Abstract

PURPOSE:To obtain photographic paper with superior surface smoothness by coating both sides of paper having a specified value or above of surface smoothness measured by means of a Bekk smoothness tester with polyethylene. CONSTITUTION:Pulp of a broadleaf tree composed of fine and short fibers is used. The fibers are well dispersed, and by increasing the pressure of a calender, the unevenness of the surface of paper is reduced to provide 95'' surface smoothness measured by means of a Bekk smoothness tester. Both sides of this paper are coated with polyethylene in 15-40mum thickness by means of an extruder and a laminator. The emulsion layer side of the paper is coated with polyethylene contg. 5-20wt% TiO2 pigment. By finishing the roll surface of the laminator to a mirror surface, a support for photographic paper having superior surface smoothness and a glossy surface is obtd.

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a support for photographic paper, and particularly to a support for photographic paper that has good optical surface smoothness. Photo stamp - Both sides of the paper for the purpose of quick cleaning of the paper? Waterproof supports damaged by polyethylene are already in practical use. The surface shape of the photographic paper used as a waterproof support can be glossy, matte or silky, etc.1
・Those with 1 t'L% are manufactured and commercially available,
The shape of the surface of these photographic papers is such that the image embossed on the surface of the polyethylene 1- on the emulsion side of the support material appears directly on the surface of the photographic paper. Of all the surface shapes such as this, the smooth 15" open-light θ surface with no pattern is the most widely preferred, and is the most widely produced and sold 71. What is preferable for this glossy photographic paper is that the screen has as few minute irregularities as possible and has a mirror-like smooth surface.

The present invention V relates to a support for photographic paper having excellent surface smoothness f'. With conventional photographic paper using baryta paper, there is no drying process, which is the final step of the development process.
'l) The surface of the rotary tube 1 was polished to a near-mirror surface. However, it is waterproof and has 1 ton of seals! il Xil: is the ferrotype mentioned above.
Since it is finished without going through 1° 1 process, the surface of the finished photographic paper itself is 111% of the quality of 1 screen. . EO[! The thickness of the photographic emulsion layer of the ++ paper is extremely thin, on the order of 10 microns, so it is exactly the same as the flatness of the surface of the photographic paper and the smoothness of the six sides of the support. Therefore, in order to obtain a beautiful field surface, the surface of the support must be smooth for V).

The most common method for coating polyethylene to obtain a water-resistant support is stretch coating, that is, coating the surface of running paper by casting polyethylene that has been melted in a bath. The present invention also relates to a water distribution support with good flatness obtained by extrusion coating. Extrusion - 1 - Smoothness of the surface of polyethylene-coated paper produced by lining? As a method to do the same as above, is there a #'ik polyethylene layer? Thickening, concave basting pressure when covering polyethylene? However, the present inventor has clarified that 41F is the most effective way to raise the surface of the paper, which is the base material, and has accomplished the present invention.

In the VCLIL of the present invention, if the paper surface smoothness value measured with a Beck type smoothness meter increases by 5 seconds or more, a glossy surface support with a sufficiently good flatness/it ratio can be obtained. The thickness of the filter paper in the water-resistant support of the present invention is 10f7m2 to 1-1, respectively.
The thickness of the polyethylene layer is 75 microns to 23θ microns on both sides. Further, the polyethylene layer on the emulsion side is impregnated with a saponified titanium pigment of 1% to 20% by weight (2).

Both the support and both sides were 21i chrome, and a glossy surface support was obtained by using the surface of a cooling roll of a laminator that produced poly-J-ethylene + mi on the photographic emulsion side. These supports were coated with an ordinary gelatin/silver halide photographic aperture i11 of 114 yuan,
Visually compare the smoothness of the photographic paper screen size 5:
i4 As a result, the smoothness of all the A/ and flat λ papers was excellent. However, the one using AJ paper (/J', poor smoothness, and as a glossy surface print) was unsatisfactory. Furthermore, when I compared it with the A-2 and the A-2, I found that the photographic paper made from the same AFx paper was superior in its smoothness.
