Abstract: A colored, transparent film-forming composition, which is made up of (a) a reaction product of an epoxy group-containing alkoxysilane (a-1) and an amino group-containing alkoxysilane (a-2) having active hydrogen therein, (b) an acid catalyst, (c) an alkali-soluble UV absorber, (d) at least one solvent selected from organic solvents having a boiling point of 100 to 250° C., and (e) a dye and/or a pigment, has a good coating performance and room temperature curing characteristic and can provide a film having good film strength and film removability after use. The coating method of the composition and the removing method of the film obtained from the composition are also described.

Abstract: The invention provides a tire polishing and protective composition including, as dissolved or dispersed in an organic solvent, 2 to 25% by weight of a silicone varnish, 0.1 to 4% by weight of a rubber type polymer and 0.1 to 10% by weight of a tackifier.

Abstract: A process for producing a dispersion composition suitable for use as a fuel is described, comprising kneading (a) a bituminous substance, (b) a low molecular weight aliphatic alcohol, and (c) water, a water-containing organic compound, or an aqueous organic compound suspension to provide a dispersion composition wherein the aqueous alcohol solution as a dispersed phase is dispersed in the bituminous substance as a continuous phase. By causing the phase inversion of the thus-obtained w/o type dispersion composition by kneading it along with a protective colloid at 5.degree. C. to 60.degree. C., and o/w type dispersion composition suitable for use as a fuel can be produced.

Abstract: There is disclosed a process for esterifying resin acids and rosins by reacting quaternary ammonium salts thereof with an alkyl or alkenyl polyhalide for about 2 to 6 hours at temperatures between about 20.degree. C. and 90.degree. C. There is also disclosed novel di-esters produced by the process and the use of the process to reduce the acid number of incompletely esterified carboxylic acid components of rosins and resin acids.

Abstract: A process for recovery of iodine from waste containing iodine or iodine compound, comprising the steps of burning the waste in a cumbustion chamber, and scrubbing out the iodine or iodine compound in the resulting combustion gas with a basic aqueous solution of sodium thiosulfate.
