US Patent:

53287983, Jul 12, 1994

Filed:

May 5, 1993

Appl. No.:

8/057613

Inventors:

Kenneth J. McCarthy - Duxbury MA
Robert J. Pusateri - Rochester MA

Assignee:

Polaroid Corporation - Cambridge MA

International Classification:

G03F 709
G03F 734
G03C 1805

US Classification:

430200

Abstract:

A laminar thermal imaging medium, and a method of preparing same, are disclosed and include a photohardenable adhesive layer containing a photopolymerizable ethythenically unsaturated monomer, and a barrier layer for providing resistance to the diffusion of the polymerizable monomer therethrough to other layers of the thermal imaging medium. The barrier layer increases substantially the time period before which photohardening of the adhesive layer need be performed, during which time cutting and other manufacturing operations can be performed. The elastic and non-brittle character of the barrier layer provides improved durability of images prepared from the thermal imaging medium.

International Classification:

B41M 500

US Classification:

428500

Abstract:

An ink jet recording sheet comprises a support carrying an ink-receiving layer, this layer comprising a hydrophilic polymer, preferably poly(vinyl alcohol) and a poly(vinylpyridine). The images formed using this sheet display good water fastness.
