Title: Sulfomaleation of organic molecules and polymers
Inventor: THALER WARREN A
IPC: C08F8/46
Filed: 1987-12-11
Granted: 1992-06-16
Abstract: ABSTRACT   The present invention relates to novel organic compounds and polymers which are adducts of sulfomaleic anhydride, its isomers or derivatives, with unsaturated organic molecules wherein the novel products are produced by contacting sulfomaleic anhydride with an unsaturated organic compound to form the novel product.  In particular, the unsaturated organic molecule can be a hydrocarbon polymer ranging in molecular weight from about 500 to about 10,000,000.  The resultant adduct of sulfomaleic anhydride and the unsaturated hydrocarbon can be further reacted with a polyamine, which will neutralize the sulfonic acid group, as well as covalently bond to the copolymer by reacting with the anhydride group.  The amine salt can be converted to a metal salt by reaction with metallic bases.  The compounds and polymers are used as thermoplastic elastomers, disbursements, viscosity index improvers, drilling mud viscosifiers, and deflocculants, amongst other applications.

IPC: G03F7/40
Filed: 1988-01-27
Granted: 1993-05-18
Abstract: ABSTRACT        Disclosed is a multi-color transfer image forming method, which comprises subjecting a colored image forming material having a coloration recording layer comprising at least two layers and containing a photosensitive material and a colorant on a support to aqueous development after imagewise exposure, thereby forming a colored image, transferring the colored image to an image receiving member through the outermost surface of the coloration recording layer and then transferring at least one colored image with different hue onto the same image receiving member in conformity with the colored image.  The layer of the coloration recording layer remotest from the support is a layer adherable to the image receiving member, and only the colored image portion is transferred onto the image receiving member to have the image receiving member surface exposed at the non-image portion of the multi-color image.  According to the present invention, the treating process of multi-color transfer image becomes simpler and also a transferred image approximate to a printed matter can be obtained.
