Abstract
An image transfer product is provided which includes a phase change material in one or more layers of the product to regulate the temperature of the product during printing operations. The image transfer product may be in the form of a printing blanket, printing sleeve, electrophotographic/xerographic transfer blanket, image transfer belt, or roller which includes a print surface layer and at least one layer underlying the printing surface layer. The phase change material may be included in any of the layers of the image transfer product, but is not present at the upper surface of the print surface layer. The phase change material may be in the form of a powder, fibers, capsules, or combinations thereof.
Claims14
An image transfer product comprising a printing blanket or sleeve including a print surface layer, an elastomeric layer directly underlying said print surface layer, at least one fabric layer underlying said print surface layer, and a compressible layer underlying said print surface layer;
- wherein at least one of said layers includes at least one phase change material therein for regulating the temperature of said image transfer product ,said at least one phase change material has a melting point of from about 18° to about 45° C., and wherein said phase change material is not present in the upper surface of said print surface layer.
An image transfer product comprising a printing blanket or sleeve including a print surface layer, and at least one additional layer selected from the group consisting of an elastomeric layer directly underlying said print surface layer, a fabric layer underlying said print surface layer, and a compressible layer underlying said print surface layer;
- wherein at least one of said print surface layer or at least one of said additional layers includes at least one phase change material having a melting point of from about 18° C. to about 45° C. therein for regulating the temperature of said image transfer product, and wherein said phase change material is not present in the upper surface of said print surface layer.
