THERMAL TRANSFER PRINTING RECEIVER |
摘要 |
<p>A thermal transfer printing receiver sheet for use in security laminates, comprises a substrate supporting a receiver coat of a dye-receptive composition on one side and a backcoat on the other, wherein the backcoat comprises a thermoplastic polymer having a Tg less than 130 DEG C., and dispersed therein a particulate solid material in amount 1-24% by weight of the thermoplastic polymer and an average particle size of 0.3-10 mu m. The security laminates are prpared after printing the receiver with an image, by bonding a first cover sheet of plastics material to the printed receiver coat so as to overlie the image, and a second cover sheet of plastics material can be bonded to the present backcoat more readily than to a highly crosslinked backcoat, using common adhesives. For greater security, thicker than normal backcoats are used.</p> |
