Publication number: 20130045330Abstract: Methods are generally disclosed for forming and using a casting paper. In one embodiment, the casting paper can be made by coating a first surface of a base sheet with a release coating such that the release coating covers the entire first surface of the base sheet. A printed release coating is then applied on a portion of the first release coating, and is dried or cured as needed to form the casting paper having a textured surface defined by elevated areas corresponding to the printed release coating and valley areas corresponding to exposed areas of the printed release coating. In another embodiment, the casting paper can be made by first printing a base sheet with a patterned, structured coating, then coating over the patterned, structured coating with a release coating such that the release coating covers at least the unprinted areas of the base sheet. The casting paper can be used to form a texturized surface in a substrate.Type: ApplicationFiled: August 19, 2011Publication date: February 21, 2013Applicant: NEENAH PAPER, INC.Inventors: Frank J.

Patent number: 8172974Abstract: Methods and products for forming a coated image on a substrate are generally disclosed. The methods can include forming an image on a printable surface of a transfer coating layer of a printable transfer sheet. In a separate step, the negative mirror image of that same image is printed with toners on a toner printable sheet. After registering the sheets together, a portion of the transfer coating layer of the printable transfer sheet is transferred to the toner printable sheet, such that the portion of the transfer coating layer transferred to the toner printable sheet corresponds to the imaged areas on the toner printable sheet. However, the image formed on the printable surface of the transfer coating layer and the underlying transfer coating substantially remain on the printable transfer sheet. Thereafter, the image and the transfer coating layer remaining on the printable transfer sheet are transferred to a substrate.Type: GrantFiled: October 25, 2007Date of Patent: May 8, 2012Assignee: Neenah Paper, Inc.Inventor: Frank J.
