  • Patent number: 5720806
    Abstract: The invention provides a filler for ink jet recording paper which is composed of an amorphous silica containing 0.3-1.0% by weight of Al.sub.2 O.sub.3 and having a BET specific surface area of 250-400 m.sup.2 /g, a mean particle size of 3.6-10.0 .mu.m and a peak position of pore radius as measured by mercury injection method of 37.5-75 angstrom. A coat layer of ink jet recording paper formed of this filler excels not only in true circle property of dots and ink absorbing property when printed by ink jet recording system, but also in surface strength and writing quality. Furthermore, the coating liquid containing this filler has a low viscosity and hence exhibits good coating workability.

  • Patent number: 4656108
    Abstract: A resist film made of thiocarbonyl fluoride polymers which has excellent sensitivity, resolving power and adhesion property to a substrate and can provide a fine resist pattern. The resist pattern is produced by forming the resist film on a substrate, irradiating an ionizing radiation and developing with an organic solvent.

  • Patent number: 4421843
    Abstract: A process for forming a fluoroalkyl acrylate polymer film on a substrate by plasma polymerization. The fluoroalkyl acrylate polymer film has a high sensitivity to high energy rays and an excellent resolving power, and is very useful as a resist film. The plasma polymerized film of the invention has little pinholes, and is endurable to dry etching. A patterned resist film is prepared by irradiating the film with high energy rays to form a latent pattern and developing the latent pattern by either a wet process using a solvent or an oxygen or oxygen-containing gas plasma etching. Also, a pattern can be formed in the film by only electron beam irradiation. The pattern formation can be attained by electron beam delineation without development treatment.
