn one aspect, it relates to improved imbibition dye printing blanks.
  • the imbibition dye printing process is Well known. According to the common procedures, a tanned colloid relief image is ⁇ formed by exposure of a suitable sensitive layer on a support and differentially hardening the colloid layer, thereafter removing the colloid from the support in the regions not exposed by light. The resultant colloid relief image is then dyed and the dye image transferred to a blank by imbibition. In this manner subtractively colored Idye images may be obtained which faithfully reproduce a colored subject.
  • One object of this invention is to provide improved, novel blanks. Another object of this invention is to provide improved, novel imbibition blanks which are treated to prevent matrix poisoning. Still another object of this invention is to provide imbibiton blanks treated to substantially eliminate mordant diffusion. Another object of this invention is to provide novel imbibition blanks which do not stick or slip when pressed against a matrix film. A further object of this invention is to provide imbibition blanks which give good dye density and transfer definition, even after a number of transfers. Still another object of this invention is to provide -a process for preparing such improved imbibition blanks. Another object of this invention is to provide an improved relief imbibition printing process. Other objects of this invention will be apparent from the following disclosure and the appended claims.
  • FIG. 1 is illustrated the manner in which diffusible mordant molecules or particles migrate from an imbibition blank to a matrix film with the adverse effects mentioned.
  • FIG. 2 is shown a similar view of the improved colloid blank of the invention.
  • FIG. 3 is a view similar to FIG. 1 showing the manner in which the blank of FIG. 2 improves the quality of dye transfers and prevents clogging of the matrix and staining of the support.
  • dye imbibition blanks which include a support having a hydrophilic colloid layer thereon containing a basic mordant which tends to diffuse through the colloid, and an effective quantity of a Water soluble acid salt of an alkyl or aryl substituted polyalkoxy ether in the outer stratum of the hydrophilic colloid layer to inhibit or prevent diffusion of the mordant out of said layer. It has been found that the tendency of the mordant to diffuse to the surface, or out of the blank and into a colloid matrix, is effectively prevented with the novel blanks of the invention. At the same time, good dye transfer definition and density are obtained without problems of sticking or slipping.
  • an improvement is provided in the process -for manufacturing mordanted dye imbibition blanks having a hydrophilic colloid layer coated on a support, which features applying to the surface of the hydrophilic colloid layer an acid salt of an alkyl or aryl substituted polyalkoxy ether.
  • an improvement in a relief imbibition printing process that includes transfer of a soluble acid dyestulf from a colloid relief image to ⁇ a colloid blank containing a diffusible, basic mordant and fixing the dyestuff in the blank.
  • This improvement features treating the surface of the blank with an acid salt of an alkyl or aryl substit-uted polyalkoxy ether prior to reacting the dyestuff with the mordant.
  • a wide variety of compounds which are the acid salts of alkyl or aryl su-bstituted polyalkoxy ethers can be employed, such as the alkali metal and ammonium sulfate, sulfonate and carboxylic acid salts of alkyl substituted polyalkoxy ethers. Good results are obtained with such salts which have from l to 100, and preferably l to 5 alkoxy groups, each alkoxy group containing from 2 to 4 car-bon atoms.

  • FIG. 1 shows an enlarged cross-sectional view of the elements concerned, the manner in which ditfusible, perhaps low molecular weight mordant particles, wander out of the colloid layer 11 of gelatin carried on paper support into the dyed relief image 12 and iilm support 13, when dye is being transferred to the colloid blank to be mordanted onto mordant particles 15.
  • this diffusion may clog the relief image, and adsorbed mordant on the support 13 or in a subbing layer thereon results in staining the highlight :region of the print.
  • the blank is conveniently prepared by mordanting the colloid layer with a suitable basic mordant.
  • the mordant is added to a suitable quantity of colloid, such as gelatin with hardener and coated on a support to yield a blank as shown in FIG. 2 wherein a support 10 of paper or film is shown carrying gelatin layer 11 in which basic mordant particles 14 and 15 are dispersed.
  • the blank is bathed for a short time in an aqueous solution of an acid salt of a polyalkoxyalkyl substituted arylether, adjusted to a pH of about 4.0 to 5.0 (e.g., with sodium hydroxide solution).
  • the acid salt may be coated over the colloid surface from such a solution which may in addition contain a vehicle such as gelatin.
  • This treatment of the blank appears to deposit the salt in high concentration as a coating or in an outer stratum of the blank substantially as shown in FIG. 2 according to which support 10 carries the colloid layer 11 containing diffusible and non-ditfusible particles 14 and 15 and a stratum of acid salt particles 16 and some particles 17 which may result from reaction between mordant and acid salt.
  • the acid salts employed in this invention are applied to mordanted blanks from any convenient solution, such as an aqueous solution. Best results are obtained with aqueous solutions adjusted to a pH of 4.0 to 5.0, and using concentrations of about 0.5 to about 1.5 percent acid salt.

  • Examples 1 and 2 demonstrate the superior results achieved when dye imbibition blanks containing diffusible basic mordants are treated with the acidic salts in accordance with the invention.
  • Example 1 A dye imbibition blank was prepared by soaking 454 g. of gelatin in 5360 cc. of distilled water until well swollen, and the mixture then heated to 40 C. to dissolve the gelatin. There Were then added some saponin solution as a coating aid, 65 cc. of 50% aqueous glycerine and 100 g. of a solution of the resinous mordant produced according to Example 1 of Minsk U.S. Patent 2,882,156 (issued Apr. 14, 1959), in dilute acetic acid. 'Ihe pH of the mixture was adjusted to approximately 4.2 and 27 cc. of 10% formaldehyde solution was added.
  • the resulting solution was coated onto a cellulose acetate film support at the rate of approximately 1.25 g. of gelatin (dry weight) per square foot.
  • the blank thus obtained was prewet for one minute in distilled water, and the excess Water was blown off by means of an air squeegee.
  • the blank was then dipped for approximately 3 seconds in a solution of 1.0 percent (active agent) Stepanol B-129 (believed to be a 50 percent solution of nonylphenoxypolyethylene oxide sulfonate, sodium salt, manufactured by Stepan Chemical Co.) plus 0.5 percent citric acid, with the pH of the solution adjusted to 4.2 with sodium hydroxide.
  • a series of six trensfers were made to these blanks using a gelatin relief matrix containing an acid yellow dye stuff (e.g., Anthracene Yellow GR, Schultz No. 177).
  • the yellow dye stain in the minimum density areas of the matrix after the six transfers was only 0.03, measured through an appropriate blue filter. There was no loss of dye transfer density and the definition was better than transfers made with a control.
  • the same imbibition blank was employed but the process was altered by omitting treatment with the aqueous acid salt solution.
  • the yellow dye stain in minimum density areas of the matrix of the control was 0.15 measured through the same blue filter.
  • Example 2 fers, the matrix showed a stain 0.18 in minimum density r areas.
  • Example 3 The procedure of Example 1 was followed except that after the blank was prewet with water, it was dipped for approximately 3 seconds in a 1 percent solution of sodium laurylpolyethoxy sulfate (Sipon ES, Alcolac Chemical Corp.) at a pH of 4.2. The matrix stain after Isix transfers was only 0.02.
  • Example 4 The procedure of Example 1 was followed except that after the blank was prewet with water, it was dipped for approximately 3 seconds in a 1 percent solution of sodium polyacrylate at a pH of 4.2. The matrix stain after six transfers was reduced to only 0.09 density. Higher concentrations of sodium polyacrylate were viscous and slippery and caused trouble in transfer operations, such as bad sticking between matrices and blanks.
  • Example 5 The procedure of Example 4 was followed except that the blank was dipped, after being prewet with water, in a 1 percent solution (pH 4.2) of low viscosity carboxymethyl cellulose. Matrix stain after six transfers of yellow dye was 0.04 density. However, the images obtained had a much lower transfer definition than those obtained in accordance with Example 1.
  • Example 6 The procedure of Example 5 was followed except that the blank was dipped, after being prewet with water, in a one percent solution of a sulfonated polystyrene (Lustrex 770). After six transfers, the matrix stain was 0.03, lbut there was an undesirablelowering of transfer density with each successive transfer.
