Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises an image receiving layer capable of transfer printing with a resin melt type ink ribbon, and the image receiving layer is a halftone dot.
It is a ticket paper formed in the shape of a line or a line, and can be suitably used for a ticket or an admission ticket for an automatic ticket gate that passes through the routes of a plurality of railway companies.

[0002]

2. Description of the Related Art In recent years, with the automation of ticket gates on railways, etc., an automatic ticket gate system has been rapidly introduced, and even the currently used ticket or admission ticket is compatible with these ticket gate systems. The magnetic recording layer for magnetic recording is provided on the surface opposite to the image receiving layer.

[0003] Conventionally, a ticket paper for a ticket of this type (including a ticket, a one-day ticket, and an admission ticket) is intended for many uses (long-term use) like a commuter pass. Since the physical strength of the base material itself is not very necessary, on the other hand, in addition to the printing stability and imprintability of the image receiving layer and the recording stability of magnetic recording, troubles in the transport system of the automatic ticket gate system are not caused. Not required.

[0004]

In the conventional ticket paper having the above-mentioned structure, a desired character, numeral, symbol or the like (hereinafter referred to as "character") is formed on the ticket paper by using the resin melting type ink ribbon. When printing on the image receiving layer of
From the relationship with the ink transferability of resin melt type ink ribbon,
It is composed of a resin material whose main component is a thermoplastic resin.

Therefore, since the resin material used for the image-receiving layer and the resin-melting type ink ribbon has a thermoplastic resin as a main component, it is excellent in abrasion resistance, chemical resistance, stain resistance, etc. It can be said that the ticket paper is suitable for the ticket gate system. However, depending on the purpose and use of the ticket paper that allows you to get on (via) multiple routes of different railway companies, it is possible to determine whether it is possible to get on by using a seal stamp or a stamp with a stamp or a writing instrument such as a ballpoint pen. It may display such as whether it is ticket paper,
Also, instead of the conventional ticket gates and ticket inspection methods (methods of punching or embossing the ticket paper), a method of preventing punch scraps and marking with excellent operability is being used. is there.

However, since the image-receiving layer of the conventionally used ticket paper contains wax in addition to the thermoplastic resin, the surface of the image-receiving layer is made of red ink, stamp ink or ink such as ballpoint pen. There is no property of absorbing the so-called, so-called imprintability, whether or not it is possible to get on multiple routes of different railway companies by direct stamping on the surface of the image receiving layer, imprinting using stamps or writing instruments such as ballpoint pens, or effective It was not possible to display whether or not the boarding ticket was good.

As a means for solving this problem, as disclosed in, for example, Japanese Patent Laid-Open No. 62-62793, as a heat-transferred sheet, a receptor for receiving a dye transferred from the heat-transfer sheet during heating is received. It is known that a non-receptive layer (imprintable layer) is partially provided directly on the layer, but the non-receptive layer (imprintable layer) is directly provided on this receptive layer.
When the non-receptive layer (imprintable layer) is formed, the receptive layer is attacked by the solvent (solvent) of the non-receptive layer (imprintable layer), and the components of the receptive layer and the non-receptive layer (imprintable layer) Layer with characteristics)
In some cases, the components of (1) were mixed with each other to impair the absorbability of ink (so-called imprintability) of stamps, stamps, ballpoint pens, and the like.

As a means for solving these problems, the present applicant proposes in Japanese Patent Application No. 5-60397 to provide a marking layer on a part of the image receiving layer of a thermal transfer recording medium via a barrier layer. did. However, this configuration also has points to be improved in terms of the manufacturing process and the manufacturing cost, and since the place where the marking layer is provided is limited, the position of the marking layer may be difficult to be visually detected easily in some cases. It was An object of the present invention is a boarding paper provided with an image-receiving layer capable of printing characters and the like on a resin-melting type ink ribbon which has been conventionally used, and which has image-receiving aptitude and sufficient printing aptitude of a resin-melting type ink ribbon. The purpose of the present invention is to provide a ticket paper which is easy to hold, easy to manufacture and low in cost.

00 μm] on one side as a material for magnetic recording with a coercive force of 2
750 (Oe: Oersted) Ba-ferrite and an aqueous acrylic resin emulsion are dispersed and mixed to form a magnetic paint. The magnetic paint is dried with a gravure coater to a film thickness of about 10
It was formed to have a thickness of μm (not shown).

The magnetic characteristics of the formed magnetic recording layer were a residual magnetic flux density of 1.4 (Mx / cm) and a squareness ratio of 0.85.

Next, a coating material having the following composition was applied to the other surface of the substrate 1 having a Bekk smoothness of about 100 seconds and a halftone dot ratio of 7:
Printing was performed by an offset printing method so that the number of lines was 0%, the number of lines was 200, and the angle was 45 degrees, and the coating film was dried by ultraviolet irradiation to form an image receiving layer 2 having a dry thickness of about 2 μm.

At this time, if the Beck smoothness of the surface of the base material 1 on which the image receiving layer 2 is formed is 80 seconds or less, when the image receiving layer 2 is formed, the surface of the image receiving layer 2 becomes rough and printing defects occur. If it is not suitable and is 200 or more, the ink absorbability of the substrate 1 itself is deteriorated and the imprintability is deteriorated. If the halftone dot ratio of the image-receiving layer 2 formed on the substrate 1 is 60% or less, the area of the image-receiving layer 2 that receives the resin-melting ink ribbon will be insufficient and the printability will be reduced. If so, the surface of the substrate 1 is the image receiving layer 2
As a result, the base material 1 itself becomes poor in ink absorbability and the imprintability deteriorates.

Further, when the number of halftone dots of the image receiving layer 2 formed on the substrate 1 is 150 or less, the area of the image receiving layer 2 receiving the resin-melting type ink ribbon is insufficient and the printability is deteriorated.
If it is 300 lines or more, it is difficult to form an accurate print on the image receiving layer 2, and the surface of the substrate 1 is hidden by the image receiving layer 2, so that the ink absorbability of the substrate 1 itself deteriorates and the marking is performed. Sex decreases.

[Composition of Image Receiving Layer 2] -Photopolymerizable Oligomer Polyester Acrylate ---- 60 parts by Weight-Reactive Diluent Polyfunctional Acrylate --- 20 parts by weight Photoinitiator mixed photoinitiator 5 parts by weight Photoinitiator auxiliary amine Auxiliary agent: 1 part by weight, extender pigment: Silica (grain size: 1 μm) 30 parts by weight It is desirable that the ratio of halftone dots is in the range of 60% to 95% and the number of halftone dots is in the range of 150 to 300 lines because good image receptivity and imprintability are obtained.

Next, a coating composition having the following composition was sufficiently stirred with a high-speed propeller stirrer, printed on the image-receiving layer 2 by a gravure printing method, and dried at 200 ° C. for 10 seconds to form a tint block 5 having a dry thickness of about 2 μm. Formed.

[Composition of the tint block 5] -Polyester resin (resin content 30%) [Product name: Byron 20SS (manufactured by Toyobo Co., Ltd.)] ... 30 parts by weight-Pigment [Product name: Microlith Blue 4GK (manufactured by Nagase Ciba Co., Ltd.): 1 part by weight toluene: 69 parts by weight Ride obtained in this way When a thermal transfer printing test was performed on the image receiving layer 2 of the ticket paper using a resin-melting type ink ribbon used in a normal ticket issuing device, clear characters could be printed, and printing was performed using a water-based stamp ink. When a suitability test was conducted, a clear seal was obtained.
