Appl. No.:

12/910934

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

G03C 1/005
G03C 1/494
G03C 7/46
G03C 1/46
G03C 7/00

US Classification:

430567, 430934, 430543, 430506, 430503, 430502, 430496, 430377, 430376, 430375, 430374, 430364, 430363, 430357

Abstract:

A multi-color photographic silver halide element has a total gelatin level on the imaging side of the support is less than 9000 mg/m, and bulk gelatin-to-junk weight ratio for all of the light sensitive layers on the imaging side of the support is greater than 1. 5. This weight ratio is defined by:Bulk gelatin-to-junk ratio=[()+()+()]÷()wherein Bis the total gelatin level for blue light sensitive layers, Bis the gelatin-to-junk ratio for blue light sensitive layers, Ris the total gelatin level for red light sensitive layers, Ris the gelatin-to-junk ratio for red light sensitive layers, Gis the total gelatin level for green light sensitive layers, and Gis the gelatin-to-junk ratio for green light sensitive layers. The imaging layers can be thinned without undesirable loss in sensitometric properties and in increase in dust and dirt generation while providing reduced material costs and improving development properties.

Appl. No.:

8/449149

Inventors:

Stephen J. Hassall - Churchville NY
Daniel R. May - West Henrietta NY
Martin E. Oehlbeck - Rochester NY

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

G03B 2732
G03B 3514

US Classification:

355 22

Abstract:

An image sheet (12) is coated with a radiation curable adhesive (48) at a coating station and then laminated to a lenticular array sheet (20) at a laminating station (50). A lamination of the image and array sheets is then positioned on an aligning station (56) where the lenticules of the array sheet are aligned with the image lines (16) of the image sheet. The adhesive is set at a curing station (60).

Assignee:

International Classification:

B32B 500
G03B 2502

US Classification:

156 87

Abstract:

A first sheet (10, 32, 56) is coated by a coater (47) with a pattern comprising a plurality of discrete domains (12, 34) of a low-viscosity adhesive and is then laminated to a second sheet (70) by a paired-roller laminator (62). The viscosity of the adhesive is sufficiently low and the pressure of the laminator sufficiently high that the plurality of adhesive domains (12) are caused to spread during lamination and to displace air from between the sheets, forming thereby a single domain of adhesive which just fills the space between the sheets without adhesive being extruded substantially beyond the edges of the sheets and without air bubbles or voids being entrapped between the sheets. In a preferred pattern, the domains (12) comprise stripes of adhesive with spaces (14) therebetween, the stripes being substantially parallel to the direction of lamination (16). The stripes can be joined by a connecting domain (20) at the leading edge (18) of the first sheet to enhance lamination near that edge, and can be notched or indented (28) at their distal or trailing ends to smooth the adhesive front at the completion of the laminating pass.

International Classification:

B65H 1826
B65H 1814

US Classification:

242547

Abstract:

A multiple durometer pressure roller for winding a web of deformable material onto a core, particularly for reducing air entrainment in the wound roll. The pressure roller includes a rigid cylindrical shaft, a resilient central sleeve supported by the shaft, and two end sleeves supported at each end of the resilient sleeve. The end sleeves have a lower durometer than the resilient sleeve. In a preferred embodiment, the end sleeves and the resilient sleeve are covered by an outer cover having a higher durometer.
