DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a photosensitive transfer material and an image forming method using the same. INDUSTRIAL APPLICABILITY The photosensitive transfer material and the image forming method according to the present invention are suitably used for producing a color filter used for a liquid crystal display or the like.

[0002]

2. Description of the Related Art Various dry-type image recording methods that do not use a liquid developer or the like have been conventionally studied. As a method for directly forming an image, a method using a composition that is cured by light has attracted attention. For example, see Japanese Patent Application Laid-Open
Nos. 7827 and 4-211252. On the other hand, as a method of forming an image by transfer, a method of moving (transferring) a color component of a predetermined recording material to an image receiving material using a thermal head or a laser is often studied.

In the former method using a composition which is cured by light, a latent image is formed by exposing to light and curing the composition which is cured by light contained in the recording material. A component contained in the unexposed portion, which acts on the color development or decoloration reaction by heating, moves in the recording material to form a color image. When using a recording material of such a method, first, light is exposed on the recording material through an image original, the exposed portion is cured to form a latent image, and then the recording material is heated to be uncured. A component that acts on the color development or decoloration reaction contained in the portion (unexposed portion) is moved to form a visible image. According to this method, a complete dry system that does not generate waste can be realized.

In recent years, with the development of image display devices, attention has been paid to color filters used in display devices, and higher performance thereof has been desired. The color filter must be capable of forming a high-definition pattern and have a uniform film quality.However, depending on the conventional general-purpose printing method, ink-jet method, micelle electrodeposition method, pigment dispersion method, etc. It was difficult to produce a color filter having a uniform film thickness without defects and capable of forming a high-definition pattern. As a method for manufacturing a new color filter, the transfer method using the dry system described above, which manufactures a color filter with uniform film quality by transferring and fixing the coloring layer created on the temporary support in advance to the filter substrate, is studied. Have been. When a color filter is manufactured by the transfer method, if there is unevenness on the surface that is in contact with the liquid crystal material, when liquid crystal is displayed, the orientation of the liquid crystal molecules is disturbed in the vicinity of the convex part, which causes display unevenness and a decrease in contrast. Therefore, it is an important issue to eliminate coating unevenness of the photosensitive resin layer containing a coloring agent and to improve coating surface properties.

[0005]

Here, to sequentially provide means that the respective layers are arranged in the stated order on the temporary support, and does not exclude the presence of other layers such as an intermediate layer and a protective layer.

(Photosensitive Resin Layer) First, the photosensitive resin layer will be described. This photosensitive resin layer is a layer containing a coloring agent, and constitutes a coloring layer when a color filter is formed. The photosensitive resin layer is preferably softened or tacky at least at a temperature of 150 ° C. or less, and is preferably thermoplastic. Most of the layers using the known photopolymerizable composition have this property, but some of the layers using the known photopolymerizable composition have a thermoplastic binder added or a compatible plasticizer. It can be further modified by addition.

As the colorant, for example, it is preferable to use a pigment from the viewpoint of light resistance and stability when used in a color filter. From the viewpoint that a pigment as a colorant can form a uniform colored layer, it is preferable that the pigment is uniformly dispersed in the photosensitive resin layer, and uniform dispersion is ensured or good light transmittance is achieved. In view of this, it is preferable to use a pigment having a particle size of less than 0.1 μm. The blending amount of the pigment is appropriately determined according to the coating amount per unit area so that a desired coloring concentration can be obtained after the coating layer is provided. The compounding amount varies depending on the coloring power of the pigment and the coating amount per unit area, and is 1 to the total solid content of the photosensitive resin layer.

(Thermoplastic resin layer) Next, the thermoplastic resin layer will be described. In the photosensitive transfer material of the present invention,
The resin constituting the thermoplastic resin layer has a substantial softening point of 8
It is preferably 0 ° C. or lower. Examples of the alkali-soluble thermoplastic resin having a softening point of 80 ° C. or lower include a saponified product of ethylene and an acrylate copolymer, a saponified product of styrene and a (meth) acrylate copolymer, and vinyltoluene and (meth) acrylic. At least one selected from a saponified acid ester copolymer, a poly (meth) acrylate, and a saponified material such as a (meth) acrylate copolymer such as butyl (meth) acrylate and vinyl acetate. Preferable but more “Plastic Performance Handbook”
(Edited by the Japan Plastics Industry Federation, All Japan Plastics Molding Industry Federation, published by the Industrial Research Council, October 2, 1968
Among them, organic polymers having a softening point of about 80 ° C. or lower and soluble in an alkaline aqueous solution can be used. In addition, even in the case of an organic polymer substance having a softening point of 80 ° C. or higher, various plasticizers compatible with the polymer substance are added to the organic polymer substance to lower the substantial softening point to 80 ° C. or lower. Is also possible. In addition, in order to adjust the adhesive force with the temporary support in these organic polymer substances, various polymers and supercooled substances, adhesion improvers or surfactants, as long as the substantial softening point does not exceed 80 ° C, It is possible to add a release agent and the like.

Specific examples of preferred plasticizers include polypropylene glycol, polyethylene glycol, dioctyl phthalate, diheptyl phthalate, dibutyl phthalate, tricresyl phosphate, cresyl diphenyl phosphate biphenyl diphenyl phosphate.

In the present invention, it is preferable to add a polysiloxane compound represented by the above general formula (1) to the coating solution of the thermoplastic resin layer. That is, when the thickness of the thermoplastic resin layer located between the support and the photosensitive resin layer is not uniform and has irregularities on the surface, the thickness of the thermoplastic resin layer is not negligible as described below. Therefore, it is considered that one of the reasons is that the irregularities also affect the upper photosensitive resin layer and hinder the formation of a uniform colored layer. When it is contained in the thermoplastic resin layer, the content is preferably 0.001 to 3% by weight, more preferably 0.01 to 0.3% by weight, in the thermoplastic resin layer (coating solution). When the content is 0.01% by weight or less, the effect of the addition is hardly obtained, and when the content exceeds 3% by weight, the uniformity of the coating solution tends to be reduced and cissing tends to occur. Since such a polysiloxane compound has the effect of improving the uniformity of the formed layer and the coated surface property, in the present invention, at least one of the above-mentioned photosensitive resin layer or thermoplastic resin layer has this polysiloxane compound. It is necessary to contain a siloxane compound. In a preferred embodiment, the polysiloxane compound represented by the general formula (1) is contained at least in the photosensitive resin layer, and more preferably contained in both the photosensitive resin layer and the thermoplastic resin layer.

The thickness of the thermoplastic resin layer is preferably at least 6 μm. This is because the thickness of the thermoplastic resin layer is 5 μm.
This is because if it is less than 1 μm, it is impossible to completely absorb irregularities of the underlayer of 1 μm or more. Further, the upper limit, the developability when remaining on the photosensitive resin layer side during transfer,
About 100 μm or less, preferably about 50 μm
m or less.

Depending on the transfer conditions of the photosensitive transfer material, the thermoplastic resin may protrude to the periphery during the transfer and contaminate the permanent support. In order to prevent this phenomenon, it is preferable that the thermoplastic resin used in the photosensitive resin layer and the thermoplastic resin layer be soluble in an alkaline aqueous solution. This is because any substance that can be dissolved in an alkaline aqueous solution can be easily removed by a subsequent treatment.

The alkaline aqueous solution may be the same as or different from the alkaline developer for the photosensitive resin of the present invention. The aqueous alkaline solution of the present invention is a dilute aqueous solution of an alkaline substance, and includes a solution to which a small amount of an organic solvent miscible with water is further added.

(Other layers) An intermediate layer can be provided between the photosensitive resin layer and the thermoplastic resin layer. In the intermediate layer, these layers are prevented from mixing when applied in a multi-layer coating, the adhesion between these layers is adjusted, and those which remain on the photosensitive resin layer side during transfer and exhibit a function of blocking oxygen are provided. And other various functions. For example, as those having an oxygen-blocking function, known ones can be used from those exhibiting low oxygen permeability which are dispersed or dissolved in water or an aqueous alkali solution.

The thickness of the intermediate layer is very thin, about 0.1 to 5
μm, especially 0.5 to 2 μm. If it is less than about 0.1 μm, the oxygen permeability is too high, and if it exceeds about 5 μm, it takes too much time during development or when removing the intermediate layer.

(Preparation of photosensitive transfer material) The photosensitive transfer material of the present invention is prepared by applying a thermoplastic resin layer solution on a temporary support,
The thermoplastic resin layer is provided by drying, then a solution of an intermediate layer material composed of a solvent that does not dissolve the thermoplastic resin layer is applied on the thermoplastic resin layer, and then dried, and then the photosensitive resin layer is dissolved in the intermediate layer. Apply and dry with a solvent that does not.

Alternatively, a solution of a photosensitive resin layer material consisting of a solvent that does not dissolve the layer is applied on the thermoplastic resin layer and dried.

Alternatively, a photosensitive resin layer is provided on another cover sheet, and both sheets of a sheet having a thermoplastic resin layer (and optionally an intermediate layer) on the temporary support are combined with the photosensitive resin layer. A temporary support having a thermoplastic resin layer is prepared by laminating the thermoplastic resin layers (intermediate layers in some cases) so as to be in contact with each other, or as another covering sheet,
The thermoplastic resin layer is advantageously produced by laminating a sheet comprising a photosensitive resin layer (and optionally an intermediate layer) on a cover sheet.

Here, the technique of peeling between the intermediate layer and the thermoplastic resin layer when removing the temporary support after laminating the photosensitive resin layer and the permanent support is disclosed in JP-A-5-72724.
Japanese Patent Application Laid-Open No. 5-80503 discloses a technique for peeling between a thermoplastic resin layer and a temporary support.

When the temporary support is peeled off, the film and the human body may be charged and may receive an unpleasant electric shock. Further, dust is drawn from the surroundings due to the charging, and unexposed portions are formed in the subsequent exposure process. This may cause pinholes. In the photosensitive transfer material of the present invention, in order to prevent electrification, a conductive layer is provided on at least one surface of the temporary support to reduce its surface electric resistance to 10 ¹³ Ω or less, or to the temporary support itself. It is possible to use a conductive material having a surface electric resistance of 10 ¹³ Ω or less. In order to impart conductivity to the temporary support, a conductive substance may be contained in the temporary support, or a conductive layer may be provided on the support. For example, Japanese Patent Application Laid-Open No. 5-80503 describes in detail. Known techniques described may be used.

(Image Forming Method) Next, an image forming method using the photosensitive transfer material of the present invention will be described. First, the cover sheet of the photosensitive transfer material is removed, and the photosensitive resin layer is bonded to the substrate under pressure and heat. Conventionally known laminators and vacuum laminators can be used for bonding, and an auto-cut laminator can be used to further increase the productivity. Thereafter, the temporary support is peeled off, exposed through a predetermined mask or the like (in some cases, a thermoplastic resin layer or an intermediate layer), and then developed. The development is carried out by immersing in a solvent or an aqueous developer, particularly an alkaline aqueous solution, or applying a spray of the developer from a spray, and further rubbing with a brush or irradiating with an ultrasonic wave by a known method. . By using a photosensitive transfer material having a photosensitive resin layer colored in different colors and repeating this process a plurality of times, a multicolor image can be formed.

Since the photosensitive transfer material of the present invention has a uniform colored layer, it can be used for a wide variety of purposes and can be used for any purpose as long as it relates to the formation of multicolor images. In particular, since a uniform filter layer can be formed, it can be suitably used for producing a color filter for a liquid crystal display or the like. As a substrate (image receiving material) for producing a color filter, a known glass plate, a soda glass plate having a silicon oxide film formed on the surface, or the like is used.

The coating solution for the photosensitive resin layer was prepared by the following method. First, 3 having each hue is obtained by the following method.
Dispersions of the various pigments were made. 360 g of each of the above pigments, 36 g of dispersant (Solsperse 24000, manufactured by Zeneca),
740 g of a binder resin solution (40% by weight of the above-mentioned benzyl methacrylate / methacrylic acid copolymer methylcellosolve acetate solution) was kneaded (s1 manufactured by Moriyama Seisakusho).
According to -1), the mixture was kneaded for 30 minutes to obtain a pigment composition. Next, 900 g of a dispersing solvent (methyl cellosolve acetate) was added, and the mixture was further dispersed for 360 minutes using a media mill (Dynomill KDL-PILOT manufactured by Willie E. Bakochen). To this dispersion was added pentaerythritol tetraacrylate, Michler's ketone, etc.
The composition was as follows.

Further, a cover sheet of polypropylene (thickness: 12 μm) was pressed on the photosensitive resin layer to prepare red, blue, green and black photosensitive transfer materials.

Using this photosensitive transfer material, a color filter was prepared by the following method. The coating sheet of the red photosensitive transfer material was peeled off, and the photosensitive resin layer surface was pressed on a transparent glass substrate (thickness: 1.1 mm) using a laminator (VP-II manufactured by Taisei Laminator Co., Ltd.) (0.8 kg / cm
² ), bonding was performed by heating (130 ° C.), and then peeled off at the interface between the temporary support and the thermoplastic resin layer, and the temporary support was removed.

Next, exposure was performed through a predetermined photomask, and the thermoplastic resin layer and the intermediate layer were removed with a 1% aqueous solution of triethanolamine. At this time, the photosensitive resin layer was not substantially developed. Next, the photosensitive resin layer was developed with a 1% aqueous solution of sodium carbonate to remove unnecessary portions, thereby forming a red pixel pattern on a glass substrate. Next, on the glass substrate on which the red pixel pattern was formed, a green photosensitive transfer material was attached in the same manner as described above, peeled, exposed,
Development was performed to form a green pixel pattern.

The same process was repeated with a blue photosensitive transfer material to form a color filter on a transparent glass substrate.
In these steps, the adhesion between the glass substrate and the photosensitive resin layer was good. The filter layer of the obtained color filter was uniform in both film thickness and film quality, and had good characteristics as a liquid crystal color filter.

(Comparative Example 1) A color was prepared in the same manner as in Example 1 except that the polysiloxane-based compound (the exemplified compound) was not added to the photosensitive resin layer coating solution of each color used in Example 1. When the filter was prepared, application unevenness occurred, and a color filter having a uniform film thickness and quality could not be obtained, which was not suitable for practical use.
