Description

  The present invention relates to a card that is excellent in design and that is fun to hold.

In recent years, membership cards have been issued in various fields to lock in customers.
In athletic facilities, entertainment-related facilities, etc., card members can, for example, use facilities preferentially and purchase products sold in the facility at a lower price than non-members.
A membership card used in a store or the like is issued in the store, and the card member can preferentially obtain campaign information by direct mail or purchase a product at a low member price.
In addition, a point card or the like is issued at the time of product purchase, and point information on the purchase amount of the customer is recorded on the card every time the product is purchased, so that the member can receive a service corresponding to the accumulated points.
In addition, prepaid cards such as gift cards and electronic money are issued and used to purchase goods and services.
Both cards are issued to encourage the purchase of goods for the customer's continued visit.

The above-mentioned membership cards and point cards are issued according to the intentions of facilities and shops. However, customers with a wide range of activities cannot store all cards in their wallets and leave them at home except for cards that are frequently used. In many cases, a neglected card is forgotten.
For this reason, card issuers devise their card designs so that customers can always carry them with them and visit them frequently.

Since credit cards and the like need to be used internationally, they are made in conformity with the ISO (International Organization for Standardization) standard.
A credit card company issues a card conforming to the ISO standard by pasting a transparent cover sheet on the front and back of an opaque core material to a predetermined thickness and forming a magnetic stripe or IC module on the outermost surface.

On the other hand, membership cards and point cards issued at stores and the like do not necessarily conform to the ISO standard, so they are planned and issued with a unique design and a conspicuous design.
Therefore, a card in which a fluorescent dye is kneaded into a part of a card substrate is provided (for example, see Patent Document 1).

JP-A-2-281999

In the invention described in Patent Document 1, since the fluorescent dye is mixed with the material itself, the card manufacturer cannot use the material used conventionally.
In addition, for a material manufacturer supplying card materials, since a series of molding equipment is contaminated with fluorescent dyes, it takes a lot of time to clean the molding equipment when returning to production of materials that do not use fluorescent dyes. There must be.

  In order to solve the above-mentioned problems, a first aspect of the card of the present invention is a card in which a front cover sheet, one or more core sheets, and a back cover sheet made of a transparent resin material are sequentially laminated. In the core sheet and the front cover sheet, or at least part of the area between the core sheet and the back cover sheet, the two different colors of the light-collecting fluorescent dye ink are formed so as not to overlap each other. It is characterized by that.

  The second aspect is characterized in that, in the first aspect, the resin material is an amorphous polyester resin material.

  The third aspect is characterized in that, in the first aspect, the resin material is a polylactic acid resin material.

  The fourth aspect is characterized in that, in the first aspect, the resin material is a polyvinyl chloride resin material.

The fifth aspect is any one of the first to fourth aspects.
An information recording portion is formed on the exposed surface of either the front or back cover sheet.

With the card of the present invention,
1) Although only one color of light can be emitted from the conventional kneaded fluorescent dye kneaded into the card substrate, the card of the present invention emits two different colors of light from the side of the card substrate. In addition to the design effect, it exhibits a great effect as a countermeasure against counterfeiting.
2) In addition, card manufacturers use card base materials that have been used in the past, such as non-crystalline polyester resin materials, polylactic acid resin materials, and polyvinyl chloride resin materials. The card of the present invention can be produced simply by forming a condensing fluorescent dye printing layer with an ink containing the condensing fluorescent dye on the core sheet.
3) In addition, the card issuer side can provide the customer with a fun card to own.
4) In addition, since the information recording part is formed on the exposed surface of either the front or back cover sheet, the card information can be instantaneously read by the magnetic information reading device or the optical information reading device when the card is used. Can be saved.
