Abstract: An intrachromospheruloid/intraleucospheruloid pigment composition and a process for producing the same: the intrachromospheruloid/intraleucospheruloid pigment composition consisting essentially of (a) spheruloids of essentially transparent organic polymer material, preferably cross-linked to essential insolubility in any physical solvent, having primary particles of an average size not exceeding 4 microns in diameter which have imbedded therein particulate organic color pigment composition consisting essentially of organic color pigment material having primary particles of an average size not exceeding 0.

Abstract: An intrachromospheruloid/inorganic pigment composition and a process for producing the same: the intrachromospheruloid pigment consisting essentially of (a) spheruloids of essentially transparent organic polymer material preferably cross-linked to essential insolubility in any physical solvent, having primary particles of an average size not exceeding 4 microns in diameter which have embedded therein particulate organic color pigment composition consisting essentially of organic color pigment material having primary particles of an average size not exceeding 0.2 micron in diameter and (b) an inorganic leuco pigment component combined with (a) to provide light reflectivity to the combination. In the process for its production, the organic color pigment material is reduced to an average particle size of 0.

Abstract: The strength of the bond obtained between substrates with the aid of phenoplasts, modified phenoplasts and/or epoxy resins, e.g. between fibrous material and an elastomer on vulcanization thereof, is improved by applying, to at least one of the substrates, in addition to a preformed phenoplast, modified preformed phenoplast, and/or preformed epoxy resin, and drying thereon before the assembly thereof with the other substrate, as an adhesion promoter, a quantity of m-aminophenol, which may be blended in a phenoplast adhesive, such as an RF dip or an RFL dip, or may be blended in the elastomer latex used for forming an RFL dip. Adhesive/promoter blends and latex/promoter blends for forming the same are also disclosed.
