Abstract

A process for producing a card comprising:

recording variable data comprising photographic data on at least one selected from a surface of a center core to be used for the card, and a back surface of an oversheet in a sheet form supplied from a roll thereof, by variable data recording means comprising a sublimation type thermal transfer device which uses a thermal transfer sheet having a dye layer imparted with a releasability,

superposing the center core and the oversheet to form an integral laminate;

cutting the integral laminate into a card form having a predetermined size.

Claims

1. A process for producing a card comprising:

forming a continuous card substrate for producing a card by supplying a plurality of continuous resin sheets from rollers and then superposing the sheets;

supplying an oversheet in form of continuous sheet from a roller;

recording variable data comprising photographic data on at least one selected from a surface of the card substrate and a back surface of the oversheet by variable data recording means comprising a sublimation type thermal transfer device which uses a thermal transfer sheet having a dye layer imparted with a releasability;

superposing and temporarily bonding the card substrate and the oversheet to form a continuous laminate;

integrally bonding the temporarily bonded continuous laminate by passing through an endless belt-type hot pressing means; and

cutting the integrally bonded continuous laminate into a card having a predetermined size.

2. A process according to claim 1, wherein the dye layer of the thermal transfer sheet comprises a dye and a resin binder comprising a graft copolymer containing a releasing segment.

3. A process according to claim 1, wherein the dye layer of the thermal transfer sheet comprises a dye, a resin binder and a release agent comprising a graft copolymer containing a releasing segment.
