A process for preparing a flexible packaging material () by laminating at a temperature greater or equal to 50&#xb0; C. a printed substrate coated with a primer () comprising poly(acrylic acid) and/or poly(methacrylic acid) with another substrate coated with a thermal active material (), to prepare a high performance flexible packaging multilayer material () showing improved shelf-life, without requiring curing stage of intermediate layers.

Immediate and high performance flexible packaging applications using thermal lamination and new primer technology

Herein is described a method of producing a printed label. The method may comprise: a. providing a label substrate having a first surface and a second surface, wherein the first and second surfaces form opposing surfaces of the label substrate; b. applying a primer comprising a cross-linkable primer resin onto the first surface of a label substrate to form a primer layer; c. electrophotographically printing onto the primer layer an electrostatic ink composition comprising a cross-linkable thermoplastic resin to form a printed layer; d. applying a cross-linking composition comprising a cross-linking agent to the printed layer, wherein the cross-linking agent penetrates into the electrostatic ink composition and the primer layer; and e. activating the cross-linking agent wherein an adhesive is present on the second surface of the label substrate in step a or applied to the second surface of the label substrate at any point in the method after step a. Printed labels are also described herein.

Labels

Described herein is a process for preparing a flexible packaging material (). The process may comprise: providing a base material () having a first surface () and a second surface (), the first surface () having an electrostatic ink composition () printed thereon; providing a sealant layer () on the second surface () of the base material (); providing a flexible substrate () on which a thermally activatable laminating layer () has been deposited; and contacting under conditions of heat and/or pressure the thermally activatable laminating layer () disposed on the flexible substrate () with the first surface () of the base material () on which the electrostatic ink composition () is printed.

Flexible packaging material

Herein is described a method of printing on a textile substrate. The method may comprise: a. applying a primer comprising a cross-linkable primer resin onto a surface of the textile substrate to form a primer layer; b. electrophotographically printing onto the primer layer an electrostatic ink composition comprising a cross-linkable thermoplastic resin to form a printed layer; c. applying a cross-linking composition comprising a cross-linking agent to the printed layer, wherein i. the cross-linking agent penetrates into at least the electrostatic ink composition and the primer layer; and/or ii. the cross-linking agent is a non-isocyanate agent; and d. activating the cross-linking agent. Printed textiles are also described.

Textile printing

The present disclosure relates to a process for printing a substrate. The process comprises applying an analogue primer over a print substrate. A transparent electrophotographic composition comprising a coupling agent is electrophotographically printed on the primer as a coupling layer. An electrophotographic ink composition is then printed on the coupling layer to form an image layer. The coupling layer is disposed between the primer and image layer and in contact with each of the primer and image layer.

Printing substrates

Flexible packaging materials with electrophotographically printed images or information, and processes for preparing such flexible packaging materials are disclosed.

Described herein is a process for preparing a flexible printed material. The process may comprise providing a flexible print substrate comprising a primer on a surface of the print substrate, the primer comprising a primer resin; printing an ink composition comprising a thermoplastic resin onto the primer on the surface of the print substrate; and depositing a cross-linking composition comprising a cross-linker onto the printed ink composition disposed on the primer such that the thermoplastic resin of the ink composition is crosslinked and the primer resin of the primer is crosslinked.

Flexible printed material

Provided is an assembly including a block co-polymer film and a plurality of nano-rods; where the plurality of nano-rods are oriented at the surface of the block co-polymer film, substantially perpendicular to at least one interface between block co-polymer domains. Further provided are methods of assembly formation and devices including such assemblies.
