| 摘要 |
<p>The invention is concerned with synthetic resin mixtures comprising (A) an adduct of an excess of a solid polyaminoamide and an epoxy resin, and (B) an adduct of an excess of an epoxy resin and a solid polyaminoamide, the polyaminoamides in components (A) and (B) having an amine number of 30 to 200 and being obtained from dicarboxylic acids having 6 to 13 carbon atoms, optionally in admixture with other carboxylic acids, and certain cycloaliphatic diamines, optionally in admixture with other amines. The synthetic resin mixtures are used as binding agents for surface coatings and printing colours for both rapidly operating rotary printing machines and slowly operating printing processes. They are soluble in alcohol/ethyl acetate mixtures free from aromatic substances and are therefore environmentally tolerable, are suitable for sensitive printing processes, and immediately after evaporation of solvent they are surface dry so that they can be printed from roll to roll without difficulty.</p> |
