A device has a substrate in which base components are formed on base plates and functional films are formed on the base components. On the base components, lyophilic films having a lyophilic property to liquid forming material for forming the functional films are provided, and on these lyophilic films, functional films are provided.

Recording material comprising a substrate and an ink-receiving layer(s) provided on at least one surface of the substrate, wherein the ink-receiving layer comprises polyvinylpyrrolidone and a basic (meth)acrylic acid ester copolymer prepared from at least four kinds of monomers, which can be used in common for ink-jet printing, direct thermal transfer printing, PPC and pen plotter printing.

A recording medium has an ink-receiving layer of a condensation product of sorbitol with an aromatic aldehyde, polyvinylpyrrolidone and a resin, wherein the resin has a main component of a unit with hydroxyl group represented by a following Formula (I) ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 independently denote hydrogen or methyl; R.sub.4 denotes a group represented by ##STR2## m is an integer of 1-20, R.sub.5 denotes a group represented by --C.sub.l H.sub.2l --, l is an integer of 1-4.

A processed paper for documents protected from being photographically and electrostatically reproduced comprises a paper substrate having a front surface, and a colored ink layer and a silvery ink layer coated over the front surface of the paper substrate, the silvery ink layer having a pattern formed thereon to cause photographic and electrostatic reproductions of information recorded on the processed paper to be illegible due to irregular reflections of light from the pattern on the silvery ink layer.

The present invention is directed to a polymer matrix coating used for ink jet recording media. The polymer matrix coating has a glass transition temperature that is greater than or equal to about 120.degree. C. and less than or equal to about 300.degree. C., an integrity value of greater than or equal to about -20% and a swellability of greater than or equal to about 50%. The coating avoids the problem of pigment ink cracking that can occur in conventional ink jet recording media.
