A method of forming features on substrates by imprinting is provided. The method comprises: (a) forming a polymer solution comprising at least one polymer dissolved in at least one polymerizable monomer; and (b) depositing the polymer solution on a substrate to form a liquid film thereon; and then either: (c) curing the liquid film by causing the monomer(s) to polymerize and optionally cross-linking the polymer(s) to thereby form a polymer film, the polymer film having a glass transition temperature (Tg); and imprinting the polymer film with a mold having a desired pattern to form a corresponding negative pattern in the polymer film, or (d) imprinting the liquid film with the mold and curing it to form the polymer film. The temperature of imprinting is as little as 10° C. above the Tg, or even less if the film is in the liquid state. The pressure of the imprinting can be within the range of 100 to 500 psi.

An improved method of forming features on substrates by imprinting is provided. In the method, a polymer solution that contains at least one polymer dissolved in at least one polymerizable monomer and the polymer solution is deposited on the substrate to form a liquid film thereon. Further, the liquid film is cured by causing the at least one monomer to polymerize and optionally cross-linking the at least one polymer to thereby form a polymer film, the polymer film having a glass transition temperature of less than 100° C., and the polymer film is imprinted with a mold having a desired pattern to form a corresponding negative pattern in the polymer film. Alternatively, the liquid film is imprinted with the mold and the liquid film is cured in the presence of the mold to form the polymer film with the negative pattern.
摘要:
A method for increasing adhesion between a substrate and a polymeric imprintable material during an imprinting procedure. The method includes chemically bonding a plurality of molecules to a surface of a substrate to form a self-assembled monolayer thereon. A monomer is copolymerized with the self-assembled monolayer to form a polymeric imprintable material that is chemically bonded to the self-assembled monolayer. Adhesion between the polymeric imprintable material and the substrate is substantially increased by the self-assembled monolayer.

The present invention is drawn to surface-crosslinked latex particulates, corresponding latex suspensions, ink-jet inks, and methods for making the latex particulates. A latex suspension can include a fluid medium and surface-crosslinked latex particulates. The surface-crosslinked latex particulates can be devoid of substantially all crosslinking below the particulate surface. Such surface-crosslinked latex particulates can be prepared with a plurality of monomers and at least one crosslinking agent.

The present disclosure is drawn to methods and compositions directed at durable ink-jet inks. As such, an ink-jet ink can have a liquid vehicle, a colorant dispersed or dissolved in the liquid vehicle, a high Tg polymer having a Tg of at least 45.degree. C. dispersed in the liquid vehicle, and a near-infrared absorbing dye in the liquid vehicle. The ink can be formulated such that when printed on a substrate and irradiated with a near-infrared energy source, the near-infrared absorbing dye generates enough heat to uniformly melt the high Tg polymer, thereby enhancing the durability of ink-jet ink printed on the substrate.
