Abstract

PURPOSE:To prevent the positional deviation of transferred images to a practicably sufficient degree by transferring the images in the state of superposing respective sheets and a substrate having a layer contg. rubber. CONSTITUTION:The image sheet 1 on which the image 1a is formed and the image receiving sheet 2 which receives the image are superposed and the substrate 4 having the slippage preventive layer 3 contg. the rubber on the sheet 2 side is superposed thereon. These sheets and substrate are passed between, for example, a pair of rolls 5 and 5 in order to integrally pressurize the same or to execute both the pressurization and heating. Since the slippage preventive layer 3 contains the rubber in such a manner, the generation of the slippage with, for example, the image receiving sheets 2 is obviated and the image receiving sheets 2 and the substrate 4 is eventually integrated. Warping and wrinkling of the image receiving sheet 2 are prevented by the rigidity of the substrate 4. The positional deviation of the transferred images is prevented in this way at the time of transferring the images of respective colors to the image receiving sheet.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an image transfer method for creating color proofs and the like.

[Conventional technology]

It is well known that a color sheet for color proofing (called a color proof) is used to save the labor and time of proof printing, which is performed as a pre-printing process in multicolor printing.

Several proposals have been made for the creation of this color proof.
No. 1, Japanese Patent Publication No. 47-41830, Special Publication No. 56-501
No. 217, JP-A-59-97140, JP-A No. 60-286
No. 49 and US Pat. No. 3,775,113.

In any case, the process usually includes the step of overlapping an image sheet on which an image is formed and an image-receiving sheet that receives the image, and transferring the image to the image-receiving sheet by applying pressure or heating/pressing. There is. Unlike the method of forming an image by exposing the photosensitive layer transferred onto the transfer paper, the method for creating a color proof that includes this step involves sequentially transferring each color of the formed image, so each color It is important that no misalignment occurs between images.

However, when passing an overlapping image sheet and image receiving sheet between a pair of rollers for transfer, for example, it is difficult to avoid misalignment between the images due to misalignment, warping, or wrinkles between the two sheets. It was difficult.

Therefore, in Japanese Patent Application Laid-open No. 60-255497,
A means for solving the above problem has been disclosed in which both sheets are sandwiched between a support such as a metal plate and a cover sheet and passed between a pair of rollers.

[Problem to be solved by the invention]

However, although the prior art described in the above-mentioned publication can certainly prevent misalignment between transferred images to some extent, misalignment between the support and the sheet may occur, and the effect is not sufficient.

SUMMARY OF THE INVENTION Therefore, the main object of the present invention is to provide an image transfer system that can prevent misalignment of transferred images caused by wrinkles on images and image-receiving sheets or misalignment between image sheets to a practically sufficient degree. The purpose is to provide a method.

[Means to solve the problem]

The above problem is solved by a method of transferring an image by overlapping an image sheet on which an image is formed and an image-receiving sheet that receives the image, or by applying pressure or heating. This problem can be solved by transferring the image while superimposing the support with a support having a layer that corresponds to the problem.

[Specific structure of the invention]

The present invention will be described in further detail below.

First, to outline the method of the present invention with reference to FIG. 1, image 1a
The image sheet 1 on which the image is formed is superimposed on the image receiving sheet 2 that receives the image, and preferably the image receiving sheet 2 is superimposed on a support 4 having an anti-slip layer 3 containing alligator rubber. For example, it is passed between a pair of rollers 5, 5 in order to apply pressure integrally or to perform pressurization and heating at the same time.

In this embodiment, since the anti-slip N3 contains rubber, no misalignment occurs between it and the image-receiving sheet 2, and as a result, the image-receiving sheet 2 and the support 4 become integrated. The image receiving sheet 2 will not be warped or wrinkled due to the rigidity of the support 4. As a result, when transferring images of each color to an image receiving sheet, it is possible to prevent misalignment of the transferred images.

Here, the anti-slip layer 3 may be formed into a film and simply laminated on the support 4, or may be completely bonded (for example, by a lamination method) using an adhesive or a primer.

Alternatively, a coating solution obtained by dissolving and dispersing a rubber-containing material for forming the anti-slip layer in a solvent may be applied onto the support and dried.

The thickness of the anti-slip layer is not limited as long as it does not impede the thermal conductivity of the support so that it conducts a certain amount of heat during heating, but it is preferably 0.1 to 300 μm.
It is m.

When heating is also performed during transfer, the support is preferably made of a material with good thermal conductivity, and generally a metal plate is suitable. Further, a plastic plate or the like may be used in some cases. The thickness of the support is 10 μm to 5 μm, especially 0.5 μm.
1 to 1.5 t* is preferred.

Furthermore, it is desirable for the support to be as rigid as possible in order to prevent wrinkles and warpage.

A typical example of means for applying pressure or applying pressure/heating during transfer is passing the above-mentioned overlapping material between one pair or multiple pairs of rollers in the conveying direction, but when heating is performed, One or both of the pair of rollers may be a rotary roll.

Alternatively, a press method using a flat plate or the like may be used.

The pressing force is 0.5 to 100 kg/cts, especially 5 to 2
Approximately 0 kg/cm" is preferable, and the heating temperature is 70 to 15
0t, especially 80-130°C is preferred.

Furthermore, the support having the anti-slip layer may be provided on either side of the image sheet or on both sides of the image/image-receiving sheet, although this will complicate the process when obtaining a multicolor image. . Further, the anti-slip layer according to the present invention may be transferred by combining a support and a cover sheet made of a PET film or the like described in the above-mentioned publication, and sandwiching a superimposed image/image-receiving sheet therebetween.

Now, the anti-slip layer in the present invention is a layer that contains rubber and utilizes this as an anti-slip effect. Although natural rubber can be used as the rubber, synthetic rubber is preferable.

Examples of this synthetic rubber include styrene/butadiene rubber, butadiene rubber, isoprene rubber, chloroprene rubber, urethane rubber, polysulfide rubber, tetrafluorinated ethylene/propylene rubber, acrylic rubber, shrimp chlorohydrin rubber, ethylene vinyl acetate rubber, and 1,2-polymer rubber. Butadiene rubber, thermoplastic elastomers (e.g. styrene, olefin, urethane, polyester, polyamide, fluorine), ethylene/propylene copolymer, ethylene/propylene/diene copolymer, nitrile/butadiene rubber,
Examples include butyl rubber, fluororubber, chlorosulfonated polyethylene, propylene oxide rubber, ethylene/acrylic rubber, norbornene rubber, silicone rubber, and silicone rubber is particularly preferred. This may be used in combination.

Furthermore, anti-aging agents, stabilizers, fillers, colorants, etc. may be added.

The silicone rubber suitable as the rubber contained in the anti-slip layer is preferably one whose main component is a linear organic polysiloxane having the following repeating units and a molecular weight of several thousand to several tens of edges.

These silicone rubbers are also available as commercial products, such as rYS-3085J manufactured by Toshiba Silicone Corporation.

Other useful silicone rubbers are produced by reacting the base polymers listed above with H-type silicone oils having the following repeating units, or by producing silicone base polymers in which approximately 3% of R is vinyl groups. It can also be obtained by an addition reaction with H-type silicone oil or a reaction between the H-type silicone oils.

Moreover, in order to improve the strength of silicone rubber, filler can also be mixed.

Silicone rubber premixed with fillers is commercially available as silicone rubber stock or silicone rubber dispersion.
If it is preferable to obtain an anti-slip layer with a silicone rubber film, a dispersion of RTV or LTV silicone rubber is preferably used. Examples include rsyl Off 23J manufactured by Toray Silicone;
There are silicone rubber dispersions for paper coating such as rSRX-257J and rSH237J.

Preferably, the silicone rubber layer further contains a silane coupling agent to improve adhesion to the support.

In order to obtain a multicolor image using this image sheet and image-receiving sheet, first, a first-color colored image is formed on a first-color colored image-forming material, and a small amount of the colored image is transferred to an image-receiving sheet and a support is formed. Further, after forming a second color colored image on the second color colored image forming material, the second color register mark image formed accordingly is registered with the first color register mark image on the image receiving sheet. While doing this, add the second color on the first color image.
The colored image is transferred and the support is peeled off to obtain a two-color matched image. Similarly, colored images of the third and fourth colors are also transferred onto the image-receiving sheet to obtain a multicolor image. In some cases, this multicolor image may be indirectly transferred onto another transfer material to obtain a multicolor image (hereinafter referred to as indirect transfer method).

Incidentally, this type of method is disclosed in JP-A-47-41830, JP-A-59-97140, JP-A-60-28649 and US Pat. No. 3,775,113.

Since the image on the image sheet is finally transferred to the image receiving sheet, the image is efficiently transferred to the image receiving sheet, and the image on the support after the image transfer is maintained. In order to facilitate JI release, it is preferable to subject the surface of the support to a mold release treatment using an appropriate 18 oily substance, or to provide a mold release layer on the support.

As the oil-based substance, for example, silicone resin, fluororesin or fluorine-based surfactant can be used, and as the mold release layer, for example, alcohol-soluble polyamide, alcohol-soluble nylon, copolymer of styrene and maleic anhydride can be used.

is within the range of

The support for the colored image-forming material for forming the image-receiving sheet used in the present invention, preferably a transparent support, includes:
A polyester film, particularly a two-wheel stretched polyethylene terephthalate film, is preferred from the viewpoint of dimensional stability against water and heat, but acetate film, polyvinyl chloride film, polystyrene film, polypropylene film, and polyethylene film may also be used.

The colored image forming layer is imagewise removed by development following imagewise exposure to form a colored image.

The colored image forming layer may be a colored photosensitive layer containing both a colorant and a photosensitive composition, or the coloring agent layer and photosensitive layer may be separate. The layer order of the colorant layer, photosensitive layer, and colored photosensitive layer is not limited. Further, a heat-fusible layer (hereinafter referred to as intermediate heat-fusible layer) may be provided between the support and the colored image forming layer. The outermost layer of the colored image-forming layer may be a layer that can be adhered to the image-receiving sheet, or a heat-fusible layer may be provided on the colored image-forming layer.

Various materials have been known for the above-mentioned photosensitive compositions, and commercially available products are also easily available. The photosensitive composition used undergoes a chemical change in its molecular structure in a short period of time when exposed to actinic rays, changing its solubility in solvents, and when a certain type of solvent is applied. includes all compounds such as monomers, prepolymers, and polymers that are dissolved and removed by exposed or unexposed areas. Examples of photosensitive compositions that can be used include photocrosslinkable photosensitive compositions, such as those made by esterifying polyvinyl alcohol with cinnamic acid, which are so-called negative-positive type compositions in which the solubility of exposed areas decreases. There are resin systems, systems in which diazonium salts and their condensates are mixed with polyvinyl alcohol, polyvinylpyrrolidone, polyacrylamide, etc., and systems in which aromatic azide compounds are used as photocrosslinking agents and mixed with binders such as cyclized rubber. Photosensitive resins using photoradical polymerization or photoionic polymerization can also be used. Further, as a so-called positive-positive type resin that increases solubility in the exposed area, there is a photo-soluble resin system typified by a combination of naphthoquinone diazide and novolac resin.

Commercial products of such photosensitive compositions include "KPR", 1KOR"KMER', manufactured by Eastman Kodak Company, USA.
, ``AZ-340'', ``AZ-1'' manufactured by Shipley, USA

As the coloring substance used as the colorant used in the present invention, dyes and pigments can be used. In particular, when used for color proofing, pigments and dyes in the usual colors required for that purpose, such as yellow magenta, cyan, and black, are required, but in addition, metal powders, white pigments, fluorescent pigments, etc. used.

0 The content ratio of the colored substance can be determined by a method known to those skilled in the art, taking into account the target optical density and removability to the developer. For example, in the case of dye, the content is 5% by weight. In the case of pigments, the content is suitably 5% to 90% by weight.

Since the photosensitive composition and coloring agent described above have poor or poor film-forming properties, it is preferable to use a binder to form a film.

As this binder, a polymer compound that is film-forming, solvent-soluble, and capable of being dissolved or swollen in a developer is used.

Specific examples of binder polymer compounds suitably used for the colored recording include acrylic acid, methacrylic acid, alkyl esters or sulfoalkyl esters thereof,
Phenol resin, polyvinyl butyral, polyacrylamide, cellulose derivatives such as ethyl cellulose, cellulose acetate/butyrate, cellulose acetate propionate, cellulose acetate, benzyl cellulose, cellulose propionate, other polystyrene, polyvinyl chloride, chlorinated rubber, polyisobutylene, Examples include polybutadiene, polyvinyl acetate, and copolymers thereof, cellulose propionate, cellulose acetate phthalate, and the like.

In addition to the above-mentioned materials, a plasticizer, a coating property improver, etc. may be added to the above-mentioned image forming layer, if necessary.

Plasticizers include various low-molecular compounds such as phthalate esters, triphenyl phosphates, maleate esters, and coating properties improvers include surfactants such as fluorine surfactants and ethyl cellulose polyalkylene ether. Examples include nonionic surfactants.

On the other hand, as the above-mentioned intermediate heat-fusible layer, one that is transparent and non-adhesive at room temperature, but can be heat-fusible in the temperature range of 80°C to 160°C is suitable.

For this purpose, the following film-forming thermoplastic resins having a softening point of 70°C to 140°C are used. For example, olefin (co)polymer, vinyl chloride (co)polymer, vinylidene chloride (co)polymer, vinyl acetate (co)polymer, (meth)acrylic acid ester (co)polymer, styrene/(meth)polymer Acrylic ester copolymers, polyesters, vinyl butyral resins, chlorinated rubber, cellulose derivatives, preferably styrene/(meth)acrylic ester copolymers, polyesters, etc., which may be used alone or in combination; may be used in combination with other resins or plasticizers.

The suitable thickness of the heat-adhesive material is in the range of 1 to 20 μm,
Particularly preferred is a range of 2 to 8 μm.

It is better to make the thickness of the heat-fusible layer equal to or greater than the thickness of the colored image forming layer, so that the colored image formed on the heat-fusible layer can be heated, pressed, and transferred to the surface of the image-receiving material. At the same time, even the minute non-image area, that is, the narrow overhead heat-adhesive layer surrounded by the large image area, is effectively fused to the surface of the image-receiving material, resulting in an even image.
Moreover, a good transferred image can be obtained.

In order to produce the colored image forming material according to the present invention, the above-mentioned layer-constituting material is dissolved in an appropriate solvent, and the above-mentioned mold release treatment is carried out.
Alternatively, they may be applied sequentially or simultaneously to a support having an undercoat layer.

As a solvent, water, methanol, ethanol, acetone, ethyl acetate, methyl cellosolve, ethyl cellosolve,
dioxane, methyl ethyl ketone, cyclohexanone,
Diethylene glycol monomethyl ether, T-butyrolactone, tetrahydrofuran, methylene chloride,
Examples include ethylene chloride, dimethyl sulfoxide, dimethyl formamide, etc., and these can be used alone or in combination of two or more.

Note that various light sources such as an ultra-high pressure mercury lamp, a tungsten lamp, a mercury lamp, a xenon lamp, a fluorescent lamp, a CRT light source, and a laser light source are used for imagewise exposure to form a colored image.

For development, the developer shown in the above-mentioned conventional example can be used.

As the image-receiving sheet, white paper such as art paper, coated paper, high quality paper, synthetic paper, etc. can be used. In the indirect transfer method, the obtained colored image is temporarily transferred and laminated onto a temporary image-receiving sheet, and then transferred again onto a transfer surface such as art paper, coated paper, synthetic paper, or the like. The image-receiving sheet used in this indirect transfer method may be one in which an image-receiving layer containing a thermoplastic organic polymer is provided on a support, or one in which a photo-sensitive image-receiving layer is provided on a support.

The support used when forming this transfer material is as follows:
Various materials can be used, but for example, polyester film, especially biaxially oriented polyethylene terephthalate film, is preferred in terms of dimensional stability against water and heat, and acetate film, polyvinyl chloride film, polystyrene film, polypropylene film is preferred. Films may also be used.
