Definitions

  • the principal object of this invention is to improve the wettability of a photographic base material, such as polyethylene film or polyethylene laminated paper, by undercoating solutions and light-sensitive emulsions.
  • British Pat. No. 971,058 discloses that the contact angle of water to the polyethylene surface is reduced by electron radiation.
  • the reductionof the contact angle which can be obtained by this vmethod is limited and it is very difficult to reduce the contact angle to less than 50.
  • cmooo x (I) in which R is a hydrocarbon group, preferably an alkyl group of eight to 22 carbon atoms, R is hydrogen or a lower alkyl group, M is an organic amino group or a metal, p and q are integers, preferably from one to five, x is preferably from one to three, y is preferably one, or, when M is a metal, x and y are numbers determined by its valence, followed by the preparation of a base material having a surface comprising this mixture, such as a film or laminated paper, and subjecting such surface to a corona discharge treatment.
  • alkyl amino groups such as diethylamino and butylamino
  • alkanolamino groups such as diethanolamino and propanolamino and the like.
  • metals represented by R in the above formula there may be mentioned such metals as calcium, magnesium, aluminum, tin, zinc, iron, copper, lead, barium and the like.
  • the above mentioned material (I) has the effect of improving the wettability of polyethylene, the addition of larger amounts of such compounds to polyethylene tends to result in a deterioration of the adhesiveness of the polyethylene to light-sensitive emulsion or undercoating layers. Therefore, the amount thereof to be added is limited.
  • Material in accordance with the foregoing structural formula (I) can be synthesized by reacting a higher alkylamine with ethylene oxide of propylene oxide, reacting the product with monochloroacetic acid or its sodium salt and subjecting the resulting reaction product to neutralization with an organic amine, or to double decomposition, to thus obtain the corresponding salt.
  • the following reaction schema illustrates this process.
  • any of these compounds may be blended in polyethylene in accordance with this invention.
  • a very small amount of these compounds is sufficient to achieve the object of the invention.
  • Preferred amounts to be incorporated are 0.3 to 0.5% by weight based on the weight of the polyethylene.
  • a polyethylene laminated paper it has been found that the addition of more than l% by weight results in gradual deterioration in the adhesiveness between the polyethylene and the paper, although wetting by an emulsion or undercoating agent coated thereon is improved.
  • the advantages of this invention can be realized, however, even at proportions exceeding 1%, to some extent. Moreover, the lower limit may be extended, for example, to about 0.1%.
  • Addition of the compound may, as occasion demands, be carried out after it is dispersed or dissolved in a high boiling organic solvent.
  • the compound, after being added to the polyethylene, is kneaded therewith in an extruder such as those used in film making or film applying.
  • the photographic base material of the present invention is a base material, the surface of which, at least, comprises polyethylene containing the foregoing compound.
  • polyethylene containing the foregoing compound examples may be mentioned polyethylene film and polyethylene-coated paper, cloth, wood and metal.
  • this base material is subjected to a corona discharge, whereby the wettability of the polyethylene surface by light-sensitive emulsions and aqueous undercoating solutions is improved.
  • EXAMPLE 1 0.3 Part by weight of material A, represented by the formula was mixed with 100 parts of polyethylene resin pellets manufactured by Nippon Unicar Co., Ltd. (NUC-8008, having a density [ASTM-D-l505-60T] of 0.918 and amelt index [ASTM D-l23857T] of 5.0) and extruded and applied at LII 30C. to a raw base paper of 180 g/m so as to provide a film thickness of about 30 microns, by the use of a T-die extruder.
  • a laminated paper was prepared using the polyethylene free from material A. The contact angle with water was measured for both the samples, before and after being subjected to corona discharge treatment.
  • the corona discharge treatment was carried out at a discharge power of 35 W, 70 W and 180 W by means of a discharge apparatus made by Lepel Highfrequency Laboratories, Inc. while moving polyethylene laminated paper of 30 cm in width at a rate of 10 m/min through an air gap of 0.8 mm.
  • EXAMPLE 2 (CHzCHzOhlI CHILD-N (G1I2ClIzO)21I O [I GU20 O O 3 were mixed, respectively, with parts of high density polyethylene resin pellets manufactured by Showa Denko Co., Ltd. (Sholex 6050, having a density [ASTM-Dl505-6OT] 0.960 and a melt index [ASTM-D-l238-57T] of 5.0) and then formed into films of about 0.1 mm in thickness by the use of a T-die type extruder of 65 mm. Similarly, a material B- free film was prepared for comparison.
  • the contact angle was measured for the resulting samples, before and after being subjected to discharge treatment at W by the same apparatus as that of Example 1, to obtain the results tabulated below.
  • Sample No discharge Discharge treatment treatment No materialB l5g/1O mm 53 g/lO mm 0.15 part of material B (to 100 parts of polyethylene) 14 66 0.3 part of material B (to 100 parts of polyethylene) 5 l no adhesion
  • the photographic light-sensitive emulsion employed above was prepared from a mixture of 70 g of gelatin,-62 g of a silver halide (65 mol.% AgCl, 35 mol %'AgBr) having an average particle size of 0.1 micron and sufficient water to make 1000 cc.
  • the method of preparing the emulsion was conventional and included sensitization with sulphur and a gold salt and the incorporation of saponin as a wetting agent and formaldehyde as a hardening agent, as is well known in the art.
  • the pH of the prepared emulsion was 6.0.
  • a method of making a photographic base material comprising subjecting to corona discharge treatment a base material, the surface of which comprises polyethylene containing a compound represented by the general formula,
  • R is a hydrocarbon group of eight to 22 carbon atoms
  • R is hydrogen or a lower alkyl group
  • M is an organic amino group or a metal
  • p and q are integers
  • x and y are numbers and, where M is a metal, numbers determined by its valence.
