Stanley Rapaport has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 4482662
    Abstract: An aerosol paint system is provided under sprayable pressures in a pre-packaged container adapted for instant spray application. The paint composition comprises a water-soluble monomer modified alkyd resin binder composition having a low molecular weight less than about 10,000 and an acid value (before neutralization) of above about 30 and preferably less than about 80. The product is diluted so that it is in a ready-to-use form when purchased. The paint system may be pigmented or non-pigmented (as for use in clear transparent coatings). Spray coatings of this invention deposit continuous films from pressurized containers at will.

  • Patent number: 4420575
    Abstract: An aerosol paint system under sprayable pressures in the container is provided comprising two film-forming polymeric binders. One of the two being monomer modified alkyd resin of relatively low molecular weight having an acid value (before neutralization with selected bases) of about 40 to 80 and the second polymeric binder of water-reducible nature being an emulsion polymer latex of high molecular weight, but capable of forming a continuous film in the total aerosol paint system aided by the monomer modified alkyd and a selection from co-solvents including in a first group low molecular weight alcohols, ketones, and esters and in a second group the co-solvents illustrated by the Cellosolves, Cellosolve acetates and other esters and the Carbitols as to chemical class.Pressures essential to spray application are principally provided by dimethyl ether and closely related ethers as a class.
