Slit extended imaging element in improved conversion process

Abstract

The invention relates to an imaging member comprising an imaging layer and a base wherein said base comprises a closed cell foam core sheet and adhered thereto an upper and lower flange sheet, wherein said foam core sheet has a modulus of between 100 and 2758 MPa and a tensile toughness between 0.344 and 35 MPa, and wherein said upper and lower flange sheet has a modulus of between and 1380 and 20000 MPa and a toughness between 1.4 and 210 MPa.

Description

field of invention [0001] The present invention relates to an imaging element. In one preferred form, the present invention relates to supports for photographic, inkjet, thermal and xerographic media. More specifically, the present invention relates to a composite imaging element with a polymer foam layer that provides improved crack propagation during switching. Background of the invention [0002] In order for a hardcopy imaging support to be widely accepted by consumers for imaging uses, it must meet several requirements. As suggested in the Voice of the Consumer survey, consumer preferences for "imaging media" typically define a few basic imaging support properties within narrow ranges, such as basis weight, thickness, stiffness, smoothness, and gloss Spend. Supports with properties outside the typical range of "imaging media" suffer from poor consumer acceptance. [0003] In addition to these basic requirements, there are other special requirements for imaging suppo...

Problems solved by technology

While this imaging element is suitable for imaging purposes, poor material selection for each element layer can lead to uncontrollable cracks during the transition, which tend to easily bifurcate into the core / flange interface and subsequently dissipate away from the moving knife. Tearing of the flange layer at one point, thus producing hair-like debris hanging from the cut edge
