  • Patent number: 4957560
    Abstract: Cationic aqueous bituminous emulsion-aggregate slurries are disclosed to be formed with cationic emulsions prepared at elevated temperatures by emulsifying bitumen, such as an asphalt, in water with a cation-active emulsifier which is the product of the reaction of modified polyamine with certain polycarboxylic acids and anhydrides. The modified polyamides are obtained by reacting suitable polyalkylene amines with 1,2-unsaturated acids, able to undergo Michael addition of the amines across the double bonds resulting in amino acids which can undergo polymerization to low and high molecular weight amino polyamides.

  • Patent number: 4101322
    Abstract: A composition for improving the ink receptivity of lithographic printing images comprises an organic solvent liquid capable of softening the surface of the printing image and a film forming alkali-resistant oleophilic material such as a liquid hydrocarbon solution of a normally solid hydrocarbon or fat. The composition is for use in the case where the printing image is formed by alkaline development of an image-wise exposed radiation sensitive coating such as a phenol formaldehyde resin in admixture with a sensitiser. The composition may be applied before exposure to form an alkali resistant oleophilic layer on the radiation sensitive coating or it may be applied after image-wise exposure but before alkali development.
