The present invention generally relates to the design and manufacture of nanofiber layers, webs, films, or membranes that may be self-supporting and can function as standalone products. More particularly, the present invention relates to a microporous nanofiber films and the use of such films in a wide variety of products and applications, including applications where physical property tuning is typically limited. Generally, the microporous films of the present invention can function as a standalone nanofiber membrane or can be bonded to other microporous films to produce a layered stacked film stack with customizable properties. Unlike conventional microporous films available in today's market, the microporous films of the present invention can be lighter, require less raw material cost to produce, and can improve operating performances in a variety of applications.

Provided is an aqueous ink for ink jet, containing a resin particle, and a cyclic amide-based, water-soluble organic solvent. The resin particle has a core portion that contains a cyano group-containing unit, and a shell portion that contains an aromatic group-containing unit, an anionic group-containing unit and a unit derived from a crosslinking agent, but free of cyano group-containing unit. Ink jet recording using the aqueous ink can record images that excel in abrasion resistance and gloss clarity.
