Abstract: Highly branched polyamides prepared in a single step procedure of condensation polymerization of multifunctional monomer reactants comprising amine and carboxylic acid functional groups. Polymerization proceeds by reaction of an amine group of a first monomer unit with an acid group of a second monomer unit to form a reaction product having an amide linkage between the first and second monomer units and repetition of such amidation reaction between additional amine groups and acid groups of the multi-functional monomers and reaction products of the multi-functional monomers. In the present invention, in order to obtain a water soluble or dispersible hyperbranched polyamide, at least one of the multifunctional monomer unit reactants contains an amine, phosphine, arsenine or sulfide group, such that the highly branched polyamide contains in the backbone thereof an N, P, As or S atom capable of forming an onium ion.

Abstract: This invention provides a method of storing encoded data on an article comprising applying said data on a surface of the article, as an encodement invisible to the human eye under normal viewing conditions. The invention also provides materials for use in said method. This invention comprises an article having on a surface thereof data represented by a material applied to the article that forms a differential light pattern when illuminated which is capable of being read by a sensor capable of detecting said differential light pattern, said material being substantially invisible to the human eye under normal viewing conditions; wherein the light absorbance of at least a portion of the surface of the article underlying said data is different from the absorbance of the material comprising the data under the conditions in which the data is read.
