Colour-proofing sheet and production process.

摘要

The invention provides a method for protecting an image which comprises providing a colored image on a substrate and either: A. Applying an antiblocking layer to a release surface of a temporary support; bonding a thermoplastic adhesive layer to said antiblocking layer; laminating said applied support to said colored image via said adhesive; and peeling away said temporary support from said antiblocking layer; or B. applying a thermoplastic adhesive layer to a release surface of a first temporary support; applying an antiblocking layer onto a release surface of a second temporary support, laminating said adhesive onto said colored image and peeling away said first temporary support; and laminating said antiblocking layer onto said adhesive layer and peeling away said second temporary support; wherein said adhesive layer is substantially nontacky at room temperature, is laminated at temperatures between about 60 DEG C. and 90 DEG C., and comprises one or more thermoplastic polymers or copolymers; and wherein said antiblocking layer comprises one or more organic polymers or copolymers, which layer does not cohesively block at about 50 DEG C. or less.
