Abstract
Thermally processable imaging elements in which the image is formed by imagewise heating or by imagewise exposure to light followed by uniform heating are provided with both a backing layer and an electroconductive layer to reduce static electricity effects and improve conveyance through processing equipment. The backing layer is an outermost layer and is located on the side of the support opposite to the imaging layer whereas the electroconductive layer is an inner layer and can be disposed on either side of the support.
Claims15
A thermally processable imaging element, said element comprising:
- (1) a support;
- (2) a thermographic or photothermographic imaging layer on one side of said support;
- (3) a backing layer which is an outermost layer and is located on the side of said support opposite to said imaging layer, said backing layer comprising a binder and a matting agent dispersed therein;
- and
- (4) an electroconductive layer which is an inner layer and is located on either side of said support, said electroconductive layer having an internal resistivity of less than 5.times.10.sup.10 ohms/square.
A thermally processable imaging element, said element comprising:
- (1) a support;
- (2) a thermographic or photothermographic imaging layer on one side of said support;
- (3) an overcoat layer overlying said imaging layer;
- (4) a backing layer which is an outermost layer and is located on the side of said support opposite to said imaging layer, said backing layer comprising a binder and a matting agent dispersed therein;
- and
- (5) an electroconductive layer interposed between said support and said backing layer, said electroconductive layer having an internal resistivity of less than 5.times.10.sup.10 ohms/square.
