Adhesion Laser Transfer Printing

Apparatus for laser transfer printing is shown.

The apparatus utilizes a beam of infrared radiation to selectively transfer a part of a dye layer 10 from a substrate 12 to a record member such as paper 14. This recording is accomplished by producing a three-layer transfer member comprising substrate 12, dye layer 10 and an adhesive ribbon layer 16. Adhesive layer 16 is an infrared radiation absorbing material which comprises a delayed-tack adhesive.

Illuminating an area of the ribbon 16 with infrared radiation causes the adhesive to become tacky. Pressing the ribbon against the paper 14 causes the tacky adhesive to bond to the paper. Pulling the paper away from the ribbon 16 pulls off part of the dye and bonds it to the paper 14.

This apparatus has the advantage that the amount of heat required to record on the paper 14 is greatly reduced, since only the adhesive interface need be heated. The delayed-tack adhesive has the characteristic that it is not sticky at room temperature; however, after the adhesive has been heated to some temperature T1, it remains sensitive until it is cooled below temperature T2.
