  • Patent number: 4262054
    Abstract: A magnetic bubble memory device is disclosed in which a hardened film made of a heat-resisting highly-polymerized organic resin and having a predetermined thickness is employed for an insulating film interposed between a conductor pattern and a soft magnetic material pattern. In a conventional magnetic bubble memory device in which the above-mentioned insulating film is made of SiO.sub.2, an abrupt step is produced in the soft magnetic material pattern due to the existence of the conductor pattern beneath a portion of the soft magnetic material pattern, and the margin of bias magnetic field is thereby lowered. According to the present invention, the step is reduced and smoothed, and thus the lowering of the margin can be prevented.

The cured compositions are hard with good durability and surprising flexibility for such high aminoplast loadings.These compositions are particularly useful as coatings for resilient and rubbery substrates such as foam rubber, polyurethane foam and vinyl foam and on soft metal surfaces such as mild steel and aluminum.

  • Patent number: 4153754
    Abstract: The invention relates to a magnetic recording medium, for example a magnetic tape, which comprises a carrier and a magnetizable coating provided thereon which comprises a binder as well as a magnetic pigment dispersed in the binder by means of a dispersing agent. As a dispersing agent is used an N-acylsarcosine derivative. Herewith an optimum dispersion of the pigment in the binder is obtained in a short dispersion time. An excess of dispersing agent serves as a lubricant upon migration. The acyl group comprises preferably an aliphatic or olefinic hydrocarbon chain having 12-22 carbon atoms. Furthermore are to be preferred salts of N-acrylsarcosine, in particular metal salts, alkali metal salts, alkaline earth metal salts and amine salts.

  • Patent number: 4138528
    Abstract: Articles coated with a thermoset reaction product of a liquid resin composition comprising a reactive polymer and an N,N'-bis(alkoxymethyl)uron such as N,N'-bis(butoxymethyl)uron. The reactive polymer contains reactive groups such as hydroxyl and carboxyl and is of molecular weight in the range 300 to 5000. The uron ether is employed as a cosolvent for the polymer whereby the solution may be applied as a coating without the need for significant amounts of conventional solvents. Interaction between the polymer and the uron ether promoted by heat in the presence of acid catalyst shifts the role of the uron ether to that of a crosslinking agent for the polymer.

  • Patent number: 4130692
    Abstract: Coating compositions comprising alkoxymethylaminotriazines, polyols and polyether triols which are useful for low temperature cure, are low in viscosity to allow ease of coating without the need for appreciable amounts of solvent thinners, and provide coatings free from the problems of crawling, cratering, pinholing and "orange peel" formation. The alkoxymethylaminotriazines are preferably alkoxymethylmelamines. The polyols are polymethylol compounds in which oxygen atoms are separated by at least three carbon atoms of an aliphatic or alicyclic chain. The compositions may be cured in the presence of acid catalysts in the temperature range of 70.degree. to 105.degree. C.

  • Patent number: 4122054
    Abstract: This invention relates to high ortho etherified resole resins. The resole resins are prepared by reacting under acidic conditions phenol with formaldehyde in the presence of a divalent electropositive metal. The resole resins are then etherified with an alcohol and dehydrated to less than 1 percent water. The novel high ortho etherified resole resins are useful in coating, bonding and adhesive compositions. Such resoles are readily curable with coreactive resins providing chemical and solvent resistance.
