Abstract
The present invention provides: a unit-piece printing sheet which gives unit pieces having a smooth cut on the periphery thereof and can be subjected to printing on both front and back of the unit pieces, as well as a process for producing the unit-piece printing sheet. The unit-piece printing sheet comprises both front and back printing base materials laminated via a thermoplastic resin film adhesive layer, wherein each of the printing base materials is divided into sections by forming a slit at each facing position of the front and back printing base materials to form unit pieces, and the portion of the thermoplastic resin film adhesive layer at the slit-forming position is made a breakable connecting portion.
Claims6
A unit-piece printing sheet comprising both front and back printing base materials laminated via a thermoplastic resin film adhesive layer, wherein each of the printing base materials is divided into sections by forming a slit at each facing position of the front and back printing base materials to form unit pieces, and the portion of the thermoplastic resin film adhesive layer at the slit-forming position is made a breakable connecting portion.
A process for producing a unit-piece printing sheet, which comprises making cuts on both the front and back of a laminate having both front and back printing base materials laminated via a thermoplastic resin film adhesive layer, to form slits for forming unit pieces from both the front and back printing base materials, whereby each of the printing base materials is divided into sections, and simultaneously the portion of the thermoplastic resin film adhesive layer at the slit-forming position is made a breakable connecting portion.
