Printing sheet
A printing sheet is formed of a base material film, a toner fixing layer formed on one principal surface of the base material film, a planarization layer formed on the other principal surface of the base material film, an adhesive layer formed on the surface of the planarization layer, and a peeling film stuck on the surface of the adhesive layer. The base material film has a laminated structure composed of a white foamed PET film layer on the toner fixing layer side and a transparent non-foamed PET film layer on the adhesive layer side, and the strength of the printing sheet is improved by the combined use of the non-foamed PET film. The planarization layer is formed of a colored ink layer, e.g. white ink layer, and increases the bonding area of the adhesive layer with the base material film side, thereby achieving smooth peeling from an adherend.
Printed rigid plastic substrates
A process for preparing a printed rigid plastic substrate is described, the process comprising: providing a rigid plastic substrate comprising a primer on a surface of the rigid plastic substrate, the primer comprising a primer resin; printing a liquid electrophotographic ink composition comprising a thermoplastic resin onto the primer on the surface of the rigid plastic substrate; depositing a cross-linking composition comprising a cross-linker onto the printed electrophotographic ink composition disposed on the primer; and laminating the rigid plastic substrate with a flexible film such that the ink composition and the cross-linker are disposed between the rigid substrate and the flexible film and wherein the lamination of the rigid substrate with the flexible film causes cross-linking of the thermoplastic resin of the ink composition and of the primer resin.
Image forming method and image forming apparatus
An image forming method is provided. The image forming method includes: forming an electrostatic latent image on an electrostatic latent image bearer; developing the electrostatic latent image on the electrostatic latent image bearer with a toner to form a toner image; transferring the toner image from the electrostatic latent image bearer onto a continuous resin film; fixing the toner image on the continuous resin film with a heat roller or a heat belt. The toner contains a maleic-acid-modified polyolefin having a polypropylene block in a main chain.
METHOD OF ENCHANCING ADHESION OF LIQUID TONER PRINTED ON A SUBSTRATE, AND PRODUCTS THEREFROM
A method of improving the adhesion of a liquid ink to a substrate where the ink is applied to the substrate using an LEP printing process, and products therefrom.
PRINTING SYSTEMS AND METHODS INCLUDING MULTILAYER FILMS
Embodiments of the present disclosure are directed to printing systems and methods that may include an ink composition including electrically charged ink particles dispersed in a hydrocarbon liquid and a multilayer film. The multilayer film may include a polymeric core layer; and one or more printing layers adjacent to the polymeric core layer. The one or more printing layers may include at least 50 wt. % of an ethylene vinyl acetate copolymer having acid and acrylate functional groups. The ethylene vinyl acetate copolymer having acid and acrylate functional groups may include from 0.5 wt. % to 4 wt. % methacrylic or acrylic acid; from 0.5 wt. % to 4 wt. % acrylate, from 7 wt. % to 40 wt. % vinyl acetate; and the balance ethylene, based on the total weight of the ethylene vinyl acetate copolymer having acid and acrylate functional groups.
TONER FOR DEVELOPMENT OF ELECTROSTATIC IMAGES
The invention relates to a toner for development of electrostatic images excellent in fusing property on polypropylene films and excellent in rubfastness of printed images, and a resin composition for a toner for development of electrostatic images. The toner for development of electrostatic images and the resin composition for a toner for development of electrostatic images each contain an amorphous polyester-based resin A and a crystalline polyester-based resin C, wherein the amorphous polyester-based resin A has a constituent moiety derived from a polyester resin, and a constituent moiety derived from a reactive functional group-having modified polyolefin-based polymer A, the polyester resin-derived constituent moiety and the modified polyolefin-based polymer A-derived constituent moiety being bonded via a covalent bond, and the amount of the modified polyolefin-based polymer A-derived constituent moiety is 5% by mass or more and 30% by mass or less relative to the total amount of the resin component in the toner.
Print media
A print medium can include a cellulose-based paper substrate with a first surface and a second surface opposite the first surface. The first surface can be treated with an electrically charged treatment layer. An ink-absorbing layer can be positioned on the electrically charged treatment layer. The ink-absorbing layer can include a polymeric binder and surface-activated fumed silica particles. The surface-activated fumed silica particles can include fumed silica particles that are surface-activated with charged multivalent aluminum salt and organosilane reagent. In further detail, an ink-receiving layer can be positioned on the ink-absorbing layer. The ink-receiving layer can include amorphous silica particles, alumina particles, or a combination thereof.
DIGITALLY PRINTED LABELS
Described are primer coatings, overprint varnishes, and seaming solution solutions for application to substrates such as those used to make wrap around and sleeve labels, particularly shrink wrap labels, which are used to label containers. The labels can be digitally printed with or without lane priming. With certain seaming solutions, the labels can be removed in the wash stage to enable the recycling of containers.
