Abstract

An imaging member comprising a polymer sheet, a primer layer contacting said polymer sheet, and an image receiving layer contacting said primer layer; wherein said primer layer comprises: a) polyethyleneimine; and b) latex; wherein the latex has a Tg lower than 25° C. and c) hydrophilic colloid material.

Claims

1. An imaging member comprising a polymer sheet, a primer layer contacting said polymer sheet, and an image receiving layer contacting said primer layer;

wherein said primer layer comprises;

a) polyethyleneimine;

b) latex;

wherein the latex has a Tg lower than 25°

C. and

c) a material selected from the group consisting of water-soluble polyvinyl compounds, polyalkylene oxides, cellulose derivatives, dextran, gum arabic, zein, casein, pectin, collagen derivatives, collodion, agar-agar, arrowroot, albumin, polystyrene sulfonate, and polysaccharides.

2. The imaging member of claim 1 wherein the hydrophilic colloid material is gelatin or poly vinyl alcohol.

the latex is from 0.1% to 98%; and

the hydrophilic colloid is from 0.1% to 98%, based on the dry weight of the primer layer.

4. The imaging member of claim 1 wherein the weight ratio of polyethyleneimine is from 1% to 90%;

the latex is from 1% to 90%; and

hydrophilic colloid is from 1% to 98%, based on the dry weight of the primer layer.

5. The imaging member of claim 1 wherein the weight ratio of polyethyleneimine is from 1% to 25%;

the latex is from 1% to 25%; and

hydrophilic colloid material is from 50% to 98%, based on the dry weight of the primer layer.

6. The imaging member of claim 1 wherein the weight of the combined polyethyleneimine and latex is from 2% to 25%, based on the dry weight of the primer layer, with the rest being hydrophilic colloid material.

7. The imaging member of claim 1 wherein the polymer sheet comprises polyester.

8. The imaging member of claim 1 wherein the polymer sheet comprises polyethylene terephthalate.

9. The imaging member of claim 1 wherein the polymer sheet comprises polyethylene naphthalate.

10. The imaging member of claim 1 further having an imaging layer wherein the imaging layer comprises gelatin.
