Abstract
Assemblages that comprise a donor element and a receptor are disclosed. The donor element comprises a binder and particles of a cyanoacrylate polymer. The assemblages can be thermally imaged to form lithographic printing plates.
Claims20
An assemblage comprising:
- a donor element comprising:
- a donor support,
- a donor layer over the donor support, and
- a photothermal conversion material;
- and
- a receptor;
- in which:
- the donor layer comprises a binder and particles of a cyanoacrylate polymer;
- the donor layer is in face to face contact with the receptor;
- and
- either the donor support or the receptor transmits infrared or near infrared radiation,
- wherein the binder in the donor layer is selected from the group consisting of poly(vinyl pyrrolidone), poly(vinyl alcohol), polyethyleneimine, poly(ethyloxazoline), polyacrylamide, gelatin, polyacrylic acid, polyvinylimidazole, starches, dextrin, amylogen, gum arabic, agar, algin, carrageenan, fucoidan, laminarin, corn hull gum, gum ghatti, karaya gum, locust bean gum, pectin, guar gum, hydroxypropylcellulose, hydroxypropylmethylcellulose, hydroxyethylcellulose, carboxymethyl cellulose, polyvinyl pyrrolidone/vinyl acetate copolymers, and polyvinyl pyrrolidone/vinylcaprolactam copolymers.

A method for forming an image, the method comprising the steps of:
- (a) thermally imaging an assemblage comprising:
- a donor element comprising:
- a donor support,
- a donor layer over the donor support, and
- a photothermal conversion material;
- and
- a receptor;
- in which:
- the donor layer comprises a binder and particles of a cyanoacrylate polymer;
- the donor layer is in face to face contact with the receptor;
- and
- either the donor support or the receptor transmits infrared or near infrared radiation;
- and
- (b) separating the donor element from the receptor,
- wherein the binder in the donor layer is selected from the group consisting of poly(vinyl pyrrolidone), poly(vinyl alcohol), polyethyleneimine, poly(ethyloxazoline), polyacrylamide, gelatin, polyacrylic acid, polyvinylimidazole, starches, dextrin, amylogen, gum arabic, agar, algin, carrageenan, fucoidan, laminarin, corn hull gum, gum ghatti, karaya gum, locust bean gum, pectin, guar gum, hydroxypropylcellulose, hydroxypropylmethylcellulose, hydroxyethylcellulose, carboxymethyl cellulose, polyvinyl pyrrolidone/vinyl acetate copolymers, and polyvinyl pyrrolidone/vinylcaprolactam copolymers.
