Abstract

PURPOSE:To dispense with devices for coating, drying, exposing, developing, etc., by laminating a scribable layer low in resistivity and a dielectric scribable layer on a transparent film support. CONSTITUTION:The low resistivity scribable layer is formed on the transparent film support by using a coating fluid prepared by mixing an electrically conductive resin, a dye, a pigment, a filler, etc., with an alkyd resin or the like, and dissolving or dispersing them in an org. solvent. Then, the dielectric scribable layer is formed on this layer by using a coating fluid prepared by dissolving or dispersing a mixture of a styrene-modified alkyd resin, an alkyd resin, a filler, a pigment, etc., in an org. solvent. Since this scribable electrostatic recording film uses no photosensitive material, a coating device, a drying device, an exposing device, a developing device, etc., are not necessary.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an electrostatic recording film having scribing properties that allows a positive or negative image to be printed directly on a scribing surface using an electrostatic plotter device. It is.

[Conventional technology]

In the field of conventional cartography, scribe base films are used as cartographic materials.

When producing a photoengraving plate from the survey original drawing using the above-mentioned scribe base film, negative original drawings for printing plates of each color are required.In this case, the survey original drawing is used as a master sheet and a black plate and a template are printed on the scribe base film. , each pattern for the brown plate was coated by a method called stenciling, and each color separation plate was created by photographic processing.

[Problem that the invention seeks to solve]

Conventional plate making methods using scribe base films have had various problems.

For example, applying and drying a photosensitive material for molding is troublesome, and in order to make it easier for the photosensitizer to be applied onto the scribe base when applying a water-based photosensitive material, the photosensitive material must adhere well to the scribe. , and it is necessary to apply an undercoat that is well wetted, but this has the disadvantage that it reduces the sharpness of the image when scribing.

In addition, photosensitive materials have a short pot life, so they must be remixed each time they are used, and there are problems in handling, such as the need to store photosensitive materials in a cool, dark place.

Furthermore, there are problems in workability, such as the need to darken the room in order to prevent fogging of the photosensitive material during exposure.

There is also a method of directly plotting with an automatic plotter (autoplotter), but this method is suitable for quadratures where the plotting accuracy is about 1/2,000, but it is 1/25,000 to 115.
In the 0.000 map, jagged lines occur in curved portions, and the beginning and end of scribing do not match.

In reality, it is done by hand-drawing method because of the drawbacks such as.

It has a number of drawbacks, such as:

[Means for solving problems]

In order to eliminate the above-mentioned drawbacks, the present invention does not rely on the conventional molding method using photosensitive materials, but instead uses CAD (Comp
