Problems solved by technology

In these patent documents, with respect to the particle size distribution of the matting agent, these patent documents neither disclose nor suggest, so it may be particularly difficult to expect excellent anti-blocking properties of the image receiving paper by controlling the particle size distribution of the matting agent, and can form images with high image quality
[0008] In order to obtain an image quality comparable to that of a photograph, it is required that impurities do not intrude into the surface of the toner image-receiving layer of the image-receiving paper for electrophotography. Therefore, the coating liquid for the toner image-receiving layer containing a matting agent Filtration becomes necessary, however, when the particle size distribution of the matting agent is large, causing the disadvantage of the filter being clogged

Embodiment 1

[0395]

[0396] -Preparation of base paper-

[0397] The pulp stock was prepared by the following method: 25% by mass of LBKP (broadleaf kraft pulp, bleached pulp) made from Robinia pseudoacacia was beaten to 30 ml Canadian standard freeness by using a disc refiner with respect to 100% by mass of the pulp stock And the obtained pulp material was mixed with 75% by mass of a pulp material obtained by beating LBKP (broadleaf kraft pulp, bleached pulp) made of poplar to 300 ml Canadian standard freeness using a disc refiner. The prepared pulp stock was mixed with 1.3 mass % of cationic starch (manufactured and sold by Nihon N.S.C. Company; trade name: CATO 304L), 0.145 mass % of anionic polyacrylamide with respect to 100 mass % of the paper stock (polyacrilamide) (manufactured and sold by Seiko P.M.C. Corporation; trade name: Polyacron ST-13), 0.285% by mass of alkyl ketene dimer (manufactured and sold by Arakawa Chemical Industries, Ltd.; trade name: Sizepine K) , 0.32% by mas...

Embodiment 2 and comparative example 1 to 5

[0435] In substantially the same manner as in Example 1, except that the matting agent particles of the coating liquid used to prepare the toner image-receiving layer in Example 1 were changed to those shown in Table 5 below, each The toner-image-receiving sheets for electrophotography of Example 2 and Comparative Examples 1 to 5, and in substantially the same manner as in Example 1, images were formed on the prepared toner-image-receiving sheets.

[0436] Particles (Matting Agent)

[0437] Among them, as components of each matting agent, XX08S contains cross-linked PMMA resin, LE1080 contains polyethylene resin, EA 209 contains ethyl acrylate resin, CL2080 contains polyethylene resin, and SBX-12 contains cross-linked polystyrene resin.

Embodiment 3

[0439] Except that the aqueous dispersion of the polyester resin as the self-dispersible water-dispersible polymer in Example 1 was changed to a self-dispersible water-dispersible polyester resin emulsion (manufactured and sold by Unitika Ltd.; trade name: Elitel KZA-1449; solid content is 35% by mass, glass transition temperature (Tg) is 46°C, number average molecular weight is 6,500, molecular weight distribution is 3.2, volume average diameter is 43nm, and flow start temperature is 100.4°C), In substantially the same manner as in Example 1, the toner image-receiving sheet for electrophotography of Example 3 was prepared, and in substantially the same manner as in Example 1, the prepared toner image In the receiver paper, an image is formed.

Abstract

The object of the present invention is to provide an image-receiving sheet for the electrophotography which is excellent in the adhesion resistance and can form an image having a high image quality and an effective manufacturing method thereof , and also a image-forming process and image-forming system for the electrophotography using the image-receiving sheet for the electrophotography. For this object, the present invention provides an image-receiving sheet for the electrophotography comprising a support and a toner image-receiving layer disposed on at least one surface of the support which comprises at least a polymer used for producing the toner image-receiving layer, wherein the image-receiving sheet for the electrophotography comprises particles and the particle size distribution (standard deviation / volume average particle diameter) of the particles projecting out of the most outer surface of the toner image-receiving sheet for the electrophotography is 0.4 or less.

Description

technical field [0001] The present invention relates to an image-receiving paper for electrophotography that is excellent in anti-adhesion and can form an image with high image quality and an efficient manufacturing method thereof, and also relates to an electronic device using the image-receiving paper for electrophotography An image forming method and an image forming system for photography. Background technique [0002] Conventionally, since electrophotography can be output on general-purpose paper such as plain paper and Dowling paper, it is used for output devices of copiers or personal computers, however, when image information such as human faces and landscapes are output as photographs on On general-purpose paper, the resulting image has poor gloss or the image is different from the real image, therefore, special paper for electrophotography is required, and many attempts to image-receiving paper for electrophotography have been proposed in order to obtain special pa...
